General Description: The D5295S is a relay module suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508:2010 Ed. 2 for high risk industries. It
provides isolation between input and output contacts. A wide compatibility towards different DCS/PLC is guaranteed: driving line pulse testing, executed by DCS/PLC, is permitted by a
dedicated internal circuit, to prevent relay and LED flickering. Internal relay coil short circuit is detected by the module. D5295S has 2+2 SPST relay contacts connected in parallel and
then in series to avoid spurious trip and to increase availability (see function diagram). High availability SIL 3 Safety Function for NE load or F&G / ND load is available at Terminal Blocks
13-14. When the driving signal is high (24 Vdc), the relay is energized, contacts at terminals 13-15 and 14-16 are open and load is de-energized. When the driving signal is low (0 Vdc),
the relay is de-energized, contacts at terminals 13-15 and 14-16 are closed, the load is energized. Load is isolated from supply on both polarities: +/AC, -/AC.
Load and Line Diagnostic: Line and load short/open circuit detection is provided, with solenoid resistance measurement, even in presence of series connected diodes.
A patented proprietary resistance measuring technique performs the load short and open circuit diagnosis in de-energized load status, for DC or AC supply systems. Load RMS voltage
(before and after its energization) and current are measured by the module. Load voltage, current and resistance can automatically be acquired from field.
User configurable limits set the minimum and maximum values of load resistance, supply voltage (DC or AC) and load current. Earth leakage detection on both AC phases is available
in de-energized load condition. The fault in the field is directly mirrored to the PLC DO: few systems may exceptionally require an external resistor at terminals 7 and 8. All diagnostic
conditions, that detect a fault on line and load, open the fault relay contacts and are also available from a RS485 Modbus output to identify any specific fault. Diagnostic functions with
fault relay NO contacts are SIL 2 rated according to IEC 61508:2010 Ed.2 (Route 2H). Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination
Boards, in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
Functional Safety Management Certification:
G.M. International is certified by TUV to conform to IEC61508:2010
part 1 clauses 5-6 for safety related systems up to and included SIL3.
The module is fully programmable to set the operation parameters from PC by the GM Pocket Portable Adapter PPC5092 via USB serial line and SWC5090 Configurator software.
Measured values and diagnostic alarms can be read on both serial configuration or Modbus output line.

Warning
Operation
The single channel 5 A Relay Output D5295S is a relay module suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508:2010 Ed.2 for high risk
industries. It provides isolation between input and output contacts. D5295S has 2+2 SPST relay contacts connected in parallel and then in series to avoid spurious trip and to increase
availability (see function diagram). High availability SIL 3 Safety Function for NE load or F&G/ND load is available at Terminal Blocks 13-14. When the driving signal is high (24 Vdc), the
relay is energized, contacts at terminals 13-15 and 14-16 are open and load is de-energized. When the driving signal is low (0 Vdc), the relay is de-energized, contacts at terminals
13-15 and 14-16 are closed and the load is energized. Presence of diagnostic circuit power supply, status of input / output channel (energized or de-energized), as well as any type of
fault condition (line and load short/open circuit, relay coil short circuit, etc.) are displayed by related signalling LEDs: green power supply, yellow for status channel and red for fault.
Installation
D5295S is a relay output module housed in a plastic enclosure suitable for installation on EN/IEC60715 TH 35 DIN-Rail, with or without Power Bus or on customized Termination
Board. D5295S unit can be mounted with any orientation over the entire ambient temperature range. Electrical connection of conductors up to 2.5 mm² are accommodated by polarized
plug-in removable screw terminal blocks which can be plugged in/out into a powered unit without suffering or causing any damage (for Zone 2 installations check the area to be
nonhazardous before servicing). The wiring cables have to be proportionate in base to the current and the length of the cable. On the section “Function Diagram” and enclosure side a
block diagram identifies all connections. Identify the function and location of each connection terminal using the wiring diagram on the corresponding section, as an example:
Connect 24 Vdc power supply positive at terminal “9” and negative at terminal “10”.
Connect positive input at terminal “1” and negative input at “2”.
Connect Fault output 1 (30 V, 500mA) at terminals “3” and “4” and Fault output 2 (250 V, 3A) at terminals “11” and “12”.
Connect A- Modbus RS845 for diagnostic at terminal “5” and B+ at terminal “6”.
Connect positive output NE or F&G/ND load at terminal “13” and negative at terminal “14”.
Connect positive Load Power DC/AC at terminal “15” and negative at terminal “16”.
Connect ground at terminal “21”.
Installation and wiring must be in accordance to the relevant national or international installation standards (e.g. IEC/EN60079-14 Electrical apparatus for explosive gas atmospheres
Part 14: Electrical installations in hazardous areas (other than mines)), make sure that conductors are well isolated from each other and do not produce any unintentional connection.
Connect 2+2 SPST relay contacts checking the load rating to be within the contact maximum rating 5 A 250 Vac 1250 VA, 5 A 250 Vdc 140 W (resistive load). To prevent relay con-
tacts from damaging, connect an external protection (fuse or similar), chosen according to the relay breaking capacity diagram on data sheet. The enclosure provides,
according to EN60529, an IP20 minimum degree of mechanical protection (or similar to NEMA Standard 250 type 1) for indoor installation, outdoor installation requires an additional
enclosure with higher degree of protection (i.e. IP54 to IP65 or NEMA type 12-13) consistent with the effective operating environment of the specific installation. Units must be protected
against dirt, dust, extreme mechanical (e.g. vibration, impact and shock) and thermal stress, and casual contacts. If enclosure needs to be cleaned use only a cloth lightly moistened by a
mixture of detergent in water. Electrostatic Hazard: to avoid electrostatic hazard, the enclosure of D5295S must be cleaned only with a damp or antistatic cloth. Any penetration
of cleaning liquid must be avoided to prevent damage to the unit. Any unauthorized card modification must be avoided. According to EN61010, D5295 must be connected to SELV or
SELV-E supplies. Relay output contact must be connected to load non exceeding category II overvoltage limits. Warning: de-energize main power source (turn off power supply
voltage) and disconnect plug-in terminal blocks before opening the enclosure to avoid electrical shock when connected to live hazardous potential.
D5295S is an electrical apparatus installed into EN/IEC60715 TH 35 DIN-Rail located in Safe Area or Zone 2, Group IIC, Temperature Classification T4, Hazardous Area
(according to EN/IEC60079-15) within the specified operating temperature limits Tamb - 40 to +70 °C. D5295S must be installed, operated and maintained only by qualified personnel, in
accordance to the relevant national/international installation standards (e.g. IEC/EN60079-14 Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in
hazardous areas (other than mines)), following the established installation rules. De-energize power source (turn off power supply voltage) before plug or unplug the terminal blocks
when installed in Hazardous Area or unless area is known to be nonhazardous. Warning: substitution of components may impair suitability for Zone 2. Warning: de-energize
main power source (turn off power supply voltage) and disconnect plug-in terminal blocks before opening the enclosure to avoid electrical shock when connected to live
hazardous potential. Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless area is known to be
onhazardous. Failure to properly installation or use of the equipment may risk to damage the unit or severe personal injury. The unit cannot be repaired by the end user and must be
returned to the manufacturer or his authorized representative. Any unauthorized modification must be avoided.
Start-up
Before powering the unit check that all wires are properly connected, particularly supply conductors and their polarity, input and output wires. Check conductors for exposed wires that
could touch each other causing dangerous unwanted shorts. Turn on power for diagnostic circuit, the “power on” green led must be lit. Enabling input, the channel status yellow led must
be lit and load circuit must be de-energized because 2+2 SPST relay output contacts are open. Instead, disabling input, the channel status yellow led must be turned off and load circuit
must be energized because 2+2 SPST relay output contacts are closed.
Configuration during T-proof testing for functional safety relay and diagnostic applications
For configuration of T-proof relays and diagnostic circuits testing, some DIP Switches are located on component side of pcb. These switches allow the T-proof relays and diagnostic
circuits test (SW1 dip-switch: 1-2-3-4 set “ON” and see “Testing procedure at T-proof for functional safety relay and diagnostic applications” on ISM0442 Safety Manual).
WARNING: after T-proof test, dip-switch 1-2-3-4 must be set
to “OFF” position for normal operation.
