General Description:
The Switch/Proximity Detector Repeater type D6231E is a unit with eight independent channels suitable for applications requiring SIL 2 level (according to IEC 61508:2010) in safety
related systems for high risk industries.
The unit can be configured for switch or proximity detector (EN60947-5-6 NAMUR), NO or NC input and for NO or NC floating solid-state relay (photo-MOS) isolated output compatible
with logic circuits. Configuration is programmable from PC by the GM Pocket Portable Adapter PPC5092 via USB serial line and SWC5090 Configurator software.
Each channel enables a load to be controlled by a switch, or a proximity detector.
Fault detection circuit (configurable by PC) is available for all proximity sensors and switches equipped with end of line resistors. In case of fault, when enabled it de-energizes the
corresponding solid-state relay (photo-MOS) and turns the fault red LED on; when disabled the corresponding solid-state relay (photo-MOS) repeats the input line open or closed status
as configured.
D6231E has eight inputs and eight independent outputs. Modbus RTU RS-485 output is available on Bus connector.
Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards.

D6231 series must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards.
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.
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.
Warning
Operation
The Switch/Proximity Detector Repeater type D6231E is a unit with eight independent channels suitable for applications requiring SIL 2 level (according to IEC 61508:2010) in safety
related systems for high risk industries.
The unit can be configured for switch or proximity detector (EN60947-5-6 NAMUR), NO or NC input and for NO or NC floating solid-state relay (photo-MOS) isolated output compatible
with logic circuits. Configuration is programmable from PC by the GM Pocket Portable Adapter PPC5092 via USB serial line and SWC5090 Configurator software. Each channel enables
a load to be controlled by a switch, or a proximity detector.
Fault detection circuit (configurable by PC) is available for all proximity sensors and switches equipped with end of line resistors. In case of fault, when enabled it de-energizes the corre-
sponding solid-state relay (photo-MOS) and turns the fault red LED on; when disabled the corresponding solid-state relay (photo-MOS) repeats the input line open or closed status as
configured.
Note: use of voltage free electrical contacts with fault detection enabled (control equipment) requires, near the switch at the end of the line a R1=1 Ktypical (470 to 2 Krange)
resistor in series and a R2=10 ktypical (5 Kto 15 Krange) resistor in parallel to the contacts in order to allow the fault detection circuit to distinguish between a condition of
contact close/open and a line open/short circuit fault.
Installation
D6231 series modules are 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.
D6231 unit can be mounted with any orientation over the entire ambient temperature range.
Electrical connections 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. Connect only one individual conductor per each clamping point, use conductors up to 2.5 mm² (13 AWG) and a torque value of 0.5-0.6 Nm. Use only cables that are suitable
for a temperature of at least 85°C. 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.
The enclosure provides, according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The equipment shall only be used in an area of at least
pollution degree 2, as defined in IEC 60664-1.
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.
Any penetration of cleaning liquid must be avoided to prevent damage to the unit.
Any unauthorized modification must be avoided.
D6231 series must be connected to SELV or PELV supplies.
All circuits connected to D6231 unit must comply with the overvoltage category II (or better) according to EN/IEC60664-1.
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.
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, the “power on” green LED must be lit, output signal must be in accordance with the corresponding input signal value and input/output chosen transfer function,
Status/fault LED should reflect the input variable condition with respect to configured settings. If possible change the sensor condition and check the corresponding output.

General Notes:
SWC5090 Software can be downloaded for free at www.gminternational.com
PPC5092 Adapter is needed to interface PC to D6231E module.
The PC supplies the module via USB, therefore operating power supply (24 Vdc) is not
strictly needed when configuring the module.
Each channel has completely independent configurations.
See ISM0154 Manual for details on SWC5090 software.
