1. Intended use (areas of application)
Refer to the chapter 'Product description' for detailed specifications
for the area of application.
The operational safety of the device is only assured when used as
intended in accordance with the specifications in the operating manual.
Intervention beyond the actions described in the operating manual may only be
carried out by personnel authorised by the manufacturer for safety and warranty
reasons. Conversions or modifications made on one's own authority are
expressly prohibited.
Application-specific dangers can emanate from this device when used improperly
or not as intended.
Only device versions TS125L-Ex,TS125LP-Ex TS125M-Ex and
TS225M-Ex are permitted for use as accessory equipment for
connection of intrinsically safe sensors installed in Zones 0 or 1
and/or 20 or 21.
In the process, the safety-related characteristic data must be
observed.
The approval for all intrinsically safe equipment is voided if it has not
first been connected to an intrinsically safe circuit, because
compliance with the safety-related characteristic data must be 100%
guaranteed.
Therefore, a safety test must be carried out by the manufacturer
before later use as intrinsically safe equipment.
The devices TS125L-00, TS125LP-00 and all versions of the series
TS*****-Ex may be installed in Explosion Zone 2 under the following
conditions:
- Installation in a clean environment in a conductive, earthed housing
(switch cabinet) with a minimum protection rating of IP54.
- Transient overvoltages (with open switch contact) may not be
higher than 500V at the relay outputs.
- The connection terminals may only be disconnected in a de-
energised state
Applicable standards: EN60079-0 and EN60079-15.
General safety instructions, use
This operating manual must be kept in a location such that qualified personnel
can refer to it at all times.

Any processes described in this operating manual may only be carried out by
trained, qualified personnel who are authorised by the owner and wearing
protective clothing. All rights reserved.
1.1. Safety signs and symbols
Warning notices are identified in this document as described under Table 1:
DANGER
Warning! This symbol warns of imminent danger which can

in case of non-observance.

Attention! This symbol warns of potential dangers or harmful
situations which can cause damage to the device or to the
environment in case of non-observance.
Note! This symbol indicates processes which can have a direct
influence on operation or can trigger an unforeseen reaction in
case of non-observance.
1.2. Safety instructions
Read the product description before commissioning the device. Ensure that there
are no limitations for use of the product for the relevant applications.
The owner is responsible for ensuring the fault-free operation of the
device. The owner is obligated to ensure compliance and to observe
the required work and safety measures of the current applicable
regulations for the entire duration of use.
1.3. Product liability and warranty
Exclusion of liability:
The contents of the operating manual have been checked to ensure conformity
with the described device. However, deviations cannot be entirely ruled out.
Therefore, we cannot assume any guarantee for complete conformity. The
specifications in this document are checked regularly and any necessary
corrections are incorporated into subsequent versions. This document is subject
to technical changes. In addition, all claims are based on the valid 'Standard
Terms for the Supply of Products and Services of the Electrical Industry'.
GHM Messtechnik GmbH cannot inspect or repair any devices without
the required form having been filled in completely (refer to page 16
'Returns').

2. Product description
Switch amplifiers of the series TS125 and TS255 are used in switch cabinets for
the conversion and isolation of digital switching signals, optionally also in explosive
areas.
The devices are available in one- or two-channel versions.
All passive sensors, such as switching contacts, Namur initiators according to DIN
EN 60947-5-6, or passive electronic outputs of third-party devices, can be
connected to the optional intrinsically safe inputs.
The TS125 series in 12.5mm wide carrier rail housing offers relay outputs with
output make circuit.
The TS225 series in 22.5mm wide carrier rail housing offers relay outputs with
changeover function.
The devices may also be used in explosion zone 2 if they are installed in a suitable
housing.
Use in plants with functional safety SIL2 is also possible.

2.1. Scope of delivery
TS125 or TS225
this operating manual
2.2. Functional principle
The output relay and the diodes are controlled at the device front depending on
the status of the measuring inputs.
A maximum voltage of 8V is applied at a connected Namur sensor via the input
terminals. The sensor must limit the flowing current to two thresholds in
accordance with the Namur specification. Current lower than 1.2mA is identified
by the sensor as inactive; current higher than 2.1mA is identified by the sensor
as active. The range between 1.2mA and 2.1mA applies as hysteresis.
Alternatively, a switch contact can be connected. Then no current flows in the
open state and approx. 8mA flows in the closed state, wherein the previously
mentioned requirements are also fulfilled.
The front-side DIP switches can be used to select whether the input state is
directly or inversely transferred to the corresponding output relay.
The devices also offer the possibility of monitoring the input lines for a short-
circuit or wire break with the appropriate DIP switch settings.
In this connection, a current flow of less than 0.2mA applies as a wire break and
a current flow higher than 7mA applies as a short-circuit. With activation of this
monitoring function, the relays open in the event of a fault and the front-side
LEDs blink red. With connection of a simple switch contact, the error monitoring
must not be connected, because the error conditions are, in principle, always
fulfilled.
In order to also monitor the connecting lines for a mechanical switch contact,
resistors can be wired to the inputs according to the connection diagram below.
In the process, it is assured that the error thresholds recognised by the device
are only actually exceeded and/or undercut in the event of an error.

2.5. Carrier rail bus - PowerRail
The power supply voltage supply of multiple devices can be concentrated in the
mounting carrier rail (TS35 ) of a bus system.
An equivalent version is available for the entire LP series of GHM carrier rail
devices in 12.5mm wide housing.
Before mounting the device to be supplied, a series-compatible bus adapter must
be connected on the carrier rail.
For this purpose, an adapter piece is required for each device. The supply of the
bus then takes place via a plug-in terminal strip.
In the device version TS125LP provided for this purpose, the supply terminals 11
and 12 on the upper side of the device are omitted.
