2. Product description
The UT125 series of universal transmitters are designed for the affordable
transformation of standard signals, temperatures and potentiometer into a current
signal of 4..20 mA. The universal configurability of the measuring inputs reduces
the stock requirement for various applications.
The measuring inputs and analog output are not galvanically isolated.
The housing width of only 12.5 mm enables space-saving installation in the
switch cabinet.

2.2. Functional principle
An analog output with 4..20 mA is actuated depending on the selected measuring
range.
The temperature measuring ranges are linearised.
The device configuration takes place via DIP switch.
The power supply can be provided via an internal wide range power supply
(20..125 V DC / 20..253V AC) or via a DC voltage power supply with 24 V DC.
With the DC voltage power supply, the power supply can be done via the plug-in
device terminals or via a carrier rail bus (PowerRail) on the device, depending on
the device type.
2.3. Connection diagram
Input signals should be connected via separate 2 or 3 core cables.
Grounded leads may cause problems with the not galvanical isolated
analog true value output.

2.4. PowerRail
The 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 UT125LP provided for this purpose, the supply terminals 11
and 12 on the upper side of the device are omitted.

4. Controls and functional description
Selection of the measuring range takes place with DIP switches 1-4:
current / voltage, potentiometer, Pt100, thermocouple
The black fields symboli e the position of
the DIP switches
(When voltage and current are injected simultaneously the result is an addition of the input related signals)
The respective limit values can be adjusted with wheels A1 and A2.
The illuminated scales serve as an operating indicator.
When a limit value relay is not active, the adjustment wheel scale illuminates green.
When a limit value relay is active, the adjustment wheel scale illuminates red.
