The single channel Power Supply Repeater and Trip Amplifier D6254S provides a fully floating dc supply to energize conventional 2 wires 4-20 mA transmitters; it also accepts 0/4-20 mA current input signals, as well as ±12 V voltage inputs (also suitable for 0/1-5 V and 0/2-10 V signals). The module repeats/converts (in linear or square root scale) the input as on current signal, in a floating circuit to drive a load, suitable for applications requiring SIL 2 (according to IEC 61511) in safety related systems for high risk industries. The output signal can be in direct or reverse form.
Two independent Alarm Trip Amplifiers are also provided. Each alarm energizes or de-energizes an SPDT relay for low, high, window or fault repeater alarm functions.
The two alarm relays trip points are settable over the entire input signal range.
An optional alarm acknowledgement input is also provided.

Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards.


1 channel analog input for 2 wires loop powered or separately powered Smart transmitters or Current or Voltage signals, provides 3 port isolation (input/output/supply) and current (source or sink mode) output signal. In addition, it provides two SPDT relay alarm contacts with adjustable alarm trip point. The out-of-range (burnout) fault is repeated to the bus.
