The transmitter is intended for remote sensor monitoring. It has advantages where monitoring points are spread over wide areas or in small groups over several locations. It also offers a low-cost alternative to distributed PLC monitoring.
For users of the Ringline emergency stop system, unused channels may be used for analogue monitoring without compromising emergency stop functional safety.
The main application is for wide area condition monitoring of slow-moving process variables. Transmitters can be installed anywhere on the Ringline bus up to 7km from the Ringline Synchroniser (up to 12km on 666Hz system). Any transducer that produces a 4 to 20mA signal may be monitored via the two-wire network (Ringline). The assignment of Ringline addresses to the 4 input signals can be nominated on ordering or may be set / reset using a Ringline
Programmer.
