Need 'Rate of Change' relay alarms with retransmit?

Never has a single off-the-shelf device incorporating so many features been available before now. Features such as Universal Input, 16-point linearisation, two "rate of change" or alarm trips, with retransmit output in mA, V or pulse are now available on the revolutionary Omniterm TTT Trip Amplifier.

The OMNITERM TTT Universal Input Dual Trip Module with additional Transmitter Output is designed for the widest range of signal conditioning and alarm/trip applications in a single off-the-shelf product, using advanced state-of-the-art digital measurement techniques, combined with extremely user friendly software configurability.
The input will accommodate most thermocouple and resistance bulb types, as well as voltages and currents from 1mV minimum to 10Vdc maximum input span.
This module has both Analogue transmitter output as well as two fully configurable alarm/trip relay contacts with “rate of change” alarms built in.
