INNOVEC Controls has released the IDA dual set point alarm module. It accepts a 4mA-20mA or 0V-10V dc input signal and generates two alarm set points with 1% to 99% dead band.
The relays have changeover contacts which can switch 240V ac at 5A resistive. A scaleable nonisolated 4mA-20mA or 0V-10V dc retransmission output is provided as well as a regulated 24V dc loop supply to power two-wire transmitters.
The relays have LED status indication on the front panel and can be configured for failsafe high or failsafe low operation.
A common application for the alarm is to measure water levels using a two-wire ultrasonic which can be powered directly from the IDA, eliminating the need for a separate dc power supply. As the IDA has high and low alarm relays, the field staff can be alerted to excessive or minimum water levels.
The module is supplied in an enclosure that can be mounted on a din rail or equipment plate. It is powered from 120V/240V ac or 18V-36V dc.
