Alarm Relays With Improved Performance

Alarm Relays With Improved Performance

Acromag`s compact ac- and dc-powered alarms can handle more

applications with its electromechanical SPDT dry contact relays, now CSA-rated for 5 amps. The relay response time is now less than 100 milliseconds and the deadband can be set from 1 percent to 100 percent of the input spans for added flexibility to prevent false trips. The alarms accept input signal ranges of 0 to 20 mA dc and 0 to 1, 5, 20, 50 or 500 V dc. Models come with one or two relays for single- or dual-setpoint alarms that are adjustable for up to 115 percent of the input span. The alarms operate from -25 C to 75 C, quickly mount on DIN rails and have accessible setpoint voltage test points. Three-way isolation eliminates ground loops to simplify installation.
