DC Voltage/Current Input Limit Alarm 361A 461A

Acromag’s 361A 461A is a DC Voltage/Current Input Limit Alarm Module.

Firstly, these alarms accept DC voltage/current input signals and provide relay output if the input exceeds user-defined set-point limits.

Secondly, features make these alarms easy to use and well-suited for a wide range of limit monitoring and on/off controller applications. Three-way isolation eliminates ground loops to simplify installation. And for easier use in the field, these alarms withstand extreme temperatures. Plus, have accessible set-point voltage test points. Other features include alarm/power status LEDs and independent set-point and dead band adjustment pots.
