Failsafe Limit Alarm, 4 to 20mA DC input

Manufacturer's part number :


NATO number :


Manufacturer Acromag


Description :

The 260A accepts a 4 to 20mA input signal and provides a dry contact relay output if the input exceeds a user-defined setpoint limit. Power is received from the input loop.

These alarm relays are ideal for local failsafe alarming with existing process transmitters. They are easily installed on a process loop because they do not require an additional power supply and feature a very low voltage burden. A long list of features allows the 260A to adapt to most applications.
