Alarm, One Relay, 4-20mA

The Delta Controls Model 341 Alarm is configured in a three inch discrete element modeling (DEM) package equipped with status LED lights and pushbuttons for setpoints, differential and delay. It is also equipped with voltage spike suppressors. Model 341 is for use with two-wire transmitters such as Delta Controls 500 Series pressure transmitter models and Model 173 capacitance level transmitter. These stand-alone devices can be used as alarms or differential control devices. It is suitable for tough industrial applications as it is rugged and sturdy, resists moisture, corrosion, and vibration due to epoxy potting.

One to three units can be mounted in a Delta Controls housing to provide various switch-sequencing functions such as alarm, differential control, and reverse / direct failsafe. They may be surface mounted or added to housings containing 4-20 mA transmitters to provide pump control, alarm, etc.
