Alarm, One Relay, 4-20mA

The Delta Controls Model 341 Alarm modules are configured in the three inch discrete element modeling (DEM) package. These stand-alone devices can be used as alarms or control devices. From one to three units can be mounted in a Delta housing to provide various switch-sequencing functions. They may be surface mounted in user’s panels and cabinets. They may also be added to housings containing 4-20 mA transmitters to provide pump control, alarm, etc. Note that the modules are not loop powered and require a 24 DCV power source. This can be provided by the user, or from an integrally mounted isolated power supply module (option ‘PS’).
