Trigger Contact Relays in Echo Mode At Your Radio Towers...

How This Application Works:

Equipment Used:

Discrete Point Module (DPM) Discrete Control Module Wire Wrap Alarm Block

The Discrete Point Module has a capacity of 16 discrete inputs, and 2 control outputs. The 16 discrete inputs allow you to monitor 16 different environmental conditions. You can monitor such things as commercial power, door entry violation, room temperature etc. Anytime a fault alarm is detected; the DPM’s built in modem will dial up the DCM and trigger a specific contact relay.

The Discrete Control Module is the functional opposite of the DPM, in that it has 16 control outputs and 2 alarm inputs. When working in tandem like this, you can detect an alarm condition at one location, and perform a control operation at a 2nd remote location. Both network elements are software programmable.

In echo mode the DPM will communicate over a RS485 line on to your Discrete Control Module (DCM). The DCM relays operate when the DPM detects an alarm, providing 16 contact-closures that follow the alarm inputs point-for-point. Likewise, the DCM’s two alarm inputs operate the two respective relays at the DPM. This is especially useful in converting alarms between systems with unlike protocols or for transporting alarms from small remote sites to large, centrally located remotes or enunciator panels. Both DPM models can be used in the echo mode application and they will be powered by a –24V to 110V supply.
