This product is an accessory for the following products:
The Bacharach MGD controllers provide local alarm status indications (via multi-colored, per-channel LEDs) as well as single-level or dual-level digital (relay) alarm outputs based on 1, 2, 4, or 6 input signals and 1 or 2 user-definable set-points.
MGD Controllers support multiple input sensors/transmitters (1, 2, 4, or 6 channels) based on the model of the controller. Inputs are standard 4-20 mA signals from MGD-series sensors or any standard, linear, 4-20 mA transmitter.
MGD Controllers have either one or two relay outputs: one for single level alarm controllers ("Alarm"), and 2 for dual-level alarm controllers ("Alarm High" and "Alarm Low"). Unlike the alarm LEDs that provide a channel-by-channel alarm status of each incoming transmitter's signal, the relay output "trips" or "energizes" if any of the inputs exceed the alarm threshold set by the pot (that is, if any of the alarm LEDs is energized). Alarm relays can be used to activate warning lights, sirens, ventilation fans, etc.
For dual-alarm configurations, the Alarm Low relay output "trips" or "energizes" if any of the inputs exceed the alarm threshold set by the low alarm pot. Similarly, the Alarm High relay output "trips" or "energizes" if any of the inputs exceed the alarm threshold set by the high alarm pot. All controllers have a green power LED that is on when the unit has power. The 4- and 6-channel 2-level units have a fault relay which "trips" or "energizes" if the controller experiences a fault condition. Like the alarm relays, the fault relay can be used to activate warning lights, sirens, ventilation fans, etc.
