10 Relay Module (optional)

The AirAlertTM96d-RM8 relay module acts as an output to the AirAlertTM96d controller. The relay module provides eight programmable relays for the activation of ventilation and audible/visual alarm output devices at programmable alarm levels. Since the relay module is an output to the controller, it can be located at any point within the gas detection network.

AirAlertTM96d-RM8 Features:

Fully compatible with the AirAlertTM96d controller

Equipped with 8 programmable DPDT relays

RS-485 daisy chain installation

LED visual indication status of each relay
