The Dräger VarioGard® Relay Module is a module of the Dräger VarioGard® gas warning system. It can be installed at any point within a bus system, allowing on site activation of fans, warning signs and other actuators.
Contacts from five changeover relays are available, and each relay can be configured individually. The unit can be programmed to allow identification of the trigger event, a switching delay or an afterrun time. Additionally, external switches and keys to request e.g. alarm suppression, manual alarm triggering and alarm acknowledgment can be read by binary switching contacts via four digital inputs.
The electronics and control of the Dräger VarioGard Relay Module are powered via the Dräger VarioGard bus line.
