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. In addition, 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 Drager VarioGard Relay Module are powered via the Drager VarioGard bus line.
The Drager VarioGard Relay Module can be easily fitted to a DIN rail in a control cabinet using rail mount clips. For field installation, a suitable housing is available as a wall-mounting conversion kit.
