I. Features & Benefits
Microprocessor based relay controller that provides 7
different, field selectable application modes for two, three or
four door stations
3 field selectable Interlock (airlock) modes
Field selectable Communicating (shared) bathroom mode
Field selectable relay modes include:
- Conventional Relay (CR)
- Latching Relay (LR) – Pulse on, pulse off
- Time Delay Relay (TD) – 1-65 seconds
- Dual Function Relay (CR/LR, TD/LR, TD/CR, CR/CR)
Each output relay is field selectable as a dry contact or a
voltage output
