Dräger REGARD 2400/2410 57
Configuration software
12.3 Expansion modules (optional)
Relay module: Addressing takes place automatically via the software. Address assignment is
between 4 and 7. In addition, the corresponding address must be set manually for each dip switch
on the relay module. (See corresponding section in the REGARD 2400/2410 operating manual).
I/O module: Addressing is automatically set to 8 and cannot be changed.
12.3.1 Relay module
Relay 1: General alarm Relay 1
Relay 2: General alarm Horn relay
Relay 3: General alarm Fault relay
Relay 4: Channel A Individual alarm 1
Relay 5: Channel A Horn relay
Relay 6: Channel A Fault relay
Relay 7: Transfer of the digital input DE1
Relay 8: Transfer of the digital input DE3 from the optional I/O module
Relay 9: Inhibit on/off, the relay switches when this function is called up.
Relay 10: Copy of the signal's on/off average value, the relay switches when this function
is called up.
Relay 11: Copy of the signal's on/off relay test, the relay switches when this function
is called up.
Relay 12: Deactivated
Inverted: On activation the signals of the controller are inverted
(for example: normally energised to energised on alarm).
12.3.2 I/O module
Output 1: Analogue 4 – 20 mA output for Channel A
Output 2: Analogue 4 – 20 mA output for Channel A average determination
Output 3: Analogue 4 – 20 mA output of the power supply 0 – 30 V
Output 4: Deactivated
Digital inputs: See “Digital Input DE configuration” on page 55.
WARNING
The switch-on delay is used to suppress fluctuating concentrations around the triggering
threshold.
