Introduction
Outputs
Analog output
0 to 22 mA sink or source (configurable)
Digital output
Modbus RTU
Relay output
5 A, 250 V AC, 24 V DC
The two relays can be used for fault signalling (normally energized) or
for alarm signalling. The relay assignments and operations are
configurable using the mobile app.

Relay Default Setting
Relay 1
Any faults and initial state is energized.
Relay 2
Gas alarm 1 and initial state is de-energized.
Maximum Power Consumption
The power consumption varies, depending on output version and
sensor type. The additional maximum power consumption for the relay
output version is 0.6 W.
