Functional description
FLM-420-I2 Input Interface Module provides three monitoring functions:
–
Monitoring a line with EOL resistor for standby or triggering (interruption/short circuit)
–
Monitoring a potential free contact for open and closed states
–
Voltage monitoring between 0 and 30 V DC.
The FLM-420-I2-W Type Wall-mount can be flush mounted in standard device boxes in
accordance with EN 60670, see graphic 3. Alternatively, it can be mounted in the FMX-IFB55-S
Interface Box Surface-mount, see graphic 4.
