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-D is installed on a DIN rail in accordance with EN 500022 with enclosed
adapter, see graphic 2.
For address setting, fit the rotary switches in the required position, see graphic 3.
For connection, see graphic 4.
