FLM-420-I2-W
Safety Notes
NOTICE!
Installation must only be performed by authorized and specialized personnel.
CAUTION!
Electrostatic discharge (ESD)! Electronic components could become damaged.
Ground yourself using a wrist strap or take other suitable actions.
Functional description
FLM-420-I2 Input Interface Modules provide 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;
alternatively, it can be surface mounted in the FMX-IFB55-S interface box (see Figure 7, Page 7 to Figure 8, Page 7).
Address Setting
Address setting is carried out using the 8 DIP switches and a suitable pointed object (see Figure 1, Page 3 to
Figure 5, Page 5).
Address (A) Operating mode
0 Loop/stub in LSN improved version mode with automatic addressing
1 - 254 Loop/stub/T-taps in LSN improved version mode with manual addressing
255 = CL Loop/stub in LSN classic mode (address range 127 max.)
Connection
See Figure 6, Page 6.
