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 toFigure 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
