The flush-mounted IN Module is used to connect conventional pushbuttons and switches to the subnet. With the module 2 independent commands can be transferred to the BUS system. The buttons/switches are connected by means of wires. The difference to the standard IN-02U Module lies in the possibility of subaddress management. With this it is possible that four IN-02U-S4 Modules share one address.
| Operating voltage | 12-27V DC or 12-27V AC |

| Humidity | 0...85 % r.h. non-condensing |
| Protection class | IP 20 |
| Subaddress | DIP-9 | DIP-10 | Corresponds in the program to the outputs | |
|---|---|---|---|---|
| 0 | OFF | OFF | E**.1 | E**.2 |
| 1 | OFF | ON | E**.3 | E**.4 |
| 2 | ON | OFF | E**.5 | E**.6 |
| 3 | ON | ON | E**.7 | E**.8 |
Each four of these modules share one module address.
