Electrical Connection¶
The Digital Input/Output Module DC561 can be connected to the following devices via the I/O-Bus connector:
- S500 Bus Modules (e. g. CI501-PNIO, CI541-DP, CI581-CN)
- AC500 CPUs (PM5xx)
- other AC500 I/O Modules
Note
The DC561 must not be used as a remote expansion module at DC505-FBP and CI590-CS31-HA Bus Modules.
Note
Mounting, disassembling and electrical connection for the I/O Modules are described in detail in S500 System Data S500 System Data, Overview.
The electrical connection is carried out by using the 20-pin Interfast connector. For further information, refer to the Interfast documentation.
The assignment of the terminals:
| Terminal | Signal | Meaning |

| 1 | C0 | Input/output signal C0 |
| 2 | C1 | Input/output signal C1 |
| 3 | C2 | Input/output signal C2 |
| 4 | C3 | Input/output signal C3 |
| 5 | C4 | Input/output signal C4 |
| 6 | C5 | Input/output signal C5 |
| 7 | C6 | Input/output signal C6 |
| 8 | C7 | Input/output signal C7 |
| 9 | C8 | Input/output signal C8 |
| 10 | C9 | Input/output signal C9 |
| 11 | C10 | Input/output signal C10 |
| 12 | C11 | Input/output signal C11 |
| 13 | C12 | Input/output signal C12 |
| 14 | C13 | Input/output signal C13 |
| 15 | C14 | Input/output signal C14 |
| 16 | C15 | Input/output signal C15 |
| 17 | UP | Process voltage UP +24 V DC |
| 18 | ZP | Process voltage ZP 0 V DC |
| 19 | UP | Process voltage UP +24 V DC |
| 20 | ZP | Process voltage ZP 0 V DC |
Note
The arrow located next to the Interfast connector marks terminal 1.
The internal power supply voltage for the module’s circuitry is carried out via the I/O-Bus (provided by a Bus Module or a CPU). Thus, the current consumption from 24 V DC power supply at the terminals L+/UP and M/ZP of the CPU/Bus Module increases by 10 mA per DC561.
The external power supply connection is carried out via the UP (+24 V DC) and ZP (0 V DC) terminals.
Attention
:strong:Risk of damaging the PLC modules!
The PLC modules must not be removed when the plant is powered on.
Make sure that all voltage sources (supply and process voltage) are switched off before you are
- connecting or disconnecting any signal or terminal block
- removing or replacing a module.
Attention
:strong:Risk of damaging the PLC modules!
The PLC modules can be damaged by overvoltages and short circuits.
Make sure that all voltage sources (supply and process voltage) are switched off before you are beginning with operations at the system.
Note
Process supply voltage must be connected to UP/ZP of the module. The inputs and UP/ZP must use the same power supply.
Note
If using DC561 with index A0, the process supply voltage must be from the source as the power supply voltage of the CPU. The index consists of 1 letter followed by 1 digit and can be found on the type plate of the module next to the type designator “DC561”.
The module provides several diagnosis functions Digital Input/Output Module DC561.
The meaning of the LEDs is described in Displays Digital Input/Output Module DC561.
