Electrical Connection¶
The Digital Input/Output Module DC562 can be connected to the following devices via the I/O-Bus connector:
- S500 Bus Modules (e. g. CI592-CS31, CI501-PNIO, CI541-DP, CI581-CN)
- AC500 CPUs (PM5xx)
- other AC500 I/O Modules
Note
The DC562 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 chapters.
The electrical connection is carried out by using a removable 9-pole and 11-pole Terminal Block. These terminal blocks differ in their connection system TA563-TA565 Terminal Blocks for AC500-eCo I/O Modules and AC500-eCo \ CPUs (spring terminals or screw-type terminals, cable mounting from the front or from the side). The terminal blocks are not included in the module’s scope of delivery and must be ordered separately.
The following block diagram shows the internal construction of the digital inputs and outputs:
The assignment of the terminals:
| Terminal | Signal | Meaning |
|---|---|---|
| 1 | — | Reserved |
| 2 | C0 | Input/output signal C0 |
| 3 | C1 | Input/output signal C1 |
| 4 | C2 | Input/output signal C2 |
| 5 | C3 | Input/output signal C3 |
| 6 | C4 | Input/output signal C4 |
| 7 | C5 | Input/output signal C5 |
| 8 | C6 | Input/output signal C6 |
| 9 | C7 | Input/output signal C7 |
| 10 | — | Reserved |
| 11 | C8 | Input/output signal C8 |
| 12 | C9 | Input/output signal C9 |
| 13 | C10 | Input/output signal C10 |
| 14 | C11 | Input/output signal C11 |
| 15 | C12 | Input/output signal C12 |
| 16 | C13 | Input/output signal C13 |
| 17 | C14 | Input/output signal C14 |
| 18 | C15 | Input/output signal C15 |
| 19 | UP | Process voltage UP +24 V DC |
| 20 | ZP | Process voltage ZP 0 V DC |
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 DC562.
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.
The following figure shows the electrical connection of the Digital Input/Output Module DC562:
In this connection example, the inputs/outputs C0…C7 are connected as input and the inputs/outputs C8…C15 are connected as output.
The module provides several diagnosis functions Digital Input/Output Module DC562.
The meaning of the LEDs is described in Displays Digital Input/Output Module DC562.
