Coding
Multi-part I/O modules from the WAGO I/O-System can be equipped with coding keys to
prevent mismatching when connecting the individual module parts.
For additional information see: Assembling/Disassembling Components.
System Supply Power Requirement: Example Calculation
The example calculation is based on the following node structure:
• Head station
• 5 × 16-channel digital input module
• 5 × 16-channel digital output module
• 11 × 8-channel analog input module
• 10 × 8-channel analog output module
• 2 × relay module
• I/O module ...
Head station
5 × 16-channel digital input module (25 mA)
5 × 16-channel digital output module (40 mA)
11 ×8-channel analog input module (69 mA)
10 × 8-channel analog output module (61 mA)
Supply module
2 × relay module (100 mA)
I/O module ...
Field Supply Power Requirement: Example Calculation
The field supply layout must be handled in a similar manner as the system supply. In ad-
dition, power requirements for external actuators and sensors must be taken into ac-
count. Additional supply modules may be needed. Detailed product information is avail-
able in the respective
Determining Power Loss
Power loss depends on the node structure and the applied field signals. To roughly deter-
mine power loss, use:
• Head station: 3 W
• I/O module: 1 W

5.6.2 I/O Test

The WAGO I/O System allows easy, effective testing of your wiring with an I/O test.
For example, WAGO software solutions such as e!COCKPIT and
WAGO-I/O-CHECK make it possible to:
• Switch inputs and outputs
• Display digital input states
• Display analog input values
• Output analog values
