2. Input and Output Wiring (Control and Expansion Boards)
1) Wiring for I/O power supply (C20R control board and E20R expansion board)
e.g.) C20R wiring diagram
• I/O power supply
Input side:
- Use for driving the internal circuit.
- An input power supply is not required for the E20R expansion board if COM (±) is connected to 24 V or 0 V,
because it is supplied by the internal circuit. Also, when COM (±) and the 24 V terminal are connected, they
become a source input. When COM (±) terminal and 0 V terminal are connected, they become a sink input.
Output side:
- Use for driving output field devices.
• Current capacity range of I/O power supply
Ic + Ie 1 A
Ic: Current capacity for output of control board
Internal drive current 7.5 mA × number of ON points
Ie: Current capacity for expansion board
Notes:
• I/O current capacity for E20R expansion board:
I a: Current capacity for input of expansion board
Internal drive current 5 mA × number of ON current for field devices
(e.g., photoelectric sensor)
I
b: Current capacity for output of expansion board
Internal drive current 7.5 mA × number of ON points
• Consumption current of the intelligent/link board is as follows:
- Analog I/O board: Max. 250 mA
- FP-M transmitter master board: Max. 70 mA
- FP-M I/O link board:
Max. 50 mA
