Wiring For I/O Power Supply (C20T, C32T, M1T-E, M1T-Ei, And M1T-Eo Series) - Panasonic FP-M Hardware Manual

4-3. Wiring
3) Wiring for I/O power supply (C20T, C32T, M1T-E, M1T-EI, and M1T-EO series )
e.g.) C20T wiring diagram
24 V
Output connector
• I/O power supply
Input side:
- Use for driving the internal circuit.
- An external power supply is not required for the input connector.
- The 24 V DC terminal of the input connector can be used as the power supply for input field devices
(e.g., photoelectric sensors).
- The 5 V terminal on the input connector can supply 5 to 24 V DC.
Output side:
- Use for driving output field devices.
- When the load current is small (e.g., LED, etc.), drive by using the 24 V DC terminal of the output connector.
Note:
• The 24 V DC terminal or 0 V terminal of the I/O connector are connected internally.
• Current capacity range of I/O power supply
Id + Ic + Ie 1 A
Ic 0.5 A
If 0.5 A
Id: Current capacity for input of control board
Internal drive current 5 mA × number of ON points + current for field devices (e.g., photoelectric sensor)
Ic: Current capacity for output of control board
Internal drive current 3 mA × number of ON points + current for field devices
Ie: Current capacity for expansion board
If: Current capacity for output of expansion I/O board
Note:
• Consumption current of the intelligent/link board is as follows:
- Analog I/O board:
- FP-M transmitter master board: Max. 70 mA
- FP-M I/O link board:
