2) Wiring description for I/O power supply (C20R control board and E20R expansion board)
■
Input side
• Supply a 24 V DC external power supply to the input circuit.
• Since the E20R is supplied input power through the internal circuit, the input voltage is not needed.
Note:
■
Output side
• The load power supply is supplied to each common terminal.
• Load current
