* The rated output current is the value when using 60mA × 48 points for the
machine output (DO). Prepare a power supply that satisfies the 24VDC
output's total output current.
(Note)
Cables for the J4 connector must be manufactured by the machine tool builder.
(2) Remote I/O connections (CSH41A/B)
(a) Connection of the CSH41A connector
Connect the CSH41A connector to the RIO1/RIO2 connector of the control unit, or RIO3 connector of
the operation panel I/O unit.
