Specifications of Basic I/O Units Appendix A
CJ1W-MD232 DC Input/Transistor Output Unit
(MIL Connector, 16 inputs/16 Outputs, Sourcing)
Note The ON response time will be 20 µs maximum and OFF response time will be 400 µs maximum even if
the response times are set to 0 ms due to internal element delays.
