Specifications of Basic I/O Units Appendix A
CJ1W-MD263 DC Input/Transistor Output Unit
(MIL Connector, 32 Inputs/32 Outputs, Sinking)
Note 1. 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.
2. The following restrictions apply when connecting 2-wire sensors.
• Provide an input power supply voltage at least as high as the sum of the ON voltage (19 V) and
the sensor’s residual voltage (approximately 3 V).
• Use a sensor with a minimum load current of 3 mA or higher.
• When connecting a sensor with a minimum load current of 5 mA or higher, connect a bleeder
resistor.
