Digital input interface DI-1
This is an input circuit in which the photocoupler cathode side is the input terminal. Transmit signals from a sink (open-
collector) type transistor output, relay switch, etc. The following connection diagram is for sink input.
*1 For interfaces of the CN3-1 pin, CN3-10 pin, and CN3-19 pin of the MR-J5-_G_-RJ_, approximately 4.3 k.
For interfaces of the CN3-16 pin, CN3-45 pin, and CN3-50 pin of the MR-J5-_A_-RJ_, approximately 4.3 k.
For interfaces of the CN3-7 pin, CN3-9 pin, CN3-15 pin, and CN3-22 pin of the MR-J5W_-_G_, approximately 4.3 k.
*2 It is 500 mA for the MR-J5-_A_.
The following diagram is for when the CN3-10 pin and the CN3-35 pin are used as digital input interfaces.
Refer to the following for source input.
