4-Channel Isolation Module ISO4N

4-Channel Isolation Module is an optically isolated input interface based on the PC817 optocoupler, providing a selectable input voltage range and an active-low NPN output. Screw terminals are provided for convenient input and output connections. An onboard jumper selects the input range: 3-9 V with the jumper ON or 10-24 V with the jumper OFF.

The output stage supports a wide 3-24 V output supply range, making the module suitable for interfacing control signals between electrically isolated circuits. Dedicated Yellow and Red LED indicators provide visual indication of input and output activity, respectively.

Mounting holes are provided for convenient installation, including DIN-rail mounting applications.
