Digital Input Module
Collects digital output signals from field devices.
Compatible with 2-wire and 3-wire digital sensors.
Optocoupler isolation between internal bus and field input terminals.
Equipped with LED indicators for all digital input channels.
Remote firmware upgrade supported.
GKONE Group’s patented GK series digital input module is used to collect digital input signals on-site. The internal bus and field input are isolated by optocouplers and can be connected to 2-wire or 3-wire digital sensors.
There are 8 channels and 16 channels available, which can be connected to NPN or PNP devices, respectively. GKONE’s digital input module can operate stably in an environment of -45 degrees to 85 degrees and has an overcurrent (1.5A) protection function.
