3.Compatibility

1794-IB32 module and Flex I/O communication adapters and terminal bases(such as 1794-TB32,1794-TB32S,1794-TB62DS,1794-TB62EXD4X15)are compatible.The terminal base provides input and power terminals and DIN rail mounting slots,and allows the module to be removed and inserted under power.

IV.Indicator lights

The module is equipped with 32 LED indicators,one for each input channel,to monitor the activity of each channel.The LED indicator lights up when a signal is received and turns off when there is no signal,making it easy to quickly identify active channels and verify normal working input devices.
