An industrial control system requires signals from the real world to be connected to IO modules capable of handling the type of various signals.

The G1 range of analogue IO modules from Opto 22 are rack mount, single-channel devices, which provide direct connection to analogue input and output process signals.

The G1 range of IO modules was the original Opto 22 single channel isolated IO series. A G1 analogue IO interface module provides direct connection to 5-types of analogue signals.

• Current Input – Single channel isolated module for 0/4 – 20 mA input
• Current Output – Single channel isolated module for 0/4 – 20 mA output
• Temperature Input - Single channel isolated module for various temperature inputs
• Voltage Input - Single channel isolated module for 0 – 10 VDC input
• Voltage Output – Single channel isolated module for 0 – 10 VDC output
