G4 Series Discrete and Analog I/O Relay Modules
Opto 22 I/O relay modules are designed for use in legacy and other systems
The Opto 22 G4 I/O was introduced in 1990, offering a more compact footprint than the earlier G1 and adding an LED status indicator on the top of the module. Many customers continue to rely on the G4 discrete and analog I/O in their legacy Optomux and Mystic systems. The G4 I/O is not just for legacy systems; many other installations use it as well.
Features
- G4 analog I/O:
- Provides complete electrical channel-to-channel isolation
- Isolation eliminates troublesome ground loop problems
- Wide variety of signal inputs includes RTD, ICTD, voltage, current, thermocouple, and TPO
- G4 discrete I/O:
- Ability to switch up to 3 A per channel
- Each module is individually fused
- Wiring terminals on the rack are easy to use
