The GE Fanuc IC200ALG620 is a 4-channel RTD/resistance analog input module from the VersaMax I/O platform. It supports platinum (25/100/1000Ω), nickel (100/120Ω), nickel/iron (604Ω), and copper (10/50/100Ω) RTDs in 3-wire or 4-wire configurations with 16-bit resolution. The module provides internal RTD excitation current, 0.15% accuracy at 25°C, and optical isolation (250VAC continuous, 1500VAC 1 min) between inputs and logic. Onboard diagnostics detect open RTD, short circuit, under/over range, and wiring faults. Each channel is individually configurable. Applications include industrial temperature measurement, process control, HVAC monitoring, and any application requiring precision RTD-based temperature sensing in VersaMax distributed I/O systems.
**Q: Does the IC200ALG620 require external power for RTD excitation?**
A: No, the module provides internal excitation current for RTDs automatically—no external power supply is needed.
**Q: What RTD types are supported?**
A: Platinum (Pt25, Pt100, Pt1000), Copper (Cu10, Cu50, Cu100), Nickel (Ni100, Ni120), and Nickel/Iron (Ni/Fe 604) RTDs.
**Q: Can I mix 3-wire and 4-wire RTDs on the same module?**
A: Yes, each channel can be individually configured for either 3-wire or 4-wire RTD connection.
