GE Fanuc IC200ALG266 VersaMax Analog Input Module

GE Fanuc IC200ALG266 VersaMax Analog Input Module — 15-Channel, 15-Bit, Current, TUV Approved

The IC200ALG266 is a 15-channel, 15-bit analog current input module from the GE Fanuc VersaMax series. It provides fifteen single-ended current inputs (4–20 mA default, 0–20 mA jumper-configurable) with a shared common return, all in one group. The module is TUV approved for SIL2 applications and features active input protection circuitry that limits current to 40 mA max if accidentally connected to +24V field power.

Key Specifications

• TUV Approved: Yes, for SIL2 / GMR safety-relevant systems
• Protection: Active circuit limits input current to 40 mA max on +24V accidental connection

Diagnostics & Faults

• Loss of Internal Power: Reported for field-side circuits
• Open Wire Fault: Reported per channel in 4–20 mA mode
• Internal Hardware Fault: A/D conversion malfunction detection; 3 consecutive failures stop scanning, OK LED off — requires power cycle or replacement

Compatibility

• All VersaMax carriers and CPU/NIUs
• Not compatible with DeviceNet NIU (IC200DBI001)

Installation Guide

1. Mount on compatible VersaMax I/O carrier (IC200CHSxxx series).
2. Configure range jumper: no jumper = 4–20 mA; jumper installed = 0–20 mA.
3. Wire 15 single-ended current inputs; all channels share a common return.
4. Ensure transmitter power is supplied externally — module does not power field devices.
5. Power on and verify OK LED illuminates green.

FAQ

Q: Is IC200ALG266 voltage or current input?
A: Current input (4–20 mA / 0–20 mA). Note: Some third-party sources incorrectly list it as voltage (-10V to +10V); that description applies to IC200ALG265. Always verify with official GFK-2526 manual.

Q: Does it need external power?
A: No. The module is powered entirely from the +5V backplane bus (100 mA max). However, external transmitter power must be supplied separately.

Q: What happens on CPU stop or communication loss?
A: Software-configurable: outputs can hold last state or go to default state for safe startup.

Q: Is it suitable for safety systems?
A: Yes. The IC200ALG266 is TUV approved for SIL2 and can be used in the safety-relevant portion of a GMR (Genius Modular Redundancy) system.

Q: What if I accidentally wire +24V to an input?
A: The module's active protection circuit limits input current to 40 mA max, protecting the sense resistors from damage.

Selection Tips

• 15-channel current input (TUV/SIL2): IC200ALG266
• 15-channel voltage input (TUV/SIL2): IC200ALG265
• 15-channel current input (non-TUV): IC200ALG264
• 15-channel voltage input (non-TUV): IC200ALG263
• 8-channel current/voltage (12-bit): IC200ALG260
• Always verify: Current vs. voltage, TUV requirement, and NIU compatibility before ordering
