GE IC200ALG266 VersaMax Analog Input Module
The GE IC200ALG266, also cataloged as the IC200ALG266 Analog Input Module, operates as a dedicated hardware component for multi-channel current signal acquisition within VersaMax I/O networks. The unit processes field sensor signals across 15 single-ended channels, translating analog current inputs into digital data registers via a 15-bit resolution A/D converter.

Backplane Bus Communication Velocity and Dynamic Signal Filtering
The IC200ALG266 executes rapid dynamic data conversion, relying on internal backplane bus communication velocity protocols to present updated 15-bit channel values to the main processor every 7.5 ms. The input stage utilizes internal active signal filtering with a 3dB corner frequency response tuned between 24 Hz and 32 Hz to reject high-frequency field noise. Integrated protection circuits safeguard the channel inputs against continuous overvoltage conditions up to 30 VDC and clamp accidental direct 24 VDC connections to a maximum current limit of 40 mA.
Frequently Asked Questions
Q: Does the IC200ALG266 module supply 24 VDC loop power directly to external 2-wire field transmitters?
A: No. The module operates entirely on logic-side power derived from the VersaMax 5 VDC backplane bus (drawing up to 150 mA) and does not contain an internal field loop power supply. Connected 2-wire field transmitters require an external 24 VDC power supply wired in series with the current loop.
Q: How does the module handle an open-wire condition when configured for 4-20 mA current mode?
A: When operating in 4-20 mA input mode, the module continuously monitors loop integrity. If field wiring breaks and input current drops below the valid operating threshold, the hardware reports an open-wire fault diagnostic flag to the CPU and updates the module status registers.
Q: Is channel-to-channel isolation supported across the 15 input terminals?
A: No. The 15 input channels are arranged in a single-ended wiring configuration sharing a single common return path. Galvanic isolation rated at 250 VAC continuous (1500 VAC for 1 minute) is provided between the field-side input group, backplane logic, and frame ground.
Field Installation Guidelines
- Baseboard Installation: Align the rear interface connector with the VersaMax I/O carrier slot and press the module firmly onto the baseboard until the retention latches snap into place.
- Jumper Range Selection: Set the onboard hardware jumpers prior to mounting to select between 4-20 mA and 0-20 mA current acquisition modes according to site requirements.
- Signal Cable Shielding: Route all 4-20 mA input loops using shielded twisted-pair conductors. Ground the cable shield drain wires at a single point on the enclosure grounding bar to prevent stray ground currents.
- Wiring Separation: Maintain a minimum physical separation between 4-20 mA signal wiring runs and high-voltage AC power cables within cabinet wiring trunks to prevent electromagnetic interference.
- System Grounding: Ensure the DIN rail or enclosure mounting panel maintains a low-impedance connection to protective earth ground to establish a proper noise dissipation path for module isolation barriers.
