Configured for high-resolution single-ended analog current signal processing in VersaMax I/O architectures, the GE Fanuc IC200ALG262 (IC200ALG262 Analog Input Module) provides direct physical/electrical execution. The module converts 0-20 mA or 4-20 mA current loops across 8 single-ended input channels arranged in a single group, delivering digitized values directly to the central processing unit or network interface unit over the backplane bus.

Backplane Bus Communication Velocity & Firmware Flash Compatibility
The module executes backplane data transfers at deterministically scheduled scan cycles, updating all 8 analog channel values every 7.5 ms across the 5 VDC VersaMax system bus. Integrated Analog-to-Digital Converter (ADC) logic guarantees a constant 15-bit digital resolution across both 0-20 mA and 4-20 mA operating modes without processing overhead. Full backplane communication and configuration execution requires compatibility with VersaPro software Version 2.0 or higher, VersaMax PLC CPU Firmware 2.10 or higher, or Ethernet Network Interface Unit (NIU) firmware Version 1.10 or higher. Range selection relies on hardware jumpers: operating without a terminal jumper sets the default 4-20 mA range, whereas installing the jumper selects the 0-20 mA range.
Frequently Asked Questions
Q: What are the firmware requirements for operating the IC200ALG262 with a VersaMax CPU or NIU?
A: The module requires VersaMax PLC CPU Firmware Version 2.10 or higher, or VersaMax Ethernet NIU Firmware Version 1.10 or higher, used alongside VersaPro software Version 2.0 or higher.
Q: How is open wire fault detection handled across the input ranges?
A: Open wire fault detection is active exclusively when the module is operating in the 4-20 mA range mode; loss of internal power diagnostics remains active across all modes.
Q: What is the maximum current drawn by the module from the backplane?
A: The module draws a maximum current of 200 mA from the internal 5 VDC system backplane power supply.
Field Installation Guidelines
- Snap the module securely onto the VersaMax I/O backplane carrier or DIN rail assembly before applying system power.
- Ensure terminal jumpers are installed or removed on the wiring base prior to field wiring according to the desired loop range (uninstalled for 4-20 mA, installed for 0-20 mA).
- Connect 8 single-ended field current loops using shielded twisted-pair cables to mitigate common-mode noise and external electromagnetic interference.
- Connect cable shields to ground at the signal source end, or ground at the module base if source grounding is unavailable.
- Verify that the module OK LED illuminates green upon power-up to confirm valid backplane initialization and successful configuration loading.
