GE Fanuc IC670ALG310 Field Control 8-Channel Analog Voltage Output Module

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The GE Fanuc IC670ALG310 is an 8-channel analog voltage output module designed for the Field Control distributed I/O architecture. It converts digital control commands from a host controller or Bus Interface Unit (BIU) into precision -10 VDC to +10 VDC voltage signals to drive variable speed drives, control valves, and analog positioning devices.

Because Emerson discontinued the legacy Field Control series, securing this module as New Surplus prevents extended production line halts. Procuring genuine unused inventory eliminates the high failure rates associated with aged components while reducing Total Cost of Ownership (TCO) during last-time-buy platform transitions.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

Isolate all external 24 VDC field power supplies attached to the terminal base. Wear an ESD grounded wrist strap to prevent static discharge into the backplane circuitry. Document DIP switch positions and node configuration on the adjacent Bus Interface Unit before removing the existing module.

Stage 2: Removal

Unlock the side retaining latches on the terminal block housing. Pull the IC670ALG310 module straight outward off the terminal base, applying balanced force to prevent bending the backplane connector pins.

Stage 3: Installation (Clone & Seat)

Align the replacement module’s edge guide with the slot on the IC670CHS terminal block base. Press the module inward until the locking tabs snap securely into place. Verify that keying pegs match the base configuration.

Stage 4: Power-On & Testing

Re-apply 24 VDC external power. Check that the front panel LED lights green. Use a Hand-Held Monitor (HHM) or host programming software connected to the BIU to verify channel configuration and test output voltage levels at the terminals with a digital multimeter.

Firmware/Software Versions & Upgrade Notes

• BIU Compatibility: The IC670ALG310 requires a Genius Field Bus Interface Unit (BIU) running Revision 2.0 or higher for proper module configuration and scaling.
• Configuration Protocol: Unlike standard digital modules, the IC670ALG310 must be configured directly via the BIU or a compatible Hand-Held Monitor (HHM) to set active/inactive channel states and output scaling parameters.
• Firmware Risks: Replacing a module on a live BIU bus segment without matching host configuration tables can cause communication timeouts or force outputs into fault-state hold modes.

Frequently Asked Questions (FAQ)

1. Is this IC670ALG310 module genuine New Surplus or a refurbished part?

This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.

2. What are the operational risks of using refurbished analog output modules?

Refurbished analog modules often suffer from thermal drift, worn output operational amplifiers, and degraded internal voltage references that cause calibration errors. A chemical plant recently tried to save procurement budget by buying a refurbished DCS I/O module. Three months later, it failed, causing a reactor temperature fault and an emergency shutdown. The downtime cost was 10x what they “saved.”

3. Has the GE Field Control series been retired by the manufacturer?

Yes, Emerson (who acquired GE Intelligent Platforms) has discontinued the Field Control line. Purchasing New Surplus stock is the primary method to maintain active systems without undertaking expensive control system re-engineering.

4. Can I hot-swap the while the terminal base is powered?

Although Field Control terminal bases support mechanical insertion, best practice requires disconnecting external field supply voltage before extracting the module. Removing analog modules under load can cause signal spikes on adjacent channels or damage driven actuators.

5. Does the retain its channel configuration when power is removed?

No. Channel scaling parameters, alarm limits, and active channel states are stored in and managed by the host Bus Interface Unit (BIU). When a new module is seated, the BIU downloads the configuration data to the module during initial handshake.

6. What terminal block base does this module plug into?

The installs into standard Field Control I/O terminal bases, such as the IC670CHS101 barrier style or IC670CHS001 box terminal bases.

7. What warranty coverage comes with this module?

Every New Surplus is covered by a 1-2 year warranty, providing full long-term protection compared to the typical 30-day warranty offered on used or repaired parts.
