IC698CHS009 | GE Fanuc Rx7i PACsystem | I/O Rack

Product Overview

The GE IC697VAL314 is a 4-Channel Isolated Analog Output Module for the GE Fanuc Series 90-70 PLC platform. It provides high-accuracy analog current output for controlling field devices such as valve positioners, variable frequency drives (VFDs), and actuators. With 12-bit resolution, channel-to-channel isolation, and a removable terminal block, this module delivers reliable signal integrity and easy maintenance in demanding process control applications. Note: This module has been discontinued by GE with no direct replacement; it remains available through authorized surplus and refurbishment channels.

Features & Benefits

• High Isolation: 1500V RMS channel-to-channel isolation prevents ground loops and noise coupling
• 12-Bit Resolution: Provides precise analog control for fine-tuned process adjustments
• Removable Terminal Block: Simplifies wiring and module replacement without disturbing field connections
• Flexible Ranges: Supports 4–20 mA, 0–20 mA, and 5–25 mA to match diverse actuator requirements
• Strong Load Drive: 750 Ω capability allows driving multiple series-connected devices or long cable runs

Applications

• Process valve positioner control in chemical plants
• VFD speed reference signals in HVAC and pumping systems
• Pressure and flow control loop actuation
• Building automation damper and valve control
• Legacy Series 90-70 system maintenance and expansion

Installation Guide

1. Power Down: Turn OFF rack power before installing or removing the module
2. Slot Insertion: Insert the IC697VAL314 into any available I/O slot on the Series 90-70 rack
3. Terminal Block Wiring: Connect field devices to the removable terminal block — IOUT+ and IOUT− per channel
4. Shielding: Use shielded twisted-pair cable for analog output wiring; ground shield at one end only
5. Configuration: In Proficy Machine Edition or VersaPro, configure each channel for the desired output range (4–20 mA, 0–20 mA, or 5–25 mA)
6. Scaling: Set output scaling in the PLC program to match engineering units (e.g., 0–100% = 4–20 mA)
7. Verification: Power up and verify output current with a calibrated multimeter at the terminal block

FAQ

Q: Is the IC697VAL314 still in production?
A: No, GE has discontinued this module with no direct replacement. It is available through surplus, refurbished, or third-party industrial automation suppliers.

Q: Can I use this module for voltage output?
A: The IC697VAL314 is a current output only module. For voltage output (0–10V), consider the IC697VAL318 or other VME-based analog output boards.

Q: What is the maximum loop resistance?
A: Each channel can drive up to 750 Ω, which is sufficient for most 4–20 mA loops including long cable runs and series-connected indicators.

Q: How do I calibrate the outputs?
A: The module is factory-calibrated. If recalibration is needed, refer to the GFK-2057 manual for the analog output board calibration procedure using precision voltage and current standards.

Selection Tips

• Since this module is discontinued, verify supplier warranty and testing procedures before purchase
• For new projects, migrate to RX3i IC695ALG708/808 analog output modules for modern support
• Ensure your Series 90-70 power supply can supply 125 mA @ 5VDC per module
• When replacing a failed VAL314, check adjacent modules for overvoltage damage that may have caused the failure
• Consider stocking a spare unit if you have multiple VAL314s in service — availability will decline over time
