Product Overview

The GE Fanuc IC697VAL318 is an 8-channel isolated analog output module engineered for the Series 90-70 PLC platform. This module is designed to convert digital control data from the PLC backplane into precise 4-20 mA current signals, providing reliable control for industrial actuators, valves, and variable frequency drives. Its robust design is well-suited for demanding process control applications, including chemical manufacturing, water treatment, and power generation, where signal integrity and system protection are essential.

Features

• High-Resolution Control: Utilizes 12-bit resolution to ensure fine-grained adjustment of connected field devices.
• Galvanic Isolation: Equipped with channel-to-backplane isolation to prevent ground loops and protect the PLC processor from electrical noise and surge events.
• Channel Density: Provides eight independent output channels, allowing for efficient control of multiple process loops within a single slot.
• Field Maintenance: Features a removable terminal block design that allows for rapid module replacement and field wiring access without the need to disconnect permanent field cabling.

Technical Specifications

Installation Guidelines

• Safety First: Always disconnect power from the Series 90-70 rack before inserting or removing the module to prevent electrical damage or unexpected system behavior.
• ESD Precautions: Handle the module by its edges or the front faceplate to avoid electrostatic discharge damage to sensitive internal components.
• Grounding: Ensure the rack and backplane are properly grounded according to site specifications to maintain the effectiveness of the module's isolation features.
• Wiring: Use shielded twisted-pair cabling for 4-20 mA loops to minimize potential electromagnetic interference (EMI) in high-noise industrial environments.
• Ventilation: Maintain proper airflow within the PLC cabinet to ensure the module operates within its specified 0 to 60 degC temperature range.

FAQ

What is the primary function of the IC697VAL318?
This module acts as a digital-to-analog interface for the GE Fanuc Series 90-70 system, translating digital control signals into 4-20 mA current outputs for field instrumentation.

Does this module require external power for the loops?
The IC697VAL318 is designed for integration within the Series 90-70 backplane. Consult your specific system wiring diagrams to determine if your field devices require a separate loop power supply.
