Description

The GE Fanuc IC697ALG320 is a high-performance analog output module designed for use within the Series 90-70 PLC system. This module provides four isolated output channels capable of delivering both voltage and current signals to field devices. It is engineered to support precision control applications, offering 16-bit resolution with 14-bit monotonicity to ensure accurate signal output for complex industrial processes.

Features

• Four independent analog output channels.
• Supports configurable voltage ranges (-10V to +10V) and current ranges (0-20mA or 4-20mA).
• High-resolution output with 312.5 microvolts per LSB step in voltage mode.
• Fast conversion rate of 2.0 milliseconds.
• Requires external user power supply for current output functionality.
• Occupies a single slot in the Series 90-70 rack system.

Installation Guidelines

• Ensure the PLC rack is powered down before inserting or removing the IC697ALG320 module to prevent electrical damage.
• Verify that the external 24 VDC power supply is correctly wired to the module terminals for current output operation.
• Maintain proper grounding practices for all shielded signal cables to minimize electromagnetic interference (EMI).
• Ensure the rack environment provides adequate ventilation to dissipate the 8.3-watt power load generated by the module.
• Limit installation to a maximum of seven IC697ALG320 modules per rack to stay within power and backplane capacity constraints.

FAQ

What is the primary function of the IC697ALG320?

This module serves as an analog output interface for the GE Series 90-70 platform, converting digital values from the PLC processor into proportional voltage or current signals for external instrumentation, valves, or actuators.

Does this module require external power?

Yes, while the module draws logic power from the backplane, an external 10-30 VDC user supply is required to drive the current output loops.

Is this module still in production?

No, the IC697ALG320 has been discontinued by the manufacturer. We provide these units from our surplus inventory to support legacy system maintenance.
