GE IC697ALG320 4-Channel Analog Output Module for Series 90-70 and PACSystems Backplanes

Applications

The IC697ALG320 module is ideal for applications where precise analog outputs are required in process and machine control systems:

• Flow, pressure, and temperature control loops

• Distributed analog control in manufacturing automation

• Actuator and valve position control

• Analog signal generation for servo drives and motor control

• Integration with supervisory loop systems

Its flexible output types and software configurability make it suitable for hybrid control architectures that mix analog and digital I/O. 

Advantages

• Dual signal output flexibility — supports both voltage and current on each channel.

• High resolution and precision — 16-bit conversion ensures fine output granularity.

• Software configurability — no DIP switches or jumpers required; easy setup through PLC tools.

• Factory calibration with EEPROM storage — long-term stability without manual re-tuning.

• Strong isolation and protection — reduces susceptibility to backplane noise and transients.

• Robust industrial design — suitable for continuous operation in 24/7 environments.

These features help ensure accurate analog control signal generation, enhance system responsiveness, and simplify commissioning and maintenance tasks.

Technical FAQs

1. What is the main function of the IC697ALG320?
It converts digital data from the PLC into analog voltage or current outputs for field devices.

2. How many output channels does it support?
It offers four independently configurable analog output channels.

3. What output ranges are supported?
Voltage outputs from –10 V to +10 V and current outputs up to 0–22.5 mA (4–20 mA default).

4. What is the resolution of the outputs?
16-bit resolution with 14-bit monotonicity.
