GE Fanuc IC697ALG320 4-Channel Analog Output Module Series 90-70

GE Fanuc IC697ALG320 Analog Output Module

GE Fanuc IC697ALG320 is a 4-channel analog output module for Series 90-70 PLC architecture. Each channel configures independently for voltage (±10V) or current (4-20mA) signals. Features software-driven jumperless design, onboard EEPROM calibration, and 0.85kg compact form factor.

Technical Specifications

Core Technical Advantages

Software-Driven Jumperless Architecture
No manual hardware jumpers or DIP switches. All configuration assignments are defined entirely through programming software, simplifying field commissioning and eliminating manual setup errors.

Integrated Non-Volatile Memory Calibration
Each channel undergoes factory calibration with constants stored directly in onboard EEPROM. The module references this data during runtime to ensure accurate tracking and protection against signal drift.

Flexible Range and Signal Profiling
Every channel supports mixed signal types within a single module slot. Advanced digital scaling maps raw engineering values directly to physical outputs.

Installation Guidelines

Backplane Insertion: Power off the Series 90-70 rack before installation. Align the circuit card edge with chassis slot guides and lock mechanical latches.

Field Wiring: Maintain separation between low-voltage analog paths and high-voltage AC lines. Ground cable shields at a single point to minimize EMI interference.

Software Configuration: Define signal format, scaling points, and safety fallback preferences for each channel through the PLC configuration utility.

FAQs

Q1. Can I mix voltage and current signals across different channels?
A1. Yes. Each of the 4 channels operates independently. You can configure Channel 1 for 4-20 mA and Channel 2 for ±10V simultaneously without cross-channel interference.

Q2. How does jumperless configuration simplify field replacement?
A2. No physical switches to mirror. Simply remove the failed module and insert a replacement. The CPU automatically pushes the software configuration to the new card upon boot-up, minimizing downtime.

Q3. What happens to outputs when CPU communication fails?
A3. You configure the fallback behavior. Each channel can be set to either hold its last valid output value or force to an off state during a CPU fault condition.
