Product Description
The GE Fanuc IC670ALG310-LA, also cataloged as the IC670 Analog Output Module, operates as a dedicated hardware component for continuous variable voltage signal generation within Field Control I/O stations. The sub-assembly drives 8 single-ended voltage outputs natively at the hardware tier to actuate industrial process control positioning elements, speed regulators, and chart recording instrumentation across modular expansion frameworks.

Industrial Control & Drive Communications
- Backplane Bus Communication Velocity and Processing Matrix The internal Digital-to-Analog Converters (DAC) process digital registers scaled in engineering units received from the local Bus Interface Unit (BIU) via the passive parallel backplane structure. The interface circuitry parses incoming data words, matches them with local configuration parameters, and updates all 8 analog channel voltage tracks within a typical 1.5 ms execution window to preserve deterministic process loop control velocities.
- I/O Density Scaling and Output Voltage Leveling The 8-channel hardware block handles multi-point analog outputs from a single terminal base footprint. The output stages are engineered to hold stable potential registers across a broad bipolar range from -10.25 VDC to +10.25 VDC, balancing signal accuracy against varying thermal profiles inside the unventilated local chassis enclosure.
Frequently Asked Questions
Q: What are the installation hazards associated with routing voltage outputs below the 5000 Ohms load minimum?
A: Connecting an external device with an internal impedance below 5000 Ohms pulls current from the module output buffers in excess of their physical thermal design limits. This overload degrades output linearity, drops loop accuracy past the 0.15% specification, and risks burning out the output channel drivers.
Q: How does ripple voltage on the external power supply affect the module output accuracy?
A: Ripple variations exceeding the 5% maximum constraint penetrate the internal regulation filters of the sub-assembly. This injects periodic noise into the reference voltage rails of the DAC, generating high-frequency output signal oscillations that can destabilize high-speed actuator control loops.
