Description Reviews

The GE IC694ALG391, also cataloged as the IC694ALG391 Analog Output Module, operates as a dedicated hardware component for field signal generation within PACSystems RX3i platforms. The unit converts internal controller logic values into 2 channels of analog current or voltage signals (1-5 VDC, 0-5 VDC, 0-20 mA, or 4-20 mA) using a 12-bit digital-to-analog converter.

Backplane Bus Interfacing and Deterministic Networks

The IC694ALG391 module interfaces directly with the PACSystems RX3i backplane bus to transfer command values from the CPU to its onboard digital-to-analog conversion circuits. Utilizing high backplane bus communication velocity, output values update deterministically during each controller scan cycle. Built-in firmware flash compatibility preserves system messaging integrity and ensures synchronized signal updates across expanded local or remote RX3i baseplate racks.

Frequently Asked Questions

Q: What output signal ranges can be configured on the IC694ALG391?

A: The module supports software configuration for both voltage (1-5 VDC, 0-5 VDC) and current (0-20 mA, 4-20 mA) field outputs across its 2 channels.

Q: How is the IC694ALG391 physically mounted in a system?

A: The module installs directly into any standard single slot of an RX3i baseplate, which supports panel or DIN rail chassis mounting inside an industrial enclosure.

Q: What resolution does the internal D/A converter provide for field control signals?

A: The onboard digital-to-analog converter operates at a 12-bit resolution across all configured voltage and current ranges.

Field Installation Guidelines

Disconnect main backplane rack power and field loop power sources before inserting or removing the module.
Fasten an ESD wrist strap to a grounded metal enclosure framework prior to handling the module assembly.
Align the module with the card guides of the target RX3i baseplate slot and press firmly until the locking tab fully engages.
Wire output field devices using shielded twisted-pair cables, grounding the cable shield drain wire at a single point near the enclosure earth terminal.
Apply system power and confirm through status LEDs that the card undergoes initialization without channel fault reports.
