Description Reviews

The GE IC694ALG390, also cataloged as the IC694ALG390 Analog Output Module, operates as a dedicated hardware component for bipolar analog voltage output generation within RX3i PACSystem backplane networks. The module converts digital control words into two independent voltage channels spanning -10 VDC to +10 VDC at 2.5 mV resolution and a 5 ms conversion update rate.

Backplane Bus Interfacing and Deterministic Networks

The IC694ALG390 interfaces directly with the PACSystems RX3i backplane, maintaining determinism across high-speed process loops. Module execution leverages backplane bus communication velocity to pull digital values from the CPU and update both physical voltage outputs within 5 ms. Operating in tandem with RX3i power distribution, the module isolates field-side power (18 VDC to 30 VDC) from logic-side backplane draw (32 mA at 5 VDC). High-density I/O density scaling and firmware flash compatibility enable synchronized channel execution across multi-rack RX3i architectures without degradation of signal accuracy.

Frequently Asked Questions

Q: What are the external power supply requirements for the IC694ALG390 analog output module?

A: The module requires an external user supply between 18 VDC and 30 VDC, drawing up to 120 mA with a maximum allowable voltage ripple of 10%.

Q: What is the capacitive load limitation on the voltage output channels?

A: Each analog output channel can drive a field load with a maximum output load capacitance of 2000 pF.

Q: How does the module indicate active operational or fault status?

A: Status updates and channel activity are indicated visually in real time via front-panel LED indicators.

Field Installation Guidelines

Disconnect backplane system power and external 24 VDC field supplies prior to inserting or removing the module from the RX3i rack.
Wear an ESD grounding wrist strap attached to an unpainted enclosure ground point during installation.
Align the module housing with the target RX3i backplane slot guide rails and push firmly until the rear connector seats into the backplane.
Wire field output loops to the module ports, ensuring cable shielding is grounded at one end only to suppress signal noise.
Apply external 18-30 VDC power and verify that the front-panel status LEDs indicate normal operation without fault conditions.
