The GE IC695ALG106, also cataloged as the IC695ALG106 Isolated Analog Input Module, operates as a dedicated hardware component for multi-channel analog signal acquisition and digital conversion within GE PACSystems RX3i platforms. Configured with 6 individually isolated channels, this unit provides direct physical/electrical execution to convert current (0-20 mA, 4-20 mA, +-20 mA) and voltage (+-10 V, 0-10 V, +5 V, 0-5 V, 1-5 V) inputs using a 16-bit ADC architecture.

Backplane Bus Interfacing and Deterministic Communications

The IC695ALG106 module mounts directly into an RX3i Universal Backplane slot to interface with the central processing unit over high-speed PCI backplane paths. Backplane bus communication velocity allows rapid transfer of 32-bit floating point or 16-bit integer data frames during every backplane scan cycle. Firmware flash compatibility across the RX3i platform ensures synchronized signal timing and deterministic networks execution across local and expansion racks. Channel-to-channel isolation eliminates cross-talk noise and ground loop currents across all six field signal loops.

Frequently Asked Questions

Q: How does the IC695ALG106 module protect field signal lines from electrical noise across channels?

A: Each of the 6 input channels features individual electrical channel-to-channel isolation, preventing ground loops and cross-talk interference between field devices.

Q: What power draw does the IC695ALG106 module exert on the RX3i backplane supply?

A: The module draws 230 mA from the 5 VDC bus line and 320 mA from the 3.3 VDC bus line, with a maximum power dissipation of 2.97 W.

Q: Which terminal block options are compatible with this module?

A: Field wiring connects via compatible RX3i terminal blocks including models IC694TBB032, IC694TBB132, IC694TBS032, and IC694TBS132.

Field Installation Guidelines

  1. De-energize the host RX3i Universal Backplane rack before installing or removing the IC695ALG106 module.
  2. Put on an anti-static wrist strap anchored to cabinet ground to prevent ESD damage during module insertion.
  3. Align the module circuit card with the chosen backplane slot track and press firmly until the module latches securely into the backplane.
  4. Wire field instrumentation to the compatible terminal block (IC694TBB/TBS series), taking care to maintain polarity for voltage and 4-20 mA current loops.
  5. Secure the terminal block assembly onto the module front housing and ground all cable shield braidings at the designated rack grounding bar.
