GE IC695ALG106-AA PACSystems RX3i Isolated Analog Input Module Original

Frequently Asked Questions (FAQ)

What types of input signals does the IC695ALG106-AA support?
It supports both current (0–20mA, 4–20mA, ±20mA) and voltage (±10V, 0–10V, ±5V, 0–5V, 1–5V) input signals.

Can this module be used without an external 24VDC power source?
No, it requires an isolated external +24 VDC power supply connected via the TB1 connector.

How is signal isolation handled between channels and the backplane?
Each channel is isolated via I-coupler and transformer methods, offering 250 VAC continuous or 1500 VAC for 1 minute.

What digital filtering options are available for noise reduction?
Six digital filter frequencies are available: 8Hz, 12Hz, 16Hz, 40Hz, 250Hz, and 1000Hz.

How often does the module update its input readings?
It provides a new analog sample every 1 millisecond regardless of the selected filter.

Is there any built-in diagnostics for detecting faults on channels?
Yes, it can detect open wires, over-range, under-range, short circuits, and alarm thresholds.

Does this module require calibration?
Typical calibration interval is 12 months to maintain accuracy. Offset can be adjusted periodically.

What happens if the terminal block is not properly seated?
The module will indicate a red LED (TB indicator) and disable channel operations until reconnected correctly.
