GE IC695ALG106-AA PACSystems RX3i Isolated Analog Input Module

Frequently Asked Questions (FAQ)

Q1: What types of input signals does the IC695ALG106-AA support?
A1: It supports both current (0–20mA, 4–20mA, ±20mA) and voltage (±10V, 0–10V, ±5V, 0–5V, 1–5V) input signals.

Q2: Can this module be used without an external 24VDC power source?
A2: No, it requires an isolated external +24 VDC power supply connected via the TB1 connector.

Q3: How is signal isolation handled between channels and the backplane?
A3: Each channel is isolated via I-coupler and transformer methods, offering 250 VAC continuous or 1500 VAC for 1 minute.

Q4: What digital filtering options are available for noise reduction?
A4: Six digital filter frequencies are available: 8Hz, 12Hz, 16Hz, 40Hz, 250Hz, and 1000Hz.

Q5: How often does the module update its input readings?
A5: It provides a new analog sample every 1 millisecond regardless of the selected filter.

Q6: Is there any built-in diagnostics for detecting faults on channels?
A6: Yes, it can detect open wires, over-range, under-range, short circuits, and alarm thresholds.

Q7: Does this module require calibration?
A7: Typical calibration interval is 12 months to maintain accuracy. Offset can be adjusted periodically.

Q8: What happens if the terminal block is not properly seated?
A8: The module will indicate a red LED (TB indicator) and disable channel operations until reconnected correctly.
