GE IC694ALG442 PACSystems RX3i Analog Current/Voltage Combination Module

Frequently Asked Questions (FAQ)

Q1: What types of signals can the IC694ALG442 module handle?
A1: It supports both analog current (0–20 mA, 4–20 mA) and analog voltage (0–10 V, ±10 V) signals.

Q2: Can the input channels be configured independently?
A2: Yes, each input channel can be individually configured as current or voltage.

Q3: What is the resolution for the analog inputs and outputs?
A3: Input resolution is 5 µA or 2.5/5 mV; output resolution is 0.3125 mV or 0.5/0.6 µA depending on range.

Q4: Is there isolation between the field side and backplane?
A4: Yes, 250 VAC continuous and 1500 VAC for 1 minute.

Q5: Does this module support alarm configurations?
A5: Yes, each input can be configured with high and low alarm limits.

Q6: What happens to the outputs on power loss?
A6: Outputs can be configured to hold the last state or reset to the low end of their configured range.

Q7: What is the function of the ramp mode?
A7: Ramp mode enables smooth transitions between output values over a configured time or steps.

Q8: Is the firmware upgradable?
A8: Yes, but only when used in RX3i racks, not in Series 90-30 systems.
