GE IC693ALG392B High Density Analog Current/Voltage Output Module

FAQ

Q1: What is the GE Fanuc IC693ALG392B used for?
The IC693ALG392B is used in Series 90-30 PLC systems to generate analog output signals for controlling field devices such as actuators, control valves, VFDs, and other modulating equipment.

Q2: How many analog output channels does the IC693ALG392B provide?
The module provides 8 single-ended analog output channels, with each channel configurable for voltage or current operation.

Q3: What output signal ranges are supported by the IC693ALG392B?
The module supports voltage outputs of 0 to +10 VDC and -10 to +10 VDC, as well as current outputs of 0–20 mA and 4–20 mA.

Q4: What is the resolution of the IC693ALG392B?
The module provides 15–16 bit resolution, depending on the selected output range. Current output resolution is approximately 0.5 µA per count for 4–20 mA and 0.625 µA per count for 0–20 mA.

Q5: Does the IC693ALG392B require an external power supply?
Yes. The module requires an external isolated 20–30 VDC supply for analog output operation, while the PLC backplane provides the internal 5 VDC operating power.

Q6: What devices can be connected to the IC693ALG392B outputs?
The module can be connected to industrial devices such as proportional valves, motor drives, controllers, signal converters, data recorders, and other analog-controlled equipment.

Q7: Does the IC693ALG392B provide diagnostic functions?
Yes. When operating in current output mode, the module can detect and report open-wire faults for individual output channels to the PLC CPU.

Q8: What should be checked before replacing an IC693ALG392B module?
Before replacement, check the Series 90-30 rack compatibility, external 24 VDC power supply, analog output configuration, terminal wiring, load requirements, PLC hardware configuration, and channel scaling parameters to ensure proper operation after installation.
