IC693ALG220 — GE Fanuc Series 90-30 4-Channel Analog Voltage Input Module

The IC693ALG220 provides four differential ±10 V analog voltage inputs for Series 90-30 systems. Each channel converts to 12-bit user data (stored in %AI), with a typical 1 ms per channel conversion and 4 ms overall update. The front-end includes isolation and input filtering (17 Hz) for stable readings in industrial environments. Input impedance is >9 MΩ (voltage mode). Module power consumption is approximately 27 mA from +5 V and 98 mA from the isolated +24 V backplane supply. For 4–20 mA loops you can use the documented 250 Ω shunt method (voltage module + shunt), noting derating/accuracy guidance from the manual.
