GE Fanuc IC693ALG221 4-Channel Analog Current Input Module

Description
GE Fanuc IC693ALG221 is a 4-channel analog current input module for Series 90-30 PLCs, supporting 4–20 mA and 0–20 mA input ranges with 12-bit resolution.

Features

• 4 isolated analog current input channels
• Dual input ranges: 4–20 mA (default) and 0–20 mA (jumper selectable)
• Independent jumpers for channels 1–2 and 3–4
• 12-bit resolution with 16-bit 2’s complement output format
• Optical isolation to reduce electrical noise
• LED indicator for power status
• Compatible with Series 90-30 baseplates (5 or 10-slot)
• Self-diagnostic for reversed current input (outputs low-range data)
