ABB GJR5251400R3202 07 DC 91 Advant Controller 31 I Unit

ABB GJR5251400R3202 is an Advant Controller 31 I/O Unit (model type 07DC91) that functions as a digital input block for ABB's Advant Controller 31 automation system, interfacing 24 V DC field signals from sensors, pushbuttons, and limit switches to the central controller over the CS31 bus, and enabling reliable, high‑speed input conditioning within industrial control panels. The module's footprint is 140 mm wide by 85 mm high by 120 mm deep, it weighs approximately 0.12 kg, and ABB documentation specifies a front‑panel height/depth of 85 mm with installation depth considerations for DIN rails, meaning extra space is needed to accommodate mounting hardware. Its input signaling is specified for 24 V DC operation in the 0–24 V range, aligning with common industrial sensors, and the part number GJR5251400R3202 identifies it as the Advant Controller 31 I/O Unit with the 07 DC 91 designation used on ABB's catalog pages. Typical applications include expanding the controller's digital input capacity for monitoring machine states, interlocks, start/stop signals, conveyor sensors, and other field devices in automation environments that rely on ABB's Advant Controller 31 ecosystem.
