ABB 07DI92, order number GJR5252400R0101, is a CS31 remote digital-input module with 32 inputs for 24 V DC signals. The inputs are arranged as four groups of eight, with group-to-group isolation and isolation from the remainder of the unit. The module itself uses a 24 V DC supply and occupies two digital input addresses on the CS31 system bus.
The documented logic-zero interval is −30 to +5 V and the logic-one interval is +13 to +30 V. Typical input delay is 7 ms and typical input current is 7 mA at 24 V. These figures define the sensor-interface review: the input voltage, available sensor drive and off-state leakage must be checked together, particularly for electronic proximity sensors and long field wiring.
For a maintenance replacement, retain the installed addressing and terminal allocation, verify the four input-reference connections and preserve the control-system grounding arrangement. The module needs no stored I/O configuration data, but the controller project and hardware address must still agree. Supplier acceptance should identify the complete GJR order number, count the removable terminal blocks and test the required input points against the original wiring schedule.

Preserve the CS31 address allocation, input-reference wiring and grounding plan before replacing the module.
It lies between the documented logic-zero and logic-one bands. Do not use it as a guaranteed state in an acceptance test. Investigate sensor drive, voltage drop and leakage, then restore a signal level within the specified band.
Measure the actual input voltage relative to its group reference with the sensor off, and compare the sensor’s leakage specification with the module input characteristics. The off state must remain within the documented zero band; an unloaded sensor voltage alone does not prove compatibility.
No. The manual separates a maximum module current consumption of 0.15 A from a maximum 4.0 A load rating for the supply terminals. Use the former for module demand and the latter as a terminal-loading limit; neither is a digital-output rating.
No. The −30 V lower limit describes the signal-input zero range, not a permissible reversed operating supply. Wire the nominal 24 V DC module supply to its designated polarity and follow the grounding drawing.
The manual describes all LEDs being on during automatic initialization. A brief startup illumination is therefore different from 32 confirmed active process inputs. Evaluate field states after initialization and verify them in the controller.
The manual states that the error LED flashes when the CS31 system bus is not running. Check the bus master, bus wiring and communication state rather than assuming the indication identifies a faulty individual input sensor.
The stated delivery scope includes one 5-pole block and one 3-pole block at 5.08 mm pitch, plus four 10-pole blocks at 3.81 mm pitch. Check that the offered spare includes the agreed pieces and that their pitch and terminal condition match.
No. 07DI92 is a digital-input module and requires no I/O configuration data internally. It is not the configurable 07DC92 I/O module. Confirm the installed hardware identity when a spare request describes bidirectional channels.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
