Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The 900C31-0011 is the device-level element in a Honeywell PLC controller installation. It receives the field signals and control supply listed above — 24 V DC (IEC 61131-2) — and switches or conditions the load within the the rated ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in packaging machines, conveyor transfer cells, small process skids, where the unit is matched to the original catalog number and the enclosure provides 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Honeywell 900C31-0011
Honeywell 900C31-0011 — PLC / CPU module used as the device-level control core in an automation panel, handling logic, timing and communication tasks. The figures below are taken from the specification table on this page for catalog number 900C31-0011; record the nameplate data of the unit being replaced before selecting an equivalent.
- Supply voltage: 24 V DC (IEC 61131-2) — Check this value against the nameplate of the installed unit before ordering.
- Operating temperature: 0...+55 °C (IEC 60068-2-1) — Match it to the existing panel and upstream protection.
- Communication ports: 1 Ethernet port, 10/100 Mbps — Record it with the other nameplate data when sourcing a replacement.
- Dimensions (H x W x D): 137 mm x 38.1 mm (5.4 in x 1.5 in) — Confirm the revision of the installed unit before a like-for-like replacement.
