Allen-Bradley 1734-IB8

Product identity

Product overview

The 1734-IB8 is an Allen-Bradley POINT I/O digital input module with eight sinking inputs in one group. Its nominal on-state input is 24 V DC. This reference is for the standard IB8 identity; the similarly named 1734-IB8S belongs to POINT Guard safety I/O and must be evaluated as a separate model. When replacing an installed module, match the complete catalog and series markings and record the terminal base and station configuration rather than selecting by channel count alone.

Before requesting this part

Send the complete 1734-IB8 label, series marking, quantity and acceptable condition. Record the adapter, terminal-base model, field sensor type and wiring in the existing POINT station. State whether you need only the electronics module or additional base/terminal parts; these are separate completeness questions for an offer. Review the power budget and configuration before accepting another revision or a proposed substitute. Ask for actual-unit label photos and the agreed inspection or functional test, then specify destination and required date. A listing for IB8S or another input type is a changed identity requiring review.
