Find a replacement by catalog number
Allen-Bradley 1734 POINT I/O Parts
Start with the complete catalog number on your module or adapter. POINT I/O includes network adapters, standard digital I/O, analog I/O and safety I/O. The terminal base and network are separate selection decisions; matching the 1734 prefix alone is insufficient for a replacement.
Before choosing a replacement
Match the network adapter
1734-AENTR uses EtherNet/IP, 1734-ACNR uses ControlNet, and 1734-ADN uses DeviceNet. Include the installed network and required hardware series in your enquiry. A network change needs engineering review.
Separate standard and safety I/O
1734-IB8 is a standard input module; 1734-IB8S is a safety input module. Confirm the complete suffix, application requirements and terminal base before choosing a replacement.
Check signal direction and channel count
1734-OB8 provides digital outputs. 1734-OE2C and 1734-OE4C provide two and four analog current outputs respectively. Include the signal type and channel count when requesting a part.
