Allen-Bradley 1734-IB8S

Product identity

Product overview

The 1734-IB8S is the eight-input POINT Guard I/O safety input reference. The OEM specification lists current-sinking safety inputs and a nominal 24 V DC power bus. It is a different identity from the standard 1734-IB8, even though both have eight inputs. Application acceptance depends on the installed safety system, device configuration and validation requirements. This page identifies the requested module and provides sourcing checks; it does not establish a machine safety rating or approve a replacement.

Before requesting this part

Preserve the S suffix and provide the module series, firmware information and existing safety-controller/station details. Record the terminal base, safety-device wiring, test-pulse arrangement and configured application. Have the responsible engineer review the exact module documentation and the required safety validation before accepting an alternative or recommissioning a replacement. Request actual-unit identity photos, declared condition and a written test scope. Keep any proposed standard IB8, coated variant or different revision separate from the original requirement. Include quantity, destination, required date and the documentation needed for the offered unit.
