The Allen-Bradley 1734-IB8S is a POINT Guard I/O safety digital input module designed to monitor safety devices and communicate safety input data through CIP Safety networks. It is intended for use within a configured industrial safety architecture.
Monitors emergency-stop input circuits as part of a configured machine safety function.
Receives safety status from guard-door and interlocking switch circuits.
Monitors safety sensor signals used to protect machine access and operating areas.
Typical sourcing triggers include a safety input channel fault, an input circuit that remains OFF, wiring or test-pulse diagnostic errors, or a module that no longer reports the expected safety input status. If the affected safety circuit cannot be validated, the machine may be unable to complete its safety reset or resume production, resulting in unplanned downtime.
Electrical, input, test-output and POINTBus data from the Rockwell Automation POINT I/O selection guide.

Rockwell identifies 1734-AENT (firmware revision 3 or later) and 1734-AENTR for EtherNet/IP architectures, and 1734-PDN for DeviceNet architectures. The manual lists 1734-ADN, 1734-ADNX, 1734-APB and 1734-ACNR as incompatible adapters for POINT Guard I/O safety communications. Confirm the installed adapter, controller, firmware and safety configuration before replacement.
The manual describes single-channel use up to PLd / SIL CL2 when the channel is configured for Safety Pulse Test.
The manual describes dual-channel use up to PLe / SIL CL3 and Category 3 or 4 when both channels use Safety Pulse Test configuration.
When an input error is detected, safety input data remains OFF. The documented recovery sequence is to remove the error cause, place the safety input into its safe state, and allow the input-error latch time to elapse. The red I/O indicator turns off after the recovery conditions are met.
Safety ratings are conditional on the specified channel configuration and the complete safety system. They are not a standalone guarantee of machine-level performance.
Rockwell's product listing specifies compatibility with terminal bases having eight terminations.
Check wiring, module configuration, firmware revision, safety network addressing and trial operation before returning the system to service.
The manufacturer's manual identifies emergency-stop push buttons, gate switches and safety light curtains as examples of safety devices.
Yes. Its documented input modes include single-channel and dual-channel configurations. The applicable safety rating depends on the configuration and complete safety system.
POINT Guard I/O safety communication is documented over EtherNet/IP and DeviceNet through supported network adapters.
Confirm the full catalog number, terminal base, network adapter, controller, firmware, wiring arrangement and safety input configuration before installation and commissioning.
For engineers searching for a 1734-IB8S pdf/manual/datasheet, the relevant Rockwell Automation publications include the POINT Guard I/O Safety Modules User Manual (1734-UM013) and the POINT I/O Modules Selection Guide (1734-SG001).
