BFKK 1734-IB8S Safety Input Module power adapter

SKU CH-9ER0-HYG85

Allen-Bradley POINT Guard I/O safety module with eight current-sinking inputs, IEC 61131-2 Type 3 compliance and four test outputs rated up to 2.8 A at 40 °C

  • 8 safety inputs for distributed guarding
  • Type 3 sinking inputs meet IEC 61131-2
  • Test outputs deliver 2.8 A at 40 °C
  • circuit protection on every channel
  • Low 110 mA POINTBus current draw

POINT Guard I/O Safety Module

The Allen-Bradley 1734-IB8S is a POINT Guard I/O safety input module designed for industrial safety systems. It provides eight current sinking inputs rated to IEC 61131-2 Type 3. The module suits engineers building safety-related control architectures that require monitored discrete signals.

Module integration and test outputs

The unit mounts on a POINTBus backplane and draws up to 110 milliAmps from the bus. It supplies four test output sources (T0, T1M, T2, T3M) with an aggregate current of 2.8 Amps at 40 degrees Celsius and 0.55 Amps at 55 degrees Celsius. Short circuit protection is built into the outputs.

Upgrade from basic discrete input blocks

This module replaces standard non-safety discrete input blocks when safety integrity monitoring is required. The jump is worth it when the application demands pulse-tested inputs with a 144 millisecond pulse period and muting lamp control between 5 and 25 milliAmps. It is not for systems that only need basic on/off sensing without safety diagnostics.

Highlights

  • 8 safety inputs for distributed guarding
  • Type 3 sinking inputs meet IEC 61131-2
  • Test outputs deliver 2.8 A at 40 °C
  • circuit protection on every channel
  • Low 110 mA POINTBus current draw

Questions about this item

What is the maximum POINTBus current draw for the 1734-IB8S module?

The module draws a maximum of 110 milliAmps from the POINTBus backplane during operation.

How much heat must the cabinet dissipate when the test outputs run at full load in a 55 °C ambient?

At 55 °C the aggregate test output current is limited to 0.55 Amps, reducing the thermal load compared to the 2.8 Amp rating at 40 °C.

Which POINT Guard I/O base and safety controller are required to operate this module?

The 1734-IB8S mounts on a 1734 series POINT I/O terminal base and communicates with a GuardLogix or SmartGuard safety controller over the POINTBus.
