Honeywell 10101/1/1 16-Channel Digital Input Module

Description

The Honeywell 10101/1/1 is a fail-safe digital input module designed to handle sixteen 24 Vdc digital input channels. The module features a 'fail-to-safe' design, ensuring that any component failure results in a de-energized input signal to the processor, thus maintaining safe conditions in a normally energized system. The remaining logic circuitry on the module is thoroughly covered by the system's self-test functions. The supply circuitry is divided into two galvanically isolated groups of eight inputs each, allowing for independent power supply groups and supporting segregation in a process unit or subunit structure.

  • Pins for 0 Vdc Supply (Group 2): d32, z32

Connection Examples:

1. Non-Redundant I/O Configuration:
   • Connect 24 Vdc (internal) power supply to pins z8, z18, z22, and z32.
   • Connect input channels as per schematic.
2. Redundant I/O Configuration:
   • Ensure both input groups are connected to the 24 Vdc (internal) power supply to prevent fault detection during self-test.
