Description

The Honeywell 8C-TAOX51 (part number 51306983-175) is a conformal-coated, non-redundant 6-inch Input Output Termination Assembly (IOTA) designed for PlantCruise Series 8 process control systems. It combines field wiring termination and the Analog Output Input Output Module (IOM) into a single compact area, eliminating the need for a separate electronics chassis. Operating directly from a 24 VDC carrier power bus, the unit delivers non-incendive field power distribution across 16 channels without requiring external marshalling or inline fusing. The assembly features two-level detachable screw terminals, integrated signal conditioning, and on-board connection to the I/O Link for standard 4-20 mA and HART-capable analog output operations.

Features

  • Combines field terminations and I/O module mounting in a single unit, eliminating external chassis requirements.
  • Equipped with two-level detachable terminal blocks for simple field wiring installation and maintenance.
  • Supplies non-incendive field power directly through an integrated 24 VDC bus connection on the carrier.
  • Conformal coating protection (8C designator) against humidity, dust, chemicals, and temperature extremes.
  • Vertical mounting orientation and tilted physical layout engineered for cabinet space efficiency and heat management.
  • Short-circuit protected output circuits that eliminate inline fusing needs.

Applications

  • Field wiring termination and power distribution for 16-channel 4-20 mA analog output devices.
  • Interfacing actuators, positioners, and recording instruments in Honeywell PlantCruise by Experion architectures.
  • Class 1, Division 2 hazardous area deployments requiring non-incendive field power conditioning.
