Features:
- Bridge Between the Control System Backplane and Field Analog Output Devices
- Integrates 16-Channel AO Signal Distribution with Protective Circuit Coating Technology
- Functions Cooperatively with Honeywell C300 and Experion PKS Control Environments
The Honeywell 8C-TAOX51 Analog Output IOTA module operates as the coated termination assembly in a Series 8 I/O rack, providing reliable analog output signal routing to all field devices within the control loop. It continuously transmits 4-20 mA or other standard analog signals from the controller through the backplane to 16 individual field terminations, ensuring precise control of final control elements such as control valves, variable frequency drives, and actuator positioning systems. Enhanced environmental protection is standard with the 8C-TAOX51, as its coated circuit design resists moisture ingress and corrosive contamination that would otherwise degrade unprotected termination assemblies in harsh process environments. The 8C-TAOX51 has incorporated significant improvements in signal integrity and durability over previous IOTA designs in addition to providing robust 16-channel analog output capability within the Honeywell control architecture.
The 8C-TAOX51 provides essential signal interface functions common to the entire analog output path, and is a critical component of the control loop, directly affecting the proper, accurate operation of the overall process control system. One 8C-TAOX51 module is required per 16-channel analog output segment, with multiple units deployable depending on the required I/O density. The 8C-TAOX51 occupies a standard slot position in the IOTA rack and interfaces directly with the associated Series 8 analog output module.
For expanded analog output applications, the Honeywell system supports multiple 8C-TAOX51 modules installed across available slots. In addition to standard single-module operation, the modular configuration also enables scalable channel expansion. The 8C-TAOX51 channel architecture executes signal distribution using the internal circuitry specified in the IOTA design specifications. Using this method, the analog output system continually maintains signal fidelity across all 16 channels. If the system detects that a particular channel requires recalibration or the module identifies a signal drift condition, operators can address individual channels while the remaining 15 outputs on the 8C-TAOX51 continue normal operation, with status events logged in the System Event List.
The 8C-TAOX51 Honeywell Analog Output IOTA module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
