Overview
The Honeywell 8U-TDODA1 is a non-redundant, uncoated Digital Output Termination Assembly (IOTA) designed for the Experion C300 controller within the Series 8 platform. This module provides 32 source-type 24V DC outputs, facilitating passive field termination and ensuring reliable signal processing in industrial automation systems.
The Digital Output Bussed 24VDC has provisions for both internal and external field power excitation. As a bussed output device, all of the outputs share a common return (ground). All outputs get their power from the same source, which can be either the system power supply or an externally connected 24V power supply. When selection is from an external source, outputs can be galvanically isolated from the Series 8 power system. A wiring option on the IOTA determines if outputs are referenced to the Series 8 system power or an external field power source.
