Product Description
The Honeywell 8C-TAOXA1 (Part Number: 51307135-175) is a non-redundant Analog Output I/O Termination Assembly (IOTA) designed for Series 8 systems within the Honeywell Experion Process Knowledge System (PKS). This module serves as the connection interface between the analog output IOM (such as 8C-PAONA1 or 8C-PAOHA1) and the field wiring, supporting 4–20 mA signal transmissions for controlling final elements such as actuators and valve positioners. Its compact form factor and plug-and-play connectivity with IOMs ensure efficient installation, maintenance, and robust operation in industrial control systems.
