1. Product Overview – Honeywell 8C-TCNTA1-C
The 8C-TCNTA1-C is an I/O Termination Assembly (IOTA) module from the Series 8 platform designed for use with Honeywell’s C300 distributed control system (DCS). It serves as a connection interface between field devices (such as sensors and actuators) and the I/O modules (IOMs) of the control system.
The “C” suffix indicates the module is coated with a conformal protective layer, making it suitable for harsh industrial environments prone to moisture, dust, and corrosive gases. This coating improves long-term reliability and robustness in critical control applications.
Though passive in function (i.e., it does not perform processing), the 8C-TCNTA1-C plays a key role in organizing, isolating, and protecting I/O wiring between the field and the control system.
