Overview
The Honeywell TC-MUX021 Serial Interface Module provides dependable and high-performance communication between industrial controllers and field devices. Designed with a double-slot width, it offers two independent communication ports that engineers can configure for either EIA RS-232D or EIA RS-422/485D interfaces. This flexibility allows users to integrate the module into a variety of control architectures, including SCADA systems and distributed automation networks.
The TC-MUX021 ensures reliable data transmission even in harsh industrial environments. Its rugged design resists vibration, shock, and electrical noise while maintaining stable serial communication. Engineers often use this module with Honeywell MU-TSIM12 (Modbus) and MU-TSIA12 (Allen-Bradley DF1) FTAs for robust and efficient system integration.
