Honeywell TK-MUX021 51404391-375 Experion LS Serial Interface Module
The Honeywell TK-MUX021 (part number 51404391-375) is a dual-channel serial interface module designed for Honeywell Experion LS control platforms. Occupying a double-slot chassis width, it bridges data exchange between Honeywell controllers and external field hardware such as PLCs, drives, and instrumentation. The TK-MUX021 features factory conformal coating, providing physical protection against moisture and corrosive airborne contaminants.
Serial Communication and FTA Integration
The module provides 2 communication channels, each dedicated to a Field Termination Assembly (FTA). Depending on the connected FTA, physical signal levels are selectable between EIA RS-232D and EIA RS-422/485D with communication speeds up to 19.2 kbps per channel. It supports industrial protocol integration via specialized FTAs, including the MU-TSIM12 for Modbus and the MU-TSIA12 for Allen-Bradley DF1 networks.
Hardware Interface and Power Requirements
A single controller supports up to 3 serial interface modules, drawing power via a TC-KSM003 power adapter cable connected to either a 24 VDC supply adapter (TC-SMPD01) or an 85–265 VAC supply adapter (TC-SMPC01). Designed for demanding mechanical environments, the unit exhibits a maximum power dissipation of 10 W, withstands operating shock up to 30 g peak (11 ms duration), and meets 5 g vibration resistance from 10 to 50 Hz.

Frequently Asked Questions
Q: What is the difference between the Honeywell TK-MUX021 and TC-MUX021 modules?
A: The TK-MUX021 is the conformally coated version of the standard TC-MUX021 module, designed to protect electronics from harsh industrial atmospheres.
Q: Which protocols and physical interfaces are supported by the TK-MUX021?
A: It supports RS-232D and RS-422/485D interfaces running up to 19.2 kbps per port, interfacing with Modbus (via MU-TSIM12 FTA) or Allen-Bradley DF1 (via MU-TSIA12 FTA).
Q: How is external power supplied to the TK-MUX021 serial interface module?
A: Power connects via a TC-KSM003 adapter cable using either a 24 VDC power supply (TC-SMPD01) or an 85–265 VAC power supply (TC-SMPC01).
