Product Overview: Honeywell 51309142‑175 (MC‑TSTX13)

The MC‑TSTX13 (51309142‑175) is a Smart Transmitter Interface (STI) module from Honeywell’s MC Series, designed as a high‑performance I/O component for the TDC 3000 / PKS DCS systems. It serves as the critical bridge between Honeywell’s UCN (Universal Control Network) controllers and field‑mounted smart transmitters, enabling reliable, high‑precision data acquisition and communication in process automation.

Description

Key Features

16‑Channel Analog Input (AI/STI): Supports 4–20 mA analog signals and digital protocols including HART, FOUNDATION Fieldbus, and Modbus RTU.

High Accuracy: Delivers ±0.05% of full scale precision, preserving field instrument accuracy without resolution loss.

Multi‑Drop Capability: Each channel supports up to 15 HART devices or 30 Honeywell DE transmitters, reducing wiring costs.

Channel‑to‑Channel Isolation: Provides electrical isolation to prevent signal interference and enhance system reliability.

Robust Environmental Performance: Operates reliably from –20°C to +70°C (storage: –40°C to +85°C) with conformal coating for harsh industrial environments.

Fast Response: < 100 ms response time for real‑time process monitoring and control.

Certifications: CE, UL, RoHS, and SIL‑compliant (IEC 61508) for safety‑critical applications.

Applications

Widely deployed in oil & gas, petrochemicals, power generation, metallurgy, and water treatment industries, this module integrates smart transmitters (pressure, temperature, flow, level) into Honeywell DCS for seamless process control, monitoring, and diagnostics.
