Main features and advantages:
A key strength of the HONEYWELL FC-TSHART-1620M is its advanced HART communication capabilities. The module supports both point-to-point and multi-drop HART configurations, allowing up to 15 devices to share a single loop in multi-drop mode—significantly reducing wiring costs in large facilities. It handles HART 7, the latest version of the protocol, ensuring compatibility with modern smart sensors while maintaining backward compatibility with older HART 5 devices. This versatility allows the HONEYWELL FC-TSHART-1620M to communicate with a wide range of instruments, including pressure transmitters, temperature sensors, level meters, and control valves, regardless of manufacturer. Hardware-wise, the module features a compact design with a robust metal housing that withstands industrial environments, including vibration up to 5g and operating temperatures from -40°C to 70°C. Its low power consumption (less than 15 W) makes it suitable for installation in crowded control cabinets where heat management is a concern.
Reliability and data integrity are central to the HONEYWELL FC-TSHART-1620M’s design. It incorporates advanced error-checking algorithms that ensure HART data is transmitted without corruption, even in noisy industrial environments with electromagnetic interference. The module’s auto-detection feature automatically identifies connected HART devices, simplifying commissioning and reducing setup time—engineers can view a complete list of connected instruments and their status within minutes of power-up. For diagnostics, the HONEYWELLFC-TSHART-1620M continuously monitors loop integrity, device health, and communication quality, alerting operators to issues such as sensor drift, wiring faults, or low battery levels in wireless HART adapters. Its redundant communication ports prevent single points of failure, ensuring uninterrupted data flow between field devices and the DCS. Like other Honeywell modules, the HONEYWELL FC-TSHART-1620M supports hot-swapping, allowing for maintenance or replacement without disrupting the 4-20 mA signal loops—critical for maintaining process continuity in 24/7 operations.

FC-TSHART-1620M
Application areas:
In industrial facilities where seamless communication between smart sensors and control systems is the backbone of efficient operations, a reliable HART interface module is essential. Consider a large chemical plant with 16 different pressure transmitters spread across reactor units, each requiring not just basic measurement data but also diagnostic information to prevent unplanned downtime. Or a water treatment facility where 20 flow meters need to be calibrated remotely to maintain accuracy without disrupting the purification process. These are the scenarios where the HONEYWELL FC-TSHART-1620M shines, serving as a critical bridge in industrial automation systems that rely on HART protocol devices. Used in industrial automation setups ranging from oil refineries to pharmaceutical manufacturing plants, the HONEYWELL FC-TSHART-1620M is engineered to unlock the full potential of smart sensors by enabling bidirectional communication—transmitting process data to the controller while allowing remote configuration and diagnostics of the devices themselves. It’s particularly valuable in applications where centralized management of multiple HART instruments is needed, such as in modular production lines or facilities undergoing digital transformation. The HONEYWELL FC-TSHART-1620M addresses the challenge of integrating legacy 4-20 mA devices with modern HART-enabled sensors, ensuring compatibility while maximizing the value of smart instrumentation investments.

Installation and maintenance:
Before installing the HONEYWELL FC-TSHART-1620M, ensure the mounting rail is properly grounded to minimize electrical noise, which can disrupt HART signal integrity—this is especially important in environments with nearby variable frequency drives or high-voltage equipment. Verify that the control cabinet has sufficient space to accommodate the module and connected wiring, with a minimum clearance of 50 mm on all sides to facilitate airflow. When wiring the HONEYWELL FC-TSHART-1620M to field devices, use shielded twisted-pair cables for HART loops, with the shield terminated at both the module and device ends to prevent interference. For multi-drop configurations, calculate the total loop resistance to ensure it falls within the 250–1100 ohm range required for reliable HART communication. Label each channel clearly with the connected device type and tag number to simplify troubleshooting and configuration.
For maintenance, schedule semi-annual checks of the HONEYWELL FC-TSHART-1620M’s communication performance using Honeywell’s HART Test Tool, which verifies data integrity and response times. Conduct monthly visual inspections to check for loose connections or corrosion on terminal blocks, which can degrade signal quality. Use the Experion PKS software to run HART network health reports quarterly, monitoring for devices with increasing communication errors or delayed responses—these may indicate wiring issues or failing instruments. The HONEYWELL FC-TSHART-1620M supports online firmware updates, allowing for performance enhancements without interrupting process loops. With proper care, the module is engineered to provide reliable service for 12+ years in typical industrial environments.
