Terminator Resistor 209541B Honeywell

Terminator Resistor 209541B Honeywell

Condition: New.

The Honeywell 209541B/B is a termination module designed for use in Free Topology Transceiver (FTT) and Linked Power Transceiver (LPT) networks, particularly within Honeywell’s Excel 10™ Building Management System (BMS). Proper network termination is essential for maintaining signal integrity and ensuring reliable communication across the E-Bus network. This module provides a straightforward solution for terminating various network topologies, thereby enhancing overall system performance.

Features
Versatile Topology Support: Compatible with T-tap, star, loop, mixed, and daisy-chain network configurations.
Termination Requirements:
Single module required for T-tap, star, loop, or mixed topologies.
Two modules required for daisy-chain topologies.
Flexible Installation: Can be installed at controller nodes, wall modules, or wiring junctions.
Simple Wiring: Features three lead wires (brown, yellow, and orange) for easy connection; only two are used depending on the termination type.
Polarity Insensitive: E-Bus connections do not require polarity matching, simplifying installation.
Compact Design: Small form factor allows for installation in various locations without requiring additional space.

Applications
Building Automation Systems: Ensures reliable communication in Honeywell Excel 10™ BMS networks.
HVAC Control Systems: Maintains signal integrity in heating, ventilation, and air conditioning networks.
Industrial Automation: Supports robust data transmission in industrial control systems utilizing FTT/LPT networks.
Energy Management Systems: Facilitates accurate data exchange in systems monitoring and controlling energy usage.
