Honeywell 203541 Connector

The Honeywell 203541 is a specialized 5-wire electrical connector engineered for seamless integration with the 7800 SERIES Relay Modules and S7800A Keyboard Display Modules. This critical terminal interface facilitates data communication, remote reset capabilities, and 13 Vdc power distribution within a daisy chain configuration. Built to withstand demanding industrial environments, the 203541 supports wire sizes from 14 to 22 AWG and remains operational in temperatures ranging from -40?F to +257?F. Whether you are performing a remote display mounting or configuring a ControlBus? module, this connector ensures a secure, low-impedance link for microprocessor-based burner control systems. The Honeywell 203541/U is a direct, identical replacement for the 203541, maintaining full compatibility with the S7800A1001 and other common KDM models. Technicians can rely on this 5-pin plug-in accessory to mitigate communication errors and signal loss in complex flame safeguard architectures.

• Universal Compatibility: Fully compatible with all 7800 SERIES relay modules and S7800A Keyboard Display Modules.
• Enhanced Communication: Provides reliable data highway termination for remote reset and system diagnostics.
• Rugged Design: Specifically rated for 5A and 300V, ensuring durability in high-vibration burner environments.
• Flexible Installation: Accommodates standard HVAC wiring sizes (14?22 AWG) for local or remote cabinet mounting.
• Direct Replacement: Seamlessly replaces legacy or damaged 203541/U connectors without requiring panel modifications.

Does the 203541 require a terminating resistor?
Yes, when the daisy chain leadwire run exceeds 100 feet, a 120-ohm resistor should be terminated across terminals 1 and 2 of the 5-wire connector to prevent signal reflection.

Can I use the 203541 for remote reset functionality?
Absolutely. This connector provides the necessary electrical landing points to link a remote reset pushbutton to the 7800 SERIES relay module up to 1,000 feet away.

Is the 203541 interchangeable with the 203541/U?
Yes, the 203541 and 203541/U are functionally and physically identical in terms of pinout and industrial specifications.
