Modine 5H0716750000 Relay Sequencer

The Modine 5H0716750000 Relay Sequencer is a critical OEM component designed for precise fan timer control across a wide range of industrial and commercial unit heaters. This fan timer relay sequencer acts as a direct replacement for legacy part numbers 5H71675 and ZC24A34-3-0145, ensuring seamless integration into existing control circuits without the need for field modifications. Constructed with a copper material base and silver contacts, this device provides superior conductivity and resists pitting during high-cycle automatic operation.

Engineered for high-duty cycles, the Modine 5H0716750000 utilizes a normally open contact type and screw connectors for secure terminations. The DIN rail mount design allows for rapid installation in standard control panels, maintaining a compact footprint of 3.4 x 3.2 x 1.8 inches. It is specifically compatible with Modine BDP, BV, PDP, and PV series unit heaters, facilitating the essential time delay relay function that prevents cold air discharge and protects the heat exchanger from thermal stress.

Key Benefits:

• Direct OEM Compatibility: Engineered as the official replacement for part numbers 5H71675 and ZC24A34-3-0145 to maintain factory performance standards.
• Enhanced Conductive Life: Features high-grade silver contact material to ensure reliable switching and long-term durability in heavy-duty HVAC environments.
• Standardized Installation: Includes a DIN rail mounting base and universal screw connectors for easy integration into unit heater control cabinets.
• Optimized Airflow Sequencing: Provides the necessary fan timer relay sequencing to manage fan startup and shutdown delays effectively.

Common Questions:

What are the primary symptoms of a failing fan timer relay?
Technicians typically observe the burner igniting while the fan fails to start, leading to the high-limit switch tripping and the system shutting down shortly after ignition.

Which Modine models utilize this specific sequencer?
This HVAC sequencer is verified for use in a broad range of Modine equipment, including many BDP, BV, PDP, and PV series units from 30,000 to 400,000 BTU capacities.

Does this unit support both heating and cooling sequencing?
Yes, it is designed for automatic operation modes in both heating and cooling unit heater applications where fan delay sequencing is required.
