Reznor 171134 Modutrol IV Control Interface Module

The Reznor 171134 is a control interface module designed for use with Honeywell Series 90 Modutrol IV motors in Reznor MAPS III and IV HVAC systems. This interface module (Honeywell Q7230A1005) converts Series 90 Modutrol IV motors for compatibility with Series 70 electronic controls, providing flexible control options for damper actuators and valve control applications.

Key Features:

• Adjustable zero and span control with voltage or current options (2-10 VDC or 4-20 mA)
• Mounts directly inside the wiring junction box of any Series 90 Modutrol IV motor
• Protected from weather by motor's NEMA 3 rated wiring box
• Solid-state circuitry with surface mount components for reliability
• Mates to motor's quick-connect terminals and provides screw terminals for control wiring
• Includes reversing switch to allow replacement of electrically normally open or electrically normally closed motors
• Operating temperature range: -40°F to 150°F
• Power consumption: 2 VA at 50/60 Hz

This interface module is commonly used in Reznor commercial HVAC equipment for precise control of dampers and valves in heating, cooling, and ventilation applications. The adjustable span and zero settings allow customization for specific system requirements.
