Johnson Controls A350PS-7 Proportional Temperature Control with Sensor 60-105°F

The Johnson Controls A350PS-7 is an electronic proportional plus integral (PI) temperature control from the System 350 series, designed for precise temperature management in HVAC and building automation applications. This control features a setpoint range of 60 to 105°F (16 to 41°C), making it ideal for comfort heating and cooling applications.

Key Features:

• Proportional plus integral control for faster response and stable temperature management
• Dual analog outputs: 0 to 10 VDC and 0 to 20 mA for versatile equipment control
• Includes A99BC-25C PTC silicon temperature sensor with 9-3/4 inch lead
• Adjustable throttling range (proportional band) from 2 to 30°F
• Field-selectable reverse or direct-acting operation modes
• Ten-segment LED bar graph displays percentage of output signal
• Minimum output adjustable from 0 to 60 percent
• 24 VAC/VDC power supply operation
• DIN rail or surface mounting capability
• NEMA 1 enclosure for indoor applications

The A350PS-7 can be used as a standalone temperature controller or integrated with optional plug-in accessory modules including the S350 Staging Module, D350 Digital Display Module, and Y350R Power Module for expanded functionality. The proportional plus integral control algorithm maintains setpoint regardless of load shifts, providing consistent temperature control with minimal overshoot. Terminal block accepts 12 to 26 AWG wire for easy installation.
