Johnson Controls A350P Series Electronic Proportional Plus Integral Temperature Control

Electronic Proportional Plus Integral Temperature Control
A350P Series

The A350P Electronic Proportional Plus Integral Temperature Control Series has two proportional outputs of 0 to 10 VDC and 0 to 20 mA. This control is used in conjunction with the A99B Series (PTC silicon) Temperature Sensors. Two controls cover a temperature range from -30 to 250°F with an adjustable throttling range (proportional band) of 2 to 30F°. Proportional plus integral (PI) control is an option to hold setpoint regardless of load shifts on the system. A temperature sensor (A99BC-25C) is included with each A350P control. The S350 Staging Module, D350 Display Module, and Y350R Power Module can be used with the A350P.

• field-selectable proportional only or proportional plus integral control
• plug-together connectors and 35 mm DIN rail mounting eliminate wiring between models and reduce installation costs
• ten segment LED displays percent of output signal
• field-selectable reverse or direct-acting mode
• minimum output adjustable from 0 to 60%
• two models cover a wide setpoint range of -30 to 250°F (-35 to 121°C)
