Johnson Controls W351P Electronic Proportional Plus Integral Humidity Control

Electronic Proportional Plus Integral Humidity Control
W351P

The W351P Electronic Humidity Control series has proportional outputs of 0 to 10 VDC and 0 to 20 mA. Proportional plus integral (PI) control is an option to hold setpoint regardless of load shifts on a system. The control covers a range of 10 to 90% RH and has adjustments for setpoint, integration constant, throttling range, minimum output, and mode (humidification or dehumidification). This control is used in conjunction with the HE-67S3-0N0BT or HE-67S3-0N00P series of humidity transmitters. The S351 Stage Module, Y350R Power Module, and D351 Display Module can be used with the W351P.

• field selectable proportional only or proportional plus integral control
• surface or DIN rail mounting
• ten segment LED displays percent of output signal
• field selectable humidification or dehumidification mode
• minimum output adjustment
• 5-pin connectors eliminate wiring between modules
