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.
• 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
