Note: SYL-2L42H is a low voltage version humidity PID controller, and it can only be powered by 24V AC/DC. For 110V/240V power supply option, please check here.
This high-precision, industrial grade relative humidity controller can be used for sausage drying, incubators, and greenhouse humidity control.
This controller has some useful features that many other humidity controllers on the market don't have.
The dual display allows the user to see both set humidity and actual humidity at the same time. This is a useful feature for applications in which humidity settings need to be changed frequently. If you forget the humidity setting, you don't have to push any buttons to find out.
The main control output can be set for either increasing or decreasing the humidity. The controller also has two programmable alarm relays that can be set as absolute alarms or deviation alarms to warn the user when the humidity is beyond a set point. The alarm output can also be used in conjunction with the main control output as a dual output controller. Users can use the main control output to drive a humidifier and the high limit alarm output to drive a dehumidifier. When the humidity is below the set point, the humidifier will be on. When the humidity is above the set point, the dehumidifier will be turned on.
A fast response, capacitive relative humidity sensor (HSR-2342H) is included. It has high accuracy, high reliability, consistency, and is temperature compensated.
In addition to the on/off control mode which meets the needs of most applications, the controller can also be set to PID control mode for higher precision control.
All settings can be locked with a passcode to prevent accidental changes by the operator.
Note 1: Typical lead time for this product: 1-2 business days.
Note 2: If you need a similar PID controller to drive Solid State Relay (SSR) instead, please contact us for details.
Note 3: This controller cannot read temperature sensor like RTD or thermocouple. For linear signal input, this controller can read 0-20mA (w/ 250 Ohms resistor, not included), 4-20mA (w/ 250 Ohms resistor, not included), 0-5V or 1-5V. It cannot read 0-1V or 0.2-1V.
