New product release (9/24/2025)! A WiFi-enabled version (AW-SYL-2332) is also available.
The SYL-2332 is a 1/16 DIN size (1.89" x 1.89" or 48 x 48 mm) PID temperature/process controller with a linear output in 4-20 mA (at 12V). A user can also convert the output to 1-5VDC with a 250 ohm resistor. It can be used in controlling actuators, valves, dampers, or fans that require a linear input signal.
This controller shares the same hardware platform and features as the SYL-2352, which is one of our most popular PID controllers.
Please note: this controller's main output is a linear output (4-20mA). It cannot drive a SSR nor a mechanical relay directly.
Features:
- PID control algorithm with a fuzzy logic enhancement for outstanding control capability.
- 0.2% sensor reading accuracy over the entire input range.
- Displays temperature readings in either Fahrenheit or Celsius.
- Can display output level for easy troubleshooting.
- Supports both heating and cooling modes.
- Supports manual control mode and bumpless transfer between auto and manual control.
- Two built-in alarm relays with 10+ activation and assignment conditions.
- Support parameter-lock.
- High brightness, large LED display - easily read from a distance
- Manual and US technical support
- 6-month limited warranty. See details here.

Notes:
1. In SYL-2332, the parameter "OP-A" must be set to "1" to ensure the linear output works correctly.
2. Optional 10 pcs spade connectors (for 22 ~ 16 AWG wire) are available. Colors are randomly picked, either red or blue.
