Pricing Update: MSRP is expected to increase by Oct 30, 2026. Order soon to secure current pricing.
New product release (2/27/2026)! A WiFi-enabled PID controller with 4-20mA linear output.
The AW-SYL-2332 is a WiFi-capable 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). This unit not only does everything a non-WiFi version SYL-2332 does, but also has 2.4 GHz Wi-Fi connectivity, which allows a user to access the controller remotely through the AuberWifi phone app anywhere that has an internet connection.
A user can also convert the output to 1 - 5 VDC with a 250 ohm resistor. It can be used in controlling actuators, valves, dampers, or fans that require a linear input signal.
Please note: The main output in this model (AW-SYL-2332) is a linear 4 - 20 mA signal. It cannot directly drive an SSR or a mechanical relay.
Wi-Fi Connectivity Features:
- The AuberWifi app is available for both iOS and Android systems.
- Monitor the current sensor reading, view the data plot, and export historical data.
- Monitor the status of the main output and the alarm relays.
- Access and change all parameters from the app.
- Receive alarm notifications pushed to your phone.
- Easy pairing process. Compatible with most modern routers with 2.4 GHz WiFi bands.
- Manage multiple AuberWifi (AW) series devices in one app.
- Capable of receiving updates over-the-air (OTA).

Special Notes about AW-SYL-2332 with the AuberWifi app
- The current AuberWifi app doesn't support a display resolution of 0.1 degrees.
- It offers limited support for linear input sensor types such as DC voltage input and DC current input signals. The app fully supports all compatible temperature sensor types with 1°C or 1°F display resolution.
