Product Description:

This controller can be used to control external relay/contactor, solid state relay (SSR), or control a small AC load directly. Please check the details for “model selections” below, and choose the desired Controller Output Option accordingly. 

PID Temperature Controller with 30 Steps Ramp/Soak

This is a brand new, dual display, 1/16 DIN (48 x 48 mm) programmable PID temperature/process controller. This controller is for applications where it is desirable to have adjusted set point automatically over time. Up to 30 steps can be programmed to A) ramp the temperature up and down at controlled rate, B) maintain the temperature for a specific period time, C) turn on/off the relays (alarm relay) after process reach a specific step, D) jump (for loops), run, hold or stop after process reaches a specific step. 

This controller has all the features of the standard PID controller (except the manual control mode). The dual alarm relay can be activated either by the temperature set point or by program steps. And can be used to interlock other equipments in the process.

12~24V AC/DC power supply version is also offered. Please check here

If you don't need the ramp/soak action, please see the other PID controllers without ramp/soak option.

  • Manual, technical support and 90-days warranty

Model Selection

We offer three models in this series: SYL-2342P, SYL-2352P, and SYL-2372P. Please read the description below to choose the correct model for your application. 

SYL-2342P (relay/contactor output)

This model has built-in relay can handle 10 A of current at 120VAC. That means 1200 watts of load can be connected directly to the controller without the need of an external relay or SSR. That is a very convenient for applications in which only a small heater is used. It can also be used to drive external relays or contactors.  It supports 17 different types of input devices that can be set by the user from keypad.

SYL-2352P (SSR output)

This model has 12 VDC output for controlling external solid state relays (SSR).

SYL-2372P (built-in SSR output)

Originally designed for the Traeger control. This unit has a built-in zero-crossing solid state relay (SSR) that can handle 2 Amp of load. The zero-crossing switching feature will avoid the noise caused by inductive load. It makes the controller more stable than the controller with relay contact output (SYL-2342) when switching inductive loads such as a contractors, solenoid valves, or small motors. Please note that this controller CAN NOT drive our DC triggered AC SSR. It CAN NOT handle more than 300W loads (at 110VAC) either.
