Pros & Cons
Pros
- ✓ 40DA solid state relay included, so no separate SSR purchase
- ✓ Accepts 100-240V AC input for use on most mains supplies
- ✓ Dual display shows live temperature and setpoint together
- ✓ Takes 2-wire or 3-wire sensors, including K-type thermocouples
- ✓ Alarm relay rated AC250V 3A, NO or NC, can drive a buzzer
Cons
- ✗ Requires mains-voltage wiring, so not a plug-and-play unit
- ✗ Only one SSR control output, so one heating zone per controller
- ✗ Alarm relay 3A rating is for resistive loads only
- ✗ Probe not listed in kit contents, so confirm before ordering
Manufacturer description
The Inkbird PID Temperature Controller Kit gives you precise, closed-loop temperature control for DIY projects that need a steady setpoint, such as heaters, kilns, smokers, or brewing rigs. It runs on 100 to 240V AC mains power, so the same kit works in most regions without a separate supply. The kit includes a 40DA solid state relay. The controller drives it through a dedicated SSR output, which lets you switch your heating load without the wear of a mechanical contactor. The controller needs an SSR or relay to work, and this one comes in the box. A separate alarm relay is rated AC250V, 3A…
SpecPicks Verdict
SpecPicks scored Inkbird PID Temperature Controller Kit using a rating × review-volume × price-fit model applied to published specs and reviews across the controllers & gamepads category. Inkbird's controllers & gamepads lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for controllers & gamepads of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Does the Inkbird PID controller kit come with a solid state relay?
Yes. A 40DA SSR is included. The controller needs an SSR or relay to switch your load, and it drives one through its dedicated SSR output.
What temperature sensors work with this controller?
It supports both 2-wire and 3-wire sensors, including K-type thermocouples. Check the product listing to confirm whether a probe is included in your kit.
Can I use it on 220V or 240V power?
Yes. The controller accepts 100 to 240V AC input, which covers both 120V North American and 220-240V supplies.
What can I connect to the alarm output?
The alarm relay is rated AC250V, 3A for resistive loads and can be set to NO or NC. You can wire a buzzer or another low-current indicator to it.
Can the display show Fahrenheit instead of Celsius?
Yes. You can set the readout to Celsius or Fahrenheit. Both the real-time temperature and the setpoint show at the same time in two display windows.
Key Features
- Alarm Output: With 1 alarm relay output, AC250 V, 3 A (Resistive load), ON or NC, you can wire a buzzer
- Supports 3-Wire Sensor: a 3-wire sensor or 2-wire sensor, like the K type thermocouple and Cu500, is supported by this PID temperature controller
- SSR Output: With 1 relay output for external SSR, an SSR or relay is a must for this temperature controller; A 40DA SSR is included
- Digital Display Celsius or Fahrenheit: It’s a digital PID controller but also supports Centigrade or Fahrenheit reading
- 2 Temp Displaying Windows: The real-time temperature and the setpoint are shown at the same time
