Wow, what a package! - Wired as intended, this gives tremendous temperature control flexibility. It comes in a neat little box with two clever nylon panel clamps. I'm still exploring and learning with this device, and I have to say that if you're not a control engineer, the specs/instructions are a little confusing --- and I already have some electrical/electronic experience. One thing I've noted in a number of discussions that bears mentioning --- and a solution: there is no "MANUAL ON" feature, which seems to be a hold-back for some folks, and may push them to a pricier unit. [edited, more to come on project] A solution I've used is relatively simple and costs just a few bucks: put in a low-voltage DC supply, and wire in 3PDT/Center-Off mini-toggle switches so that one throw provides DC voltage to a SSR, the other throw connects the TA4's terminals to the SSR, and center is off. I also threw in three bi-color LED's (off=off; red=auto; green=manual on). And three piezo buzzers --- each with its own mini-rocker switch to enable/disable. I added another mini-rocker as a master on/off, an RJ45 Keystone jack (to remote out the TA4 signals), an AC receptacle, and another SPDT rocker to select internal/external AC receptacle. Two identical project boxes, one with the TA4, an SSR (with cut-down heat sink), and all of the switches, etc. above; and another with two SSRs/sinks, an RJ45, a split AC receptacle (each relay operates one side), and a master kill toggle with a Tineon "live" light. Whew. The control box is 7.44" X 4.44" X 2.62". Next time I'll grind the parts up and pour them in. Anyway, if you go this way, you can get three separate control channels with three SSRs: OUT1(terms. 3/4); AL1 (terms. 4/5); and another on AL2 (terms. 11/12). The warning buzzers (if armed with the rocker switches) are entirely independent of whether the TA4 terminal signals are sent to the SSRs. A channel could be turned off, but its buzzer can still be live. The Manual On position overrides, and the SSR is lit regardless of TA4 action; The Manual Off position kills the SSR, regardless of TA4 signal. The RJ45 jacks allow me to use Cat 6/5e cable to put the main relays anywhere I want, and use the local receptacle if I want the thing to go portable. So I can check the storage freezer and the BBQ and the oven, and have the thing yell at me at three separate stages. My wife wants to know when I start taking up knitting ... This unit is ideal for crazy people who like to take simple projects and keep throwing parts and features in ... I will have a few photographs in a couple of days, and a partial parts list. The decal thing didn't work for me, but the layout is intuitive enough. (I asked my wife, and she could figure it out --- and she only "speaks" on/off. ;)) All of this, and I'm not even brewing. This runs three separate small fans in the bedroom --- and I get my "dual climate control" without freezing my wife. (I keep thinking of Kilmer's line in "red Planet:" "So, this is that time they told you about in high school, where algebra could save your life.") ## Features - Versatile Dual Display: Enjoy the convenience of a dual display that showcases both Fahrenheit (°F) and Celsius (°C) readings, allowing for easy monitoring of temperature across a wide range (-1999 to 9999, depending on the thermocouple used). - Wide Compatibility & Power Options: This programmable temperature controller supports various thermocouple sensors (K, J, E, S, T, B, R) and can be powered by an extensive voltage range of 80-265V AC/DC or 12-30V AC/DC, making it suitable for diverse applications in both industrial and home settings. - Output Capabilities: The controller features both mechanical relay (3A) and SSR outputs, providing flexibility in controlling high-current applications. - The one-key operation and auto-tuning PID/Fuzzy PID control ensure ease of use, while its reliable performance meets the demands of industries such as food & beverage, metallurgy, and more. - Compact & User-Friendly Design: Designed in a compact DIN 1/16 size (48mm x 48mm x 80mm), this temperature controller is easy to integrate into your existing systems. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005NGL4KG | | Best Sellers Rank | #142,518 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #185 in Temperature Controllers | | Brand | AGPTEK | | Brand Name | AGPTEK | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 208 Reviews | | Display Type | digital | | Item Dimensions L x W x H | 1.89"L x 1.89"W x 3.15"H | | Item Weight | 0.01 Ounces | | Manufacturer | AGPtek | | Material | Plastic | | Material Type | Plastic | | Model | PC4 | | Operating Temperature | 1200 Degrees Celsius | | Part Number | PC4 | | Product Dimensions | 1.89"L x 1.89"W x 3.15"H | | UPC | 847977056643 848454037698 | | Unit Count | 1.0 Count | | Voltage | 110 Volts | ## Product Details - **Brand:** AGPTEK - **Color:** Black - **Material:** Plastic - **Product Dimensions:** 1.89"L x 1.89"W x 3.15"H - **Voltage:** 110 Volts ## Images ![F/C PID Temperature Controller, AGPtEK Dual Display Digital Programmable Temperature Control TA4-SSR Solid State Relay with 2 Alarms - Image 1](https://m.media-amazon.com/images/I/41uY6X1eqeL.jpg) ![F/C PID Temperature Controller, AGPtEK Dual Display Digital Programmable Temperature Control TA4-SSR Solid State Relay with 2 Alarms - Image 2](https://m.media-amazon.com/images/I/41dVvwyd2sL.jpg) ![F/C PID Temperature Controller, AGPtEK Dual Display Digital Programmable Temperature Control TA4-SSR Solid State Relay with 2 Alarms - Image 3](https://m.media-amazon.com/images/I/51GEOgv9cKL.jpg) ![F/C PID Temperature Controller, AGPtEK Dual Display Digital Programmable Temperature Control TA4-SSR Solid State Relay with 2 Alarms - Image 4](https://m.media-amazon.com/images/I/51F2qu4xm0L.jpg) ![F/C PID Temperature Controller, AGPtEK Dual Display Digital Programmable Temperature Control TA4-SSR Solid State Relay with 2 Alarms - Image 5](https://m.media-amazon.com/images/I/512Dk1j9vsL.jpg) ## Questions & Answers **Q: what voltage is the SSR output?** A: Mine read 12VDC **Q: Title says "2 alarms". Details indicate one alarm. Which is correct?** A: This is the TA4-SSR. It has two SSR outputs and 1 alarm output. If you don't use the Second SSR output, it can be used as an alarms port also. The TA4-SNR has 1 SSR output and 1 Alarm output only. You want to make sure the listing says TA4-SSR or TA4-SNR somewhere so you know its what you want because they do make a TA4-RNR which has a relay output and wont run and SSR. **Q: Do the alarms have a hysteresis control on this PID?** A: This product have auto-tuning PID/ Fuzzy PID control. **Q: Is a ssr model different than a rnr model? using to control a bench top oven with solid state relay.** A: Hello Customer: Thank you for your inquiry. Yes the TA4-SSR is different from TA4-RNR. And you could use this product to control a bench top oven with solid state relay. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality item *by J***N on February 23, 2026* Works great, bright display and easy to set up and use ### ⭐⭐⭐⭐⭐ $23?
