It provides 2 channels of configurable inputs, and supports multiple voltage, RTD, thermocouple inputs with auto reference junction compensation. If parallel connected to an external precise resistance, it accepts current signal input. Each channel has its own digital filtering and can adjust its filtering degree.
  • It generates two isolated current outputs, 4 to 20 or 0 to 20 mA. The range of retransmission output can be freely defined.
  • The model is DIN rail mounted. Its width is only 22.5 mm. The instrument can be easily configured by connecting to our E8 handset display.
  • Universal power supply of 100 to 240 Vac or 24 Vdc.

Rated 5 out of 5 by from Great value & space saver for cost I have a hobby greenhouse for peppers, tomatoes, peas, beans, carrots & cucumbers over the past 5 years. As a retired Instrument Technician (who enjoys the trade) I've mostly automated the greenhouse with used surplus instrumentation. After having some drifting issues with previous temperature xmtrs, I tried my luck with a pair of these TXDIN70-24 xmtrs & a Display unit 3 years ago. I was very pleased with the ease of setup, dual inputs & DC power version (I didn't want any AC influence on my T/Cs). I measure outside & various inside temps which are processed by these xmtrs before being passed on to other controls. A couple of years back I made a pair of removable mini greenhouses that I call 'Table-Frames'. They are tied together with 3" PVC dryer hose. Each has a removable wood framed glass roof & a 150W heater (earlier purchased from Omega that is pulse duration controlled via a PLC. A small fan in the left T-F recirculates the air. I use these to keep some seedlings just above freezing as the GH does go below freezing over the winter. These are removed late Spring to make room for other plant pots. I've since purchased another 2 TXDIN70-24s for each T-F as well as the deep Carrot bin soil temps.

Rated 4 out of 5 by from Needs to Be Packaged w/ Programmer Works well now, after a second purchase and additional $19 in shipping for programmer. A little frustrating that the signal conditioner comes without the programmer, and you have to order it separately. It seems like if you are familiar with the product, you should be able to special order it without the programmer, not the other way around where you are psyched for the modules price point, order it, get it on hand, and find you have to pay another $45+ dollars (including shipping) to simply use it.

Rated 5 out of 5 by from Great price and easy to program. I used this transmitter to replace 2 ABB single channel units on RTD's at a quarter of the price. Very easy to program once I played around with the controller a bit.

Rated 5 out of 5 by from Great Value Extremely versatile TC transmitter. Works for virtually any type of thermocouple. Uses 120 VAC power. Easy to program for any range of operation. Provides stable, noise free mA signal to process and data acquisition and recording systems.

Can this be programmed with a computer? You have no TXDIN70-Displays available to purchase.

Asked by: Comp
Thank you for the inquiry. Unfortunately the TXDIN70 cannot be programmed with PC connection. Lead time for the module is 3 weeks. Best regards, OMEGA

Hello. I'm trying to connect an Omega RTDM12 compact RTD probe to this transmitter. Can you please tell me which pins from the probe connect to which input terminals on the transmitter? Thanks.

Asked by: RobE
Hi RobE Thank you for the inquiry. On the RTDM12 series the 2 conductors adjacent to the key will go to 14,15 ( order does not matter). Then 1 of the 2 remaining conductors will connect to 16. Same sequence applies to Input 2. Best regards OMEGA

Hy Omega, What are the response times: Start up; Update; Response and Warm up? If I program it to a range of something, will store it in the memory? Will restore it when bootloading? eg if the power is switched off and on. Best regards,

Asked by: SGabor
Thank you for your inquiry. The sampling rate is 11~12 times per second. This device aves parameter changes whether the unit is on or off.
