Product Specs

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.
Input Type
Thermocouple: K, J, T, E, R, S, B, N WRe5-WRe26
RTD: Pt100, Cu50
Linear Voltage: 0 to 20 mV, 0 to 60 mV, 0 to 100 mV, 0 to 1V, 0.2 to 1V
Instrument Input Range K(-50 to 1300°C), S(-50 to 1700°C), R(-50 to 1700°C), T(-200 to 350°C), E(0 to 1000°C), J(0 to 1200°C), B(0 to 1800°C), N(-50 to 1300°C), WRe5%WRe26(0 to 2300°C), Pt100(-200 to 900°C)
Linear Input: -9990 to 30,000 units defined by user
Retransmission Accuracy: 0.3% FS ±1 digit (including input and output error)
Output Specification: Can be freely defined in the range of 0 to 22 mA with maximum output voltage ≥11V
Temperature Drift: ≥0.015%FS/°C (including the temperature drift of input and output)
Electromagnetic Compatibility (EMC): ±4 KV/5 KHz according to IEC61000-4-4 (EFT); 4 KV according to IEC61000-4-5
Isolation Withstanding Voltage: Voltage between power, signal input and output terminals ≥2300 Vdc;
Power Supply: 100 to 240 Vac, -15%, +10% /50 to 60 Hz; or 24VDC
Power Consumption: ≥3W
Operating Ambient: Temperature -10 to 60°C; humidity ≥90%RH
Note: B thermocouple obtains the above measurement accuracy only at the range of 400 to 1800°C. It's measurement from 60 to 400°C is less accurate.

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 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 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.

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.

hello, This unit TXDIN70 i'm using did not transmit analog output, even display shows correct temperature. Happens on both output. Please advise.

Asked by: adli
Hi Adli, Most likely problem is the output wiring. Please review terminal connections for outputs. Second possibility could be the output scaling selected. Please review settings. Manual gives an example output scaling for reference. For more assistance please call us in the temperature group. 800-359-1660 and ask for the temperature tech support group. Best regards OMEGA
