Supported Applications
The Omega TXDIN70 Series is a dual-channel DIN rail temperature transmitter and signal isolator designed for industrial process instrumentation. The series accepts ungrounded thermocouple inputs, RTD sensors, linear voltage signals, or user-defined linear input units (-9990 to 30,000). It provides retransmission of these measurements into configurable current outputs suitable for data acquisition and control systems.
Operating Conditions & Performance
The TXDIN70 Series operates within an ambient temperature range of -10 to 60°C with humidity up to ≤90% RH. Retransmission accuracy is specified as 0.3% full scale ±1 digit, including input and output error. Temperature drift is rated at ≤0.015%FS/°C (including the temperature drift of input and output). The device features digital filtering with an adjustable degree for each channel.
Input ranges vary by sensor type:
- Thermocouples: K (-50 to 1300°C), S/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, with measurement accuracy only at 400 to 1800°C and less accurate from 60 to 400°C), N (-50 to 1300°C), WRe5-WRe26 (0 to 2300°C).
- RTDs: Pt100 (-200 to 900°C) and Cu50.
- Linear Voltage: 0 to 20 mV, 0 to 60 mV, 0 to 100 mV, 0 to 1 V, or 0.2 to 1 V.
The output specification allows signals to be freely defined in the range of 0 ~ 22 mA with a maximum output voltage ≥11V (commonly configured as 4 to 20 mA or 0 to 20 mA). Isolation withstands voltage between power, signal input and output terminals at ≥2300 Vdc. Electromagnetic compatibility meets ±4KV/5KHz according to IEC61000-4-4 (EFT) and 4KV according to IEC61000-4-5.
Configuration Options
The series is configured for DIN rail mounting with overall dimensions of 100 H x 22.5 W x 100 mm D (3.9 x 0.89 x 3.9") and a weight of 85 g (0.18 lb). Power options include universal AC or DC supply:
- TXDIN70: Powered by 100 to 240 Vac, -15%, +10% / 50 to 60 Hz.
- TXDIN70-24V: Powered by 24 Vdc.
Configuration is performed using an E8 handset display. An optional external plug-in display module (model TXDIN70-DISPLAY) connects to the transmitter for local monitoring. The device supports auto reference junction compensation and includes a CE approval mark. Power consumption is ≤3W.
Key Product Differences
The primary distinction within the series lies in power supply requirements: standard models accept 100~240VAC, while the -24V variant accepts 24 Vdc. Both variants share identical input capabilities and output specifications. The TXDIN70-DISPLAY is an accessory option rather than a standalone transmitter model; it provides visual feedback for the installed unit.

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.

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.

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.

Hello, Omega, I would like to ask whether TXDIN70 can be connected to the computer for data collection
Hi bao77,
Thank you for the inquiry. Unfortunately this device has no communication options for data collection.
Best regards

I am going to have this connected to an ABB ACS800 via loop power. How do i wire it up so that the output is transmitted correctly? At the moment i have loop power coming into the transmitter at terminals 1 & 2.
Hi ITT EMD,
Thank you for the inquiry. Unfortunately this unit will not work in a loop powered configuration. For assistance locating a loop powered transmitter please email TEMP@OMEGA.COM.
Best regards,

I'm measuring the temperature of electrically live components up to 700 VDC and VAC, and I'm look at using a few of these to isolate the signal so I can measure the TC's with a DAQ system. What is channel to channel isolation of this unit?
Hi Cwitry
Thank you for the inquiry. TXDIN70 inputs are not isolated from each other. Please forward your request to our data acquisition group at DAS@OMEGA.COM.

What is the standard temperature at which the specifications are defined? For example, the Temperature Drift is stated in %FS/Degree C. For me to provide an Uncertainty Calculation it is require to know the difference between operating and spec temp.
Hi Lonzo,
Please forward this question to TEMP@DWYEROMEGA.COM.

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

Can this be programmed with a computer? You have no TXDIN70-Displays available to purchase.
Thank you for the inquiry. Unfortunately the TXDIN70 cannot be programmed with PC connection. Lead time for the module is 3 weeks.
