Mitsubishi A68RD4 Temperature Input Module
Function and application
The Mitsubishi A68RD4 is a temperature-input module identified in the manufacturer technical bulletin for four-wire resistance-temperature-detector connections.
The bulletin distinguishes the four-wire A68RD4 from the three-wire A68RD3 and identifies the specified Pt100 / JPt100 sensor arrangements. The measurement excitation is listed at 4.2–4.7 mA.
Technical specifications
| Parameter | Specification |
|---|---|
| Model | A68RD4 |
| Measurement | Resistance temperature detector |
| Connection arrangement | Four-wire |
| Sensor types in reviewed bulletin | Pt100 / JPt100, as specified |
| Measurement excitation | 4.2–4.7 mA |
Selection and installation
Confirm the exact RTD characteristic, wire arrangement and temperature configuration against the module instructions. A three-wire module or another RTD characteristic is a separate selection.
Record the installed sensors, controller, base and terminal wiring. The complete module manual should govern wiring and commissioning; a sensor name alone does not establish the complete measurement setup.
Quotation enquiries
Send Seven Star LLC the A68RD4 reference, quantity, controller and base-unit codes, and photographs of the existing label and connections. Identify any required terminal block, cable or accessory separately.
For an installed-system replacement, include the current station configuration and application requirements. Matching a module outline or channel count alone does not establish electrical, software or mechanical compatibility.

Mitsubishi NSX-2100 parts
The NSX-2100 was built with a horizontal or a vertical furnace, and one furnace can serve several detectors. The dryer set removes water from the combustion gas before it reaches the detector. Like the connection kits, it is a consumable, and its part code changes with the analyzer variant.Ordering NSX-2100 consumables: what we need
Send the part code, for example TN6RPC, together with the exact analyzer model shown on the nameplate (the letters after NSX-2100 indicate furnace type and detectors), the serial number and the detectors fitted. Some original part codes have been replaced by newer ones, so we check each code against the manufacturer's current parts list before quoting.Browse Mitsubishi products by category: Gas Analyzer Accessories.
