DRX-TC Thermocouple Signal Conditioner/Transmitters

The INFINITY^® signal conditioners provide high accuracy isolated measurement of thermocouple sensors. For maximum flexibility, the units feature user configurable thermocouple types which are fully field scalable.

Two models are available, the DRN-TC which provides an analog output that is proportional to the input signal and the DRX-TC which uses a digital RS-485 communication link. Both models can accept 9 different thermocouple types. Thermocouples supported include J, K, T, E, R, S, B, N, and J DIN.

The output of DRN-TC can be user set for 0-10 V, 4-20 mA or 0-20 mA. Input scaling and configuration of other operating parameters is accomplished by connecting to a standard RS232 port of a personal computer and using the DRN-CONFIG, Windows-based setup software. Once configured the settings may be stored in non-volatile memory and the unit disconnected from the PC.

The DRX-TC is a digital signal conditioner which communicates over an RS-485 communication link. Up to 32 modules may be connected to a single RS-485 port stretching up to 4,000 ft. Through the use of RS-485 repeaters, additional modules may be used and further transmission distances are achievable.
