THERMOCOUPLE
SIGNAL CONDITIONER
/ TRANSMITTERS
DIN Rail Mount
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.
