Multifunctional Signal Conditioner
Multifunctional Signal Conditioner
Product Description
The signal conditioner incorporates two bright easy to read LCD Displays which indicate Process Value (PV) and user selected parameter.
The RSC is a specially designed signal conditioner which can accept an input from an universal input and output the conditioned signal. It is powered by an 11-26 or 90-250 VDC /VAC supply. The universal input is fully programmable for Linear Voltage, Linear Current, PT100 and thermocouple types J, K, T, E, B, R, S, N, L, U, P, C, and D input. The input signal is digitized by using an 18-bit A to D converter. Its fast sampling rate allows the signal conditioner to retransmit the signal faster. It can do a maximum of 3 retransmission with one input.
The new generation of signal conditioner has a lot of unique features.
The unique features are listed below.
❖ Optional LCD Display
