Brainchild RSC Rail Signal Conditioner

The signal conditioner incorporates two bright easy to read LCD Displays which indicate Process Value (PV) and user-selected parameter. It is powered by an 11-26 or 90-250 VDC /VAC supply. It 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.
