SUR-457
Meter with large, readable 57-mm LED display (ultra bright red, green and blue as well as multicolour LED’s), universal input (0/4-20mA, 0-10V, 0-150 mV, Pt 100/500/1000 or TC type K, S, J, T, N, R, B, E), 0, 2 or 4 relay (or OC type) outputs and 1 analogue output, according to the customer selection: active current output, passive isolated current output or active voltage output. Thanks to the tight housing with high (IP 67) protection degree, this device is particularly suitable for operations in harsh environments. The meter can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
