eYc DST01 Universal Isolating Signal Converter / Splitter
| Previous | 1 / 11 | Next |
Signal isolation：Power supply；Analog input
3 groups of analog output
1 set RS-485 output
Accuracy：±0.05% of span ±0.0025% / °C
Output signal：4 ... 20 mA, DC 0 ... 10 V
Description
DST01 The signal conditioner incorporates two bright and easy to read LCD displays which indicate process value (PV) and user selected parameter.
Powered by a DC 12 ... 38 V or AC 95 ... 250 V supply. It is fully programmable for linear voltage, linear current, Pt100 and thermocouple types such as J, K, T, E, B, R, S, N, L, U, P, C, and D input. Its fast sampling rate allows the signal conditioner to retransmit the signal faster, the maximum of 3 retransmission with one input.
