HTC230R paperless recorder for the three-channel universal input paperless recorder. Instrument can be configured to select the input standard current, standard voltage, thermocouple, RTD, frequency signal, providing the sensor distribution and four relay alarm output. Directly connected to micro-printer, print a user-specified time, historical data and curves; through the RS232 communication interface with the portable computer, handheld computer (PDA) connections, direct read meters historical data.
