Brief introduction: The paperless recorder is a kind of input signal that needs to be monitored on the industrial field, such as temperature signal of thermal resistance and thermocouple, flow signal of flowmeter, pressure signal of pressure transmitter and so on. Data processing is carried out by high-performance microprocessor. On the one hand, the data of these monitoring signals are displayed on the high resolution LCD screen in various forms, and on the other hand, the data of these monitoring signals are stored in the large-capacity memory chip inside the instrument for direct data and graphics query, browsing and printing on the instrument. Product features: Standard instrument size 160mm*80mm Monochrome LCD display, 320*200 resolution 4 universal signal input, mA, V, mV, TC, RTD, etc Supports thermocouple input cold end compensation High accuracy signal input One minute interval can record 180 days without loss of data for 10 years Channel high and low limit alarm, 4 relay contact output 1 channel 4-20ma current output, 1 channel 24VDC power distribution USB 2.0 port, support instrument data export Various data expression forms, number display, bar chart, curve Support channel accumulation, and support class, daily, monthly and annual reports Standard RS232C/RS485 communication interface, standard ModbusRTU protocol Configuration file backup export function Product parameters: Number of channels: 1-4 options Input signal: type II standard signal: 0-20ma, 0-5v, 0-10v, 0-10mv, 0-100mv Ⅲ type standard signal (4-20 mA, (1-5) V Thermocouples: S, R, B, K, N, E, J, T, F1, F2, wre5-26, wre3-25 Thermal resistance: Pt00, Cu50, Cu53, BA1, BA2 Analog signals: sine, cosine, square, triangle Special customization: vacuum, PT1000, frequency Power distribution output: 24V(standard) Analog output: 4-20ma (optional) Alarm output: up to 4 relay alarm output (optional) Accuracy: + / - 0.2% FS Input impedance: standard current signal input is 250Q.
