Comet U6841 用于3个电流输入0-20mA和1个两态输入的数据记录器 (Lithium 3.6V, AA)

Measured value: Current, Two-state signal

Current input:

  Measuring range: 0 to 20 mA DC

  Resolution: better than 1 µA

  Accuracy: ±20 µA

  Input resistance: approx. 100 Ω

  Minimum current: 0 mA (open circuit)

  Maximum current: limited to approx. 40 mA

Binary input:

  Parameters of the voltage contact: "L" level input voltage:< 0,8 V(*);

                                                         "H" level input voltage:> 2 V;

                                                          Minimum voltage applicable:0 V;

                                                          Maximum voltage applicable:+30 V DC

Parameters of the voltage-free contact: Contact resistance in "switched-on" state: < 10 kOhm;

                                                               Contact resistance in the "switched-off" state: > 2 MOhm;

                                                               Contact voltage in the "switched-off"  state: ca 3 V;

                                                               Minimum state duration necessary for latching the state: 1s

Operating temperature: -20 to +60 °C

Channels: 3x current input, 1x binary input

Memory: 500 000 values in noncyclic logging mode; 350 000 values in cyclic record mode

Recording interval: adjustable from 1 s to 24 h

Display and alarm refresh: adjustable 1 s, 10 s, 1 min

Recording mode: noncyclic - data logging stops after filling the memory
