I-87019RW features an extremely excellent protection mechanism where Overvoltage Protection is up to 240 Vrms. It has wider input range for voltage
compared to I-87018R. I-87019RW measures voltage from +/- 15 mV ~ +/- 10 V. Its input type also includes current and thermocouple. An intuitive design is kept in this model; choosing to measure current or voltage is simply by a jumper. An external resistor is no longer needed. Eight of its input channels can individually be configured with different kinds of analog input. What’s more, I-87019RW also got open thermocouple detection and many protection mechanisms. |
