features and benefits
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.
- Current Input, Voltage Input and Thermocouple Input
- Wider Input Range for Voltage
- 240 Vrms Overvoltage Protection
- Individual Channel Configuration
- Jumper Setting for Current or Voltage Measuring
- Open Thermocouple Detection
