Product Description:

The X20 Fieldbus Input/Output series' high-accuracy resistance measurement module, B&R Automation X20RT8202, is made for automation control-related activities.

This module has two input channels and is designed to measure sensitive resistances. It has a number of measurement ranges (20 Ohm, 200 Ohm, 2 kOhm, 20 kOhm, 200 kOhm), so it will fit a large assortment of sensor type such as resistive sensors and RTDs. A 2-wire, 3-wire and 4-wire connection type is supported and the module is flexible as well as more accurate with applications. It achieves such output by having a 16-bit resolution with a conversion time of 500 ms per channel. The error is kept below 0.1 percent of the desired range to guarantee accuracy in signal acquisition to the quality controlling and monitoring requirements. Both channel to channel and channel to bus galvanic isolation is offered, an isolation voltage is 500 Veff. This increases safety of the system and guards the module against electrical disturbance and ground loops.

Input resistance is greater than 1 MOhm during voltage readings and aids the clean collection of signal even during expansive installments. It can only produce 24 VDC, and its power consumption of 0.4 W makes it a high-efficiency product, which is applicable in various segments like low-power, cost-effective industrial and automation applications. It can be mounted on DIN rail and has standard X20 modules dimensions of B&R, ensuring simple integration into an already implemented automation system. Its functionality is based on a -25°C to +60°C operating range with a 50 mating cycle rating at the bus-module/terminal-block connection. It can be purchased at Wake Industrial with a one-year warranty.
