The Allen-Bradley 1771-IRK PLC-5 RTD is a high-performance I/O module designed for precision, offering up to six three-wire RTD inputs with a resolution of 50ms per eight channels and a 16-bit plus sign precision for both Celsius and Fahrenheit readings. It operates efficiently without an external power supply, drawing 800 mA backplane current, and supports 100 Ohm platinum and 10 Ohm input ranges for low-voltage conditions. Its conformal coating protects the device from environmental factors like dirt and moisture, ensuring reliable performance, while the included plastic keying bands allow flexible configuration and status indication within the 1771 I/O chassis.
