Allen-Bradley 1771-RTP4 Analog Input Module

Description

The Allen-Bradley 1771-RTP4 Analog Input Module is part of the Allen-Bradley 1771 series of I/O modules, designed for integration with PLC systems. While direct technical specifications for the 1771-RTP4 are not available, it shares the 1771 series’ robust architecture, which is optimized for industrial signal acquisition and processing. For reference, other high-performance analog input modules in the 1771 series, such as the 1771-IXHR, offer key features that align with the series’ standards: 8 floating differential input channels, support for multiple thermocouple types (B, E, J, K, T, R, S) and millivolt signals, and a ±100 millivolt input range. These modules deliver high-resolution data with 1 microvolt millivolt resolution, 0.1 degrees Celsius or 0.1 degrees Fahrenheit temperature resolution, and ±0.5 degrees Celsius accuracy with cold junction compensation between 0 degrees Celsius and 60 degrees Celsius. They operate on 5V backplane power with a 750 mA backplane current draw, require no external power, and feature a 25 ms update time for all 8 channels, with a maximum power consumption of 4.255W and 14.5 BTU per hour heat dissipation. The 1771 series analog input modules convert analog sensor signals into digital data compatible with PLC processors, supporting direct data transfer to processor data tables and block transfer programming for configuration.
