The Allen-Bradley 1771-WS is a versatile weigh scale module from the 1771 series, engineered to efficiently interface with up to 8 load cells when powered externally. Designed for seamless data integration, it transfers calibrated values to a PLC-5 processor using block transfer protocols. Operating within an ambient temperature of 0 to 60 degrees Celsius and up to 90% humidity without condensation, this module ensures reliable performance, though it requires careful handling to avoid electrostatic discharge. With dual-color indicator lights on the front panel, the 1771-WS clearly signals Run/Fault and Calibrate/Communication operations, while depending on a stable power supply of 5 Volts DC ± 5% and supporting a continuous backplane input voltage of 40 Volts DC.
