931S-B481

The Allen-Bradley 931S-B481 smart strain gauge converter is a signal conditioning device from the Bulletin 193S product series that is designed to improve the signal quality in signals from field devices to control systems. This device can also convert measurement data from devices like weighing scales, strain gauges, Wheatstone bridges, load cells, and resistance measuring bridges into standard analog voltage/current signals, and it offers enhanced and configurable input and output signals. The 931S-B481 signal conditioner offers field-removable terminals with error-proof keys, and it also offers easy configuration via its onboard pushbuttons and DIP switches. The 931S-B481 signal conditioner has a supply voltage range of 10 to 60 Volts DC and a maximum power consumption rating of 3 Watts at 24 Volts DC.

The Allen-Bradley 931S-B481 signal conditioner has 1 active input with ± 10 millivolts, ± 20 millivolts, ± 30 millivolts, or ±50 millivolts of input measurements and a sensor supply rating of 120 milliAmps at 10 Volts DC. The 931S-B481 signal conditioner has a single active output channel with adjustable output signal ranges of 0 to 22 milliAmps and 0 to 11 Volts DC and a load impedance rating of 600 Ohms. It has an accuracy of 0.05% of the full-scale range (FSR) and a step response time of fewer than 400 milliseconds. The 931S-B481 signal conditioner offers 3-way galvanic isolation between the input, output, and the power supply, and it has an isolation voltage rating of 5 kilovolts. The 931S-B481 signal conditioner has an IP 20 ingress protection rating and an operating ambient temperature range of -40 to 70 degrees Celsius. The 931S-B481 signal conditioner has an average weight of 176 grams and approximate dimensions of 22.5 x 119.2 x 113.6 millimeters.
