The 931S-A481 smart configurable signal converter is a low-span signal conditioning device that is made by Allen-Bradley and designed to improve the signal quality from field devices to the control system. It offers low-span signal measurements and highly configurable input and output signals. The 931S-A481 signal converter can convert analog current and voltage signals, especially low range signals of about 4 milliamps and 2 Volts DC, and it offers a wide power supply range to accommodate a wide range of devices. The 931S-A481 signal converter has removable terminals with error-proof keys, and it offers easy configuration via DIP switches and onboard keys and a status indicator display. The 931S-A481 signal converter has a supply voltage rating of 12 to 60 Volts DC and a maximum power consumption of 3 Watts. It offers 2 kilovolts of galvanic voltage isolation between the input, the output, and the power supply, and it has an impulse withstand voltage rating of 4 kilovolts.

The Allen-Bradley 931S-A481 signal converter has an active/passive input with configurable input signal ranges of 0 to 22 millAmps or 0 to 11 Volts DC, and with an input resolution of 3.5 microamps or 1.76 milliVolts per bit. The 931S-A481 signal converter also has a single, active output with an adjustable analog output signal range (0 to 22 milliamps or 0 to 11 Volts DC) and a resistance rating of kiloohms (at the current output). The 931S-A481 signal converter has a typical accuracy range of ± 0.05% and a step response time of 350 milliseconds. It has an IP 20 environmental protection rating and an operating temperature range of -20 to 60 degrees Celsius. The 931S-A481 signal converter has approximate dimensions of 0.49 x 4.58 x 4.47 inches and an average shipping weight of 80 grams.
