931S-M5211

The Allen-Bradley 931S-M5211 smart current measurement converter is a signal conditioner from the Bulletin 193S smart converter product line that is designed to convert, measure, and monitor currents (AC and DC) rated at up to 10 Amps. The 931S-M5211 signal conditioner utilizes the True RMS algorithm for precise signal measurement even with distorted current waveforms, and it has a digital relay output that can be configured for conditions such as over-current and under-current situations. The 931S-M5211 signal conditioner has a voltage supply range of 16.8 to 31.2 Volts DC and a maximum power rating of 2.2 Watts. It has a voltage rating of 300 Volts AC (RMS) and a maximum impulse withstand rating of 6.4 kilovolts. The 931S-M5211 signal conditioner has an accuracy rating of 0.75% (of the full-scale range) and less than 300 milliseconds of step response time. It offers 4-way galvanic isolation between the input, the outputs (both analog and digital), and the power supply, and it has an isolation voltage rating of 4 kilovolts.

The Allen-Bradley 931S-M5211 signal conditioner has a single passive contactless through-hole input with an adjustable current measurement range of 0 to 5 or 10 Amps and an input frequency range of 15 to 700 Hertz. The 931S-M5211 signal conditioner has 2 active analog outputs with 0 to 20 or 4 to 20 milliamps of output signal current range and a load impedance rating of 600 Ohms. It also has one configurable changeover contact relay output with 6 Amps of maximum switching current and 250 Volts AC of maximum switching voltage. The 931S-M5211 signal conditioner has an IP 20 enclosure rating and an operating temperature range of -25  to 60 degrees Celsius. The 931S-M5211 signal conditioner weighs approximately 211 grams, and it has approximate dimensions of 0.89 x 4.7 x 4.47 inches.
