931S-L521

The Allen-Bradley 931S-L521 smart current measurement converter is a signal conditioner device from the Bulletin 193S signal conditioner product family that is designed to measure and monitor AC and DC currents of up to 10 Amps via the True RMS sensing algorithm. This device offers both analog and digital output options and it provides the operators with a cost-effective means of monitoring and converting current measurements. The 931S-L521 signal conditioner can be configured with either a DIP switch or potentiometer, and it comes with an IP 20 protection rating. The 931S-L521 signal conditioner has a voltage supply range of 16.8 to 31.2 Volts DC and a maximum power consumption of 2.2 Watts. This device has a galvanic isolation rating of 4 kilovolts between the input, the outputs, and the power supply, and it has an impulse voltage withstand rating of 6 kilovolts.

The 931S-L521 signal conditioner has an accuracy range of ±0.3% at 1 Amp and ≤±0.6% at 10 Amps, and it has a step response time of 300 milliseconds. The 931S-L521 signal conditioner has a configurable passive input channel with an adjustable input range of 0 to 1/5/10 Amps (AC or DC) and an input frequency range of 15 to 400 Hertz (RMS). It has 2 active analog outputs with adjustable output signal ranges of 0/4/-20 to 20 milliAmps and -5 to 5 Volts/-10 to 10 Volts, and a load impedance of up to 10 kiloohms. The 931S-L521 signal conditioner also has a configurable digital relay output with an inverse adjustment and maximum switching current of 2 Amps. The 931S-L521 signal conditioner has approximate dimensions of 17.5 x 117.2 x 113.6 millimeters and an average shipping weight of 141 grams.
