The Allen Bradley 931S-V342 signal conditioner is a voltage measurement converter device with a voltage rating of 480 Volts AC. It is a 931 series device that is made for accurate signal conditioning. The converter is a 3-phase unit. It is equipped with a time delay option for alarm triggers. The device measures and monitors voltage and it enables a dedicated local display through signal splitting. It is equipped with 2 isolated relay outputs that can be configured for preset voltage measurements levels, phase asymmetry, phase losses, and phase angle errors. For input and output, the converter uses a single channel. The 931S-V342 signal conditioner has an input frequency of 40 to 60 Hertz. The input supply voltage is passive and powered by an input loop. The accuracy of the device is 3% of the rated voltage and the repeat accuracy is 2% of the rated voltage.

The 931S-V342 signal conditioner is equipped with an alarm function with top and bottom limit values, a window range, and an alarm delay. The holding function of the alarm can be activated automatically or manually. The converter is equipped with the latest transformer and optical technologies to accurately reproduce the signal. The converter eliminates the signal degradation of critical process measurement during transmission. The 931S-V342 signal conditioner has been rated to be used in a Pollution Degree 2 rated environment with an additional Surge Voltage Category III rating. The converter comes with an IP 20 protection rating and is not water resistant. The screw terminal torque of the converter is 0.6 N-m. The 931S-V342 signal conditioner comes with a removable terminal and error-proof keys. It is HART transparent and bidirectional in nature.
