Voltage Presence Detector

ProLine P 52000 VPD

Railway and Industrial Application Solution for Monitoring Voltages from 50 - 4200 V AC/DC

ProLine P 52000 VPD detects the presence of voltage. The input signal is compared to a threshold value and the resulting binary information is galvanically isolated and transmitted to the output circuit. When the input voltage exceeds the set threshold value, a solid state relay opens, signaling the presence of voltage at the input.

The signal of the solid state relay can control a hardware relay, for example, or be fed into a safety device or controller. The signal levels are based on type 1, EN
61131-2 PLC signal inputs.

The threshold value applies regardless of the sign of the input voltage’s absolute value. In other words, the solid state relay will be triggered as soon as the positive threshold value is exceeded or the input voltage is below the negative threshold.

10 default threshold values can be selected using the rotary switch on the front of the device. Units with user-defined values are also available.
