SP/V4 – 4-channel vibration protection and vibration diagnostics module

SP-V4

Vibration protection and vibration diagnostics SP/V4 module provides voltage or current measurement from the sensors in four measuring channels as well as has current outputs of slowly varying 4-20 mА signals and buffer analog outputs for control.

SP/V4 provides power supply for the sensors and protection from short circuit, supports various sensor connection schemes, at the same time providing control of current consumption and power supply voltage of the sensor.

To provide the function of phase marker input signal, any SP/V4 channel supports the sensor connection scheme according to NAMUR standard, thus executing control of open circuit, short circuit and position of the sensor output signal within the requested range.

Four relays (RELAY) of SP/V4 module are programmed for special alarm conditions for one or several channels. Alarms can be programmed on operation with or without fixation.
