MK 330 GS
trip amplifier
The MK 330 GS trip amplifier compares the measurement signal at the input with the values set by means of the coding switches (0–99 %).
If the measurement signal exceeds or falls below the set value, the corresponding output relay responds according to the selected function (relay energises or de-energises).
