Zelio Control Relays
Near Field Communication (NFC) and conventional Control Relays
Part of Harmony
These control relays monitor and detect abnormal operating conditions (phases, current, voltage, frequency, speed, or temperature). They also control liquid levels and process operating rate. Available in conventional dials or NFC.
