    Small size current monitoring relay with built-in current transformer and integrated solid state output. Self-powered from the input current with 2-wire connection for easy setup. 12 mm hole for insulated current wire to easily insert the metered cable (multiple times if needed). For mounting on DIN-rail or back panel. GET A QUOTE

    DIA01 and PIA01 are precise AC/DC over current monitoring relays. Direct measuring or through current transformer. Owing to the built-in latch function, the ON-position of the relay output can be maintained. The red LED indicates the relay status. Through the built-in shunt it is possible to monitor loads up to 5 A AC/DC. GET A QUOTE

    DIB01 and PIB01 are precise TRMS AC/DC over or under current (selectable by DIPswitch) monitoring relays. Direct measuring or through current transformer. Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions). The...

    DIC01 and PIC01 are precise TRMS AC/DC over+under, over+over or under+under current and voltage (selectable by DIPswitch) monitoring relays. DIC01 can perform also DC plus/minus measurement by short circuiting pins Z3 and Y1. The devices can be connected to the MI or MP and A82 or E83 current transformers. Both relays have two individual set levels with...
