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 led's indicate the state of the alarm and the output relay. Through the built-in shunt it is possible to monitor loads up to 10 a ac/dc.

Monitoring Relays DLA71 is relay made to alternate 2 or 3 pumps in a multiple pump system. In case of need (i.e.: overflow) the second, or even the third pump can be activated together with the first one. In case more than one pump is required to start at the same time, the pumps start 10 s after the previous to avoid big inrush current. The LED indicates the state of the alarm and the output relay. 35.5 mm wide housing suitable both for back and front panel mounting.

Features:

• Pump alternating relay for 2 or 3 pumps.
• Output: 2 x 5 A SPST relay or 3 x 5 A SPST.
