Phase relay 16 A - Series 20
Series 20 available as DPST-NO or SPST-NO + SPST-NC latching relay. With each subsequent activation of the relay coil the contacts change state providing a sequence of steps or an operational "flip flop" sequence. Thanks to the test override button, it is possible to manually advance the sequence of steps, while the mechanical indicators give a visual indication of the status of the contacts. Typical applications include lighting control where engagement / disengagement or sequential operation is required, automatic opening / closing of doors, gates, and so on. Use in battery-powered or portable equipment that requires contact status to be maintained without continuous coil powering and for functions where manual override is desired
