Pump Sequence Relay The Electro 11 pin plug-in range of control and timing devices are to be installed into a standard 11 pin base making installation easy and convenient. Pump sequence module is designed to optimize the wear on pumps, compressors or generators. The first input energizes the first pump and stores this in non-volatile memory. Subsequent inputs will energize the next output. The number of its outputs correspond to the number of outputs. After power down or no inputs activated and an input is activated, the next in the sequence of outputs is activated. This ensures balanced usesage of the pumps because the same pump is not activated at the beginning of a sequence. Features: Three normally open pump outputs Permanent memory for next pump activated after power off Three normally open pressure switch inputs (voltage free) DESCRIPTION Pump sequencing relay CONTACT 3 x 5A SPDT NUMBER OF CIRCUITS 3 RATED VOLTAGE 250V MECHANICAL LIFE 10×106 cycles PROTECTION INDEX IP IP 20 OPERATING TEMPERATURE -10 to + 50°C STORAGE TEMPERATURE -50 to + 85°C DIMENSIONS (MM) (H) 92 x (W) 36 x (D) 64
