Our 3in1 pump alternating relay offers the most capability in the industry’s most compact and space-saving DIN-Rail enclosure style. TELE’s duplexer controls two loads simultaneously while enhancing the regular alternating function through integrated ON and OFF Delay functionality. The selector switch allows the user to lock in one sequence while the relay works with a wide range control voltage of 24 – 240V AC/DC. The E1ZMLA is commonly used in special applications where the optimization of load usage is required by equalizing the run time of two loads. Identical loads are used for the same job—one or more standby units are available in case the first load fails. However, an idle load might deteriorate due to lack of use and provide no safety margin. Alternating relays prevent this by assuring that multiple loads get equal run time. In addition, there are situations where a need arises to have multiple loads on at the same time for additional capacity if one load cannot keep up with demand. This alternating functionality “LA” is initiated by a control switch, such as a float switch, manual switch, timing relay, pressure switch, or another isolated contact. Each time the initiating switch is opened, the output relay contacts will change state, thus alternating the two loads. Two LED indicators show the status of the output relay, control voltage and timing function.
