ALT115-X-SW繼電器的功率繼電器高于2A規(guī)格書PDF中文資料

Description

The ALT series alternating relays are used to alternate between

two loads. The ALT is commonly used in duplex pumping

applications to balance the runtime of both pumps.

The ALT-S is used in single high-level float applications. When

the float switch opens, the alternating relay changes state,

forcing the other pump to run the next time the float closes.

All ALT relays have a built-in debounce feature that prevents

the relay from changing state if the switch or float contact

bounces momentarily.

The ALT-X has an internal cross-connected relay and is used

in dual high-level float applications. These floats are commonly

referred to as lead and lag floats.

The pumps alternate as in the ALT-S version but the crossconnected

relay configuration allows both pumps to run

simultaneously when both the lead and lag floats are closed.

These relays are also available with a built-in switch (SW option)

that is used to manually force one of the pumps to run every

time the float switch is closed. This is helpful when a pump has

been removed for repair or for test purposes. In the case of the

ALT-X-SW, the switch essentially forces one pump to be the

lead pump, while still allowing the second to run when both

floats are closed.
