SC4120A工业自动化与控制的延时继电器规格书PDF中文资料

描述 Description

The SC3/SC4 Series are solid-state 3 or 4 channel chasers

designed for sequential three circuit flashing of incandescent

lamp loads. Unlike electromechanical chasers, there are no

contacts to arc, wear, and eventually fail.

Operation

Sequential 3 or 4 circuit flashing of incandescent loads with

equal time delays for each load. Upon application of input

voltage, Load 1 is energized. At the end of the time delay, Load 1

de-energizes and Load 2 energizes. At the end of the time delay,

Load 2 de-energizes and Load 3 energizes. This cycle continues

until input voltage is removed. The set time delay (rate) is the

timing for the whole cycle, for all 3 loads (output contacts).

Reset: Removing input voltage resets the unit and cycle.
