4-point type, removable relay terminal Easy operation check by installing the operation indicator on the coil side Convenient to use by supporting DIN rail and screw mounting structure Easy wiring by using the built-in common bar, and the common bar between products (sold separately) can also be applied Relays are universal isolating elements used in the electrical industry with different requirements due to the versatility of the applications. Slim Relays for switching and control applications occupy about 6mm per channel. A relay is an electrically operated switch.
It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Terminal Block Relays are used between a controller (e.g. PLC) and a high-power load (a motor), mainly for 2 reasons: When a controller is not able to drive the load directly (due to different voltage requirements and insufficient driving current) For electrical isolation. These have two terminals which can be connected or disconnected. Including two for the coil, such a relay has four terminals in total. It is ambiguous whether the pole is normally open or normally closed.
