G3TA-OA101SZ-1 DC24

G3TA-OA101SZ-1 DC24 is one kind of I/O Relay Modules, which is extensively used in various industrial automation application fields. It combines an electromechanical relay with an output transistor drive in the same housing. And G3TA-OA101SZ-1 DC24 can provide a functional breakdown voltage of 24V and rated output load of 2A. This I/O Relay Modules prominently simplifies the control circuit diagram without otherwise reducing the safety and reliability of the entire system.

This G3TA-OA101SZ-1 DC24 I/O Relay Modules is composed of an electric switch (input) and a control transistor (output). During its normal running process, the relay coils and contacts contain the logic control portion, and the output part is driven by a control transistor. Its dual-purpose design can improve the reliability of the output terminal “off” state.

Application Field

G3TA-OA101SZ-1 DC24 I/O Relay Modules can be used to control the on/ off of load power and is applicable to a wide range of industrial automation fields, including electric drive, automation control, robot devices, and heat control systems, etc

Working Principle

The working principle of G3TA-OA101SZ-1 DC24 I/O Relay Modules consists of three parts. The first is an input switching power supply, which is the direct current voltage input source of the Module. The second part is a coil connected in series with the contact, which acts as a signal isolator. When an external control signal turns on, a current is conducted through the coil, thereby generating a magnetic field in it. The third part is a control transistor, which acts as an output port.

Via the aforementioned working principle, the energy is conducted from the input to the output through the switch of the relay, which causes the coil to generate a magnetic field. Since the output relay module can switch certain specific current under this magnetic field, it can effectively prevent the current exchanging between the power supply and the load, and achieve the normal operation of the designated on/off.
