The digital output module is an electronic device, DO810 3BSE008510R1 is used to send the BOOL type data 0 or 1 of the logical result of the controller program operation to the outside of the module channel to be converted into an external drive signal, and open or close the external switch through the module terminal loop. It can convert the internal signal level of the PLC into the external signal level required for the control process, and has the effect of isolation and power amplification.

The output circuit of the digital output module is generally equipped with a RC filter circuit, DO810 3BSE008510R1, to prevent the wrong input signal caused by the input contact jitter or external interference pulse. The power amplifier elements of the output module are high-power transistors and field-effect transistors that drive DC loads, bidirectional thyristors or solid-state relays that drive AC loads, and small relays that can drive both AC and DC loads.

When selecting a digital output module, attention should be paid to the type and size of the load voltage, the operating frequency and the type of load (resistive, inductive, mechanical or incandescent loads). The DO810 3BSE008510R1 digital output module is widely used in various occasions where external equipment needs to be controlled, such as engine starting, hydraulic tilt valve, engine cooling fan in the automatic control system of sand mixer.
