The isolated universal I/O module AR-403-IO-0404P features opto-isolated protection to protect output ports from interference and damage caused by input ports, thereby improving system stability and reliability.
It is suitable for various integrated applications that require high stability, such as automation control, security monitoring systems, and smart home control.
Electrical isolation
It can electrically isolate between input and output ports, effectively preventing electromagnetic interference and electrical short circuits.
High voltage protection
When the voltage of the input port exceeds the safe range, the opto-isolated protection function can isolate the high voltage to prevent damage to the output port.
Transient protection
In the case of momentary high voltage, the opto-isolated protection function can quickly isolate the input port to protect the output port from damage.
Support for four function modes
The AR-403-IO-0404P isolated universal I/O module supports four function modes that can be freely selected. With SOYAL CommView software, users can easily adjust the module's four function modes, including standard Modbus I/O, intelligent mailbox function, multifunctional output delay module, and direction identification for vehicle detection.

Output Format Support ON/OFF, Flash,and 500Hz PWM
Pulse width modulation (PWM) is a modulation technique that generates variable frequency and variable duty to represent the amplitude of an analog input signal.
The generated output can be set in pulse wave between 1ms to 510ms (recommended pulse is 255ms which is the most common pulse wave)
