After a command is issued, the switching module action time is within 2ms, and the reset time is within 1ms.
Switching times are not less than 10 million.
Supports I/O signal control or RS232 communication control to meet the control needs of various customer systems.
Precise calculation of internal circuit impedance and multi-faceted anti-interference measures.
Comes standard with a DC24V power adapter for power supply, the maximum operating current does not exceed 1A, and the power supply has a reverse connection protection function, which can effectively protect the switching system.
