This product is an 8-channel digital input and 16-channel digital output remote I/O module.The input channels of the module adopt optical optical coupling isolation, capable of receiving wide-range voltage signals from 5V to 48V. The output channels adopt 6 high-speed MOSFETs, which can directly control loads of the input voltage level to achieve efficient on-off control. Communicating with the main control system via the RS485 bus, this module can be stably applied in complex industrial environments, providing reliable distributed I/O solutions for scenarios such as equipment automation and production line control.
