Hikvision AX PRO Bus input expander, 4 relay outputs

The wired four-way power relay expander offers reliable control of connected devices through four built-in relays. Each relay supports a load of up to 16 A at 230 V AC or 5 A at 30 V DC, allowing for the control of a wide range of electrical appliances and other devices. Communication occurs via the RS-485 serial interface.

Support for bus distance extension expands installation options and facilitates integration into larger systems. Tamper protection on both the front and back sides contributes to higher device security. The panel design allows integration into a suitable system, and clear LED indication provides quick visual monitoring of operational status.
