Description
The Hikvision DS-PM1-O4H-H is a wired 4-way high-power relay expander designed for the Hikvision AX Hybrid PRO intrusion alarm system.
It provides 4 onboard power relay outputs, allowing the AX Hybrid PRO system to control higher-power electrical loads and external devices. Each relay can handle current of up to 16A, making this model suitable for applications that require significantly higher switching capacity than a standard low-current relay expander.
The module communicates with the AX Hybrid PRO control panel through Speed-X Bus and includes both an uplink and downlink Speed-X connection, allowing compatible expanders to be connected in cascade for larger installations.

Why Choose Hikvision DS-PM1-O4H-H?
The DS-PM1-O4H-H is designed for AX Hybrid PRO installations that require the alarm system to control higher-power electrical devices.
With 4 independent power relays rated up to 16A each, it offers significantly greater switching capacity than the low-current DS-PM1-O4L-H. Speed-X connectivity and cascade support also make it suitable for larger residential and commercial automation and security installations.
