Description
The Hikvision DS-PM1-O4L-H is a wired 4-way low-current relay expander designed for the Hikvision AX Hybrid PRO intrusion alarm system.
It provides 4 onboard relay outputs, allowing the AX Hybrid PRO control panel to control external low-voltage devices and circuits. Each relay supports 6–30V and can handle current of up to 5A.
The module communicates with the AX Hybrid PRO control panel using Speed-X technology and features both an uplink and downlink Speed-X port, allowing additional compatible expanders to be connected in cascade.
It also provides a dedicated power output of up to 500mA, while front and rear tamper protection helps protect the module against unauthorized access or removal.

Why Choose Hikvision DS-PM1-O4L-H?
The DS-PM1-O4L-H is ideal when an AX Hybrid PRO installation requires additional programmable relay outputs for controlling external equipment.
With 4 independent relay outputs rated up to 5A, the module can be integrated into alarm automation scenarios involving compatible low-voltage external devices. Speed-X connectivity and cascade support also make it easy to expand larger alarm installations. Hikvision
