Hikvision Wired 4-Way Low Current Relay Expander | DS-PM1-O4L-H
The Hikvision DS-PM1-O4L-H is a wired 4-way low current relay expander for the Hikvision AX Hybrid Pro alarm system. It connects directly to a 6-30 V source and opens or closes each circuit on command from the control panel over the Speed-X bus. Each relay handles up to 5 A.
4 Low-Current Relays: Four on-board relays support 6-30 V and up to 5 A each. The control panel switches them on command, for example to control connected equipment when an event happens.
Power Output: One power output supplies 9 to 12 VDC at up to 500 mA for connected devices.
Speed-X Bus with Cascading: Two Speed-X ports, one uplink to the control panel and one downlink to the next expander, let you chain expanders as the system grows.
Tamper and Status: Front and rear tamper protection reports any attempt to open the module, and power and fault LEDs show its status. A TTL serial port is also provided.
Who it's for / Works with
The Hikvision AX Hybrid Pro control panel, over the Speed-X bus.
Good to know
Needs an 11 to 24 VDC, 1 A power supply.
Operating temperature is -10 °C to 40 °C, so the module is meant for indoor installation.
