Hikvision Wireless Relay Module | DS-PM1-O1L-WB
The Hikvision DS-PM1-O1L-WB is a wireless relay module that controls a low-voltage electrical power supply. It is powered from 7 to 24 VDC and opens or closes a circuit manually from the app, keypad or keyfob, or automatically by linking to system events. It also has a tamper alarm input and communicates over two-way 433 MHz wireless with up to 800 m range.
Key Features
Switch Low-Voltage Loads: The NO/NC relay output switches 0 to 36 V DC loads up to 5 A. You can turn it on or off with one button from the app, a keyfob or a keypad.

Automation Scenarios: Scenarios can be set by alarm, by operation, by fault, by schedule or manually. The relay can therefore react to system events or follow a schedule without anyone pressing a button.
Alarm Input for Tamper: One alarm input (NO/NC) is provided for a tamper connection from external appliances. This lets the system report if the connected equipment is tampered with.

Compact Design and Status LEDs: The 38 x 25 x 18 mm case weighs 28.5 g and can be put into hiding places easily. Three LEDs show register/signal (green/red), power (green) and relay status (blue).
Secure Two-Way Wireless: The module communicates over two-way 433 MHz wireless with AES-128 encryption. The RF distance is up to 800 m.
Who it's for / Works with
Hikvision AX PRO 433 MHz wireless alarm systems; controlled from the app, a keypad or a keyfob (control panel sold separately).
Good to know
- It needs a 7 to 24 VDC power supply (not mains). The relay output is rated 0 to 36 V DC, max. 5 A.
