Hikvision Wireless Relay Module | DS-PM1-O1L-WB
The Hikvision DS-PM1-O1L-WB is a wireless relay module for the Hikvision AX PRO alarm system that switches low-voltage electrical power. It runs from a 7 to 24 VDC supply and its relay output (NO/NC) handles 0 to 36 VDC at up to 5 A. You can switch it from the app, keypad or keyfob, or let it switch automatically on system events, over 433 MHz two-way wireless with up to 800 m range.
Color: White

Key Features:
One-Button On/Off: The relay can be turned on or off with one button from the app, a keyfob or a keypad, giving you remote control of the connected low-voltage circuit.
Event-Based Scenarios: Scenarios can switch the relay automatically by alarm, by operation, by fault, by schedule or manually. For example, the relay can follow an alarm event or run on a set schedule.
Secure Two-Way Wireless: It communicates with the panel over 433 MHz two-way wireless with AES-128 encryption and up to 800 m RF range.
Clear LED Status: Three LEDs show register/signal (green/red), power (green) and relay status (blue), so you can see at a glance whether the module is registered and whether the relay is on.
Tamper Input: One alarm input for tamper supports NO or NC wiring, for connecting an external appliance's tamper contact.
Small Case: The compact 38 × 25 × 18 mm case (28.5 g) can easily be put in hiding places.
Works with: Hikvision AX PRO wireless alarm systems.
Good to know: The module needs a 7 to 24 VDC power supply. The relay output is rated for low-voltage DC loads (0 to 36 VDC, max 5 A).
