Description
Advanced automation for greater safety
MultiRelay Fibra is a relay module designed to implement complex wiring diagrams. It has four relays with potential-free (dry) contacts that can control four separate circuits independently. MultiRelay can integrate various appliances, electrical mechanisms and even third-party security devices into the Ajax system. With Ajax scenarios, the module provides fully automated actions in response to alarms and security mode changes or performs them by a specified schedule.

Smart security and comfort
Use automation scenarios to make life safer and more comfortable. Set your office lights to turn off automatically on arming. Program your projectors to turn on when outdoor motion detectors identify intruders. Or turn on your toaster at a certain time in the morning.
4 separate circuits control
The module has four relays that can control four separate circuits independently, meaning it can maintain four different appliances or electric mechanisms. Automation scenarios can be configured for each relay separately. Also, several relays can be connected to control one device if required by the wiring scheme.
Impulse and bistable modes
Each relay supports two operation modes:
- Bistable — the relay changes contact state after each activation, turning the connected appliance on or off.
- Pulse — the relay changes contact state for the adjustable time (from 10 s to 2 h).
The mode can be configured in Ajax apps for each relay separately.
Steady contact state
The device retains the current contact state of a relay. After a power loss and subsequent restoration, the contact state remains unchanged. The feature can be activated in Ajax apps for each relay separately.
Support for both AC and DC circuits
The module has relays with potential-free (dry) contacts and can control circuits with direct, alternating, or no current.
Configurable NC/NO contact states
Each relay supports two contact states:
- Normally closed (NC) — the relay stops supplying power when activated and resumes when deactivated.
- Normally open (NO) — the relay supplies power when activated and stops when deactivated.
The normal contact state can be configured in Ajax apps.
