Why Choose the ABB E294/24 Central On-Off Control Module?
The ABB E294/24 is a compact central ON/OFF control module designed for use with compatible ABB E290 latching relays in building control, lighting and electrical distribution applications. As part of ABB's modular control range, it enables central switching commands to be incorporated into impulse-controlled installations from a common control point.
The E294/24 is particularly useful where several latching relay circuits need to be switched centrally while retaining their individual local control functions. This allows installations such as multi-zone lighting systems to provide convenient master ON and OFF commands alongside normal push-button operation of individual circuits.
Designed for a 24 V AC control supply, the E294/24 provides a practical modular solution for centralised control in residential, commercial and industrial installations. Its DIN rail format enables straightforward integration alongside compatible ABB switching and control devices inside electrical distribution boards.
Key Advantages
- Dedicated central ON/OFF control module for compatible ABB latching relay systems.
- 24 V AC control voltage for low-voltage control circuits.
- Enables convenient master switching of multiple controlled circuits.
- Supports central control while maintaining individual local switching functions.
- Modular design for straightforward integration into electrical distribution boards.
- DIN rail mounting for compact and organised panel installation.
Key Features
- ABB E294 central ON/OFF control module.
- 24 V AC rated control voltage.
- Designed for central ON and OFF commands.
- Suitable for use with compatible ABB E290 latching relays.
- Supports centralised control of impulse-switching installations.
- Suitable for lighting and building-control applications.
- Modular construction for distribution-board installation.
- DIN rail mounting with screw-terminal connections.
Centralised Control for Latching Relay Installations
Central ON/OFF modules such as the ABB E294/24 extend an impulse-switching installation by providing common master commands. Individual latching relays can continue to control their respective circuits locally, while the central control function provides a convenient way to place connected circuits into a defined ON or OFF state from one location.
This functionality is particularly valuable in larger lighting installations, where individual rooms or zones require independent control but a central command is also needed. Typical examples include switching multiple lighting circuits off when leaving a building or applying a common control command across several zones.
Typical Applications
- Central ON/OFF control of lighting circuits.
- Residential and commercial building automation.
- Multi-zone lighting control systems.
- Electrical distribution boards.
- Impulse-controlled latching relay installations.
- Central master switching in compatible ABB E290 relay systems.
