Why Choose the ABB E295-PS Permanent Signal Module?
The ABB E295-PS is a compact permanent signal module designed as an accessory for ABB E290 electromechanical latching relays. It enables a compatible impulse relay to be controlled using a continuous electrical signal rather than only a momentary push-button impulse, extending the flexibility of latching relay installations in lighting, building control and automation applications.
When a continuous signal is applied, for example from a timer, twilight switch, motion detector or control relay, the E295-PS interfaces that signal with the associated latching relay. This allows automatic control devices with maintained outputs to operate an impulse-switching system without requiring a separate momentary pulse interface.
The E295-PS is rated for 1 A and 250 V AC and is designed for DIN rail installation alongside compatible ABB E290 equipment. Its compact modular construction and wide -25 to +55 °C operating temperature range make it suitable for integration into electrical distribution boards and building-control panels.

Continuous-Signal Control for Latching Relay Systems
Conventional latching relays normally change their contact state in response to short electrical impulses. The ABB E295-PS expands this functionality by allowing a compatible latching relay to respond to a maintained control signal, making it easier to integrate impulse switching with automatic building-control devices.
This functionality is particularly useful when an ABB E290 latching relay is controlled by equipment such as a timer, twilight switch, motion detector, relay or time relay that provides a continuous switching signal. When the E295-PS is fitted, the latching relay's manual operating lever is covered, so manual operation of the impulse relay is not available while the permanent signal module is installed.
Typical Applications
- Automatic lighting control systems.
- Timer-controlled latching relay circuits.
- Twilight and daylight-dependent switching.
- Motion detector controlled lighting.
- Building automation and electrical distribution boards.
- Continuous-signal integration with ABB E290 latching relays.
