Interface and impulse relays

Interface and impulse relays are selected by the specific type, control version and contact configuration. Separate the relay from its socket, base and retaining accessories when comparing offers.

Choose the right relay area

The range includes interface relays and relay modules, impulse versions and separate bases or sockets. The general name “relay” does not make these products one and the same item. Retain the type and series in the search. For a kit with a separate socket, establish exactly which element you receive and which additional parts are required.

An impulse version is considered separately from an interface relay with a base. If the aim is another task, use monitoring relays or time relays and timers. Do not treat an externally similar housing as confirmation that different relay types operate identically or can be replaced without checking.

The coil and contacts have separate data

The range distinguishes AC and DC control designations, different contact configurations and modular formats. For the chosen model, clarify which part every documented value concerns. Do not mix coil data with contact data. Similar numbers on two items do not establish identical control versions.

Compare the exact contact configuration with the task required, including NO and NC designations where stated. Also check the specific relay module's contents. An indicator in one offer does not mean identical indication across all series variants. Colour is secondary to relay type, control and contacts.

Select the socket and accessories as a system

Individual items include retaining clips, bases and diode accessories. Compare these by the relay's exact series and reference. Check mounting, space occupied and included contents instead of assuming any base is suitable. For a replacement, retain both the relay code and existing socket code if it remains. Explicitly compare the contents of every kit.

For the areas presented, explore ABB and WAGO. The general relays and timers section helps distinguish functions before the final choice. Prepare a separate list of the relay or module, base, fixing and accessories required; one item should not be treated as the entire set solely from a photograph.
