ifm electronic relays for control, safety and interface applications
When you’re specifying relays for machine control, safety circuits or interface switching, the choice of relay technology is more than “just a switch”. ifm electronic relays – interface relays, solid-state relays, control relays – bring industrial-grade reliability, integration into automation systems and serviceability through their life-cycle. In practice you’ll see these relays used on conveyor systems, machine safety guards, PLC outputs, panel retrofit jobs and OEM switchgear where downtime, compatibility and maintenance count.
ifm Interface relays, solid-state relays and control relays
From hands-on project work, when we talk about “ifm electronic relays” we’re referring to a set of functional blocks including:
- Interface relays: modules that shift low-level control signals (PLC output) to higher loads, provide galvanic isolation and simplify wiring. For example, the AC2411 compact interface relay module by ifm handles M12 inputs.
- Safety relays and control relays: units designed to monitor safety inputs (E-stop, light curtain) and switch machine circuits accordingly. The safety-relay category on the ifm website outlines use-cases such as standstill monitoring, light-grid muting, etc.
- Solid-state relays: semiconductor-based switching devices without mechanical contacts. Modern automation increasingly uses SSRs for longer life, silent switching and high-frequency cycling. Industry analysis shows SSRs offer longer life and lower maintenance than mechanical relays.
- Relay accessories and modules: sockets, mounting rails, adapters (e.g., DP1603 relay adapter by ifm with IP67 rating) that support flexible installation.
For procurement logic: you’re not just ordering a “relay”, you’re acquiring a switching platform that must match coil voltage, load type, control system interface, safety certification and mounting form-factor.
Key technical and procurement considerations for relay specification
From real industrial panel builds and machine installations, here are the specification parameters and buying logic you’ll want to verify:
- Coil/control voltage: Does the relay match your PLC or sensor output (for instance 24 V DC) and the load side (230 V AC, 24 V DC, etc)? Ifm’s range includes control modules tailored for mobile machines and harsh environments.
- Contact/load type and rating: Ensure the relay contacts or solid-state output can handle your switching current, load nature (resistive, inductive, motor), cycle frequency and ambient temperature.
- Interface type and control logic: For interface relays, confirm compatibility with your automation bus, IO-Link or discrete wiring; for safety relays, confirm certification (e.g., category 3/4, PL e in Eurosystems).
- Mechanical and mounting compatibility: Panel space, DIN rail vs base mount, accessory modules, IP rating. The correct adapter or mounting kit (like ifm’s adapters) can drastically speed up installation.
- Reliability, lifecycle and maintenance logic: Solid-state relays (SSRs) avoid mechanical wear yet may need heat-sinking; mechanical relays might be lower initial cost but higher maintenance. Industry sources emphasise TCO (total cost of ownership) when comparing EMR vs SSR.
- Standardisation and supply chain logic: From procurement perspective choose one or two families of relays that cover most switching needs (interface, safety, general control). That simplifies spares, training and stock-holding.
In practice, you’ll usually see commissioning delays when the wrong relay voltage or mounting style arrives, or when spare stock is lacking; standardising and ordering proactively avoids those issues.
Wholesale procurement logic for ifm relays
As a procurement manager planning bulk orders for a machine build or line-installation, here’s a straightforward approach:
- Select core relay families: Choose one interface relay (module style), one safety/control relay style, one solid-state relay style — these three families will cover ~80 % of switching tasks.
- Standardise specifications: For example pick 24 V DC coil/control, one load rating (e.g., 10 A at 230 V AC) for your general switching tasks, and one mounting footprint.
- Order spares and accessory kits: Because relays are parts that may fail or need replacement, include ~10% spare units per family. Also order related accessories (sockets, adapters, mounting hardware) at the same time.
- Bundle kits for panel builds: Package the relay plus mounting hardware plus wiring terminals as a kit for each panel; this simplifies installer hand-over and reduces missing parts on site.
- Use standard part numbers and batch tracking: Because relays may change revision or manufacturer code, keep a procurement sheet with part numbers and preferred manufacturer (ifm) so re-order is consistent.
By applying this logic you improve installation readiness, reduce downtime risk, and maintain consistent parts across multiple builds or sites
Why choosing ifm electronic relays makes sense for industrial projects
When you deploy panels or machines across multiple sites or production lines, consistency and quality matter. Choosing ifm for your relays means you get trusted supplier quality, full automation-grade integration, standardised mounting and wiring, fewer mixed vendors and simpler spare-parts logic. For procurement that means predictable supply, fewer part variants, easier training. For installers it means familiar hardware, mounting and wiring practices. Over time this simplifies maintenance, speeds commissioning and improves life-cycle cost control.
