Zamel Relays

zamel relays overview and range structure

This category covers pluggable relay solutions for signalling, interposing and small power loads in control panels and machine skids. Zamel structures the range by function (interposing, timing, power and monitoring), switching technology (electromechanical vs. solid-state), width class (6–22.5 mm), and coil set (12/24 V DC, 24/115/230 V AC). Typical buyers are panel shops, OEMs and MRO teams that want quick swap heads, bright status indication, and accessories that make mass wiring predictable. Fast movers are 24 V DC coils with integrated LED/diode, 1CO or 2CO contacts at 6–10 A, and slim 6–7 mm interposers for dense I/O rows.

Product range and series overview

• Slim interposers for PLC output adaptation and signal inversion.
• General-purpose pluggables in 12.5–14 mm with 6–10 A contacts.
• Compact power bodies up to 16–30 A for heaters and contactor pre-drive.
• Multifunction timers and voltage/level monitors in 17.5–22.5 mm housings.
  Most distributors stock relay heads in boxes of 10 and accessories—jumpers, clips, label carriers—in strip packs for line-side bins.

zamel interface relays for PLC adaptation

At 6–7 mm wide, these save rail space while adding coil suppression and clear LEDs for diagnostics. Typical duties: driving contactor coils from transistor cards, isolating field wiring, inverting logic, and protecting delicate outputs from inductive kick. Push-in bases speed assembly; screw bases help where conductor sizes vary. Cross-connection jumpers distribute a common across four to ten positions, cutting wiring time on light stack or valve islands.

Key ordering specs that matter

• Coils. 12/24 V DC (with diode) plus 115/230 V AC options.
• Contacts. 1CO/2CO, 6–10 A general use; gold-flash variants for low-level PLC signals.
• Indication and testing. Bright LED, optional test lever or mechanical flag.
• Accessories. Retaining clips for vibration zones, keyed bases to prevent mis-mating, printable label carriers.

zamel time relays functions and formats

Use timers wherever sequences and delays keep machines civilised: fan run-on, purge, pump alternation, flashing beacons, star-delta. Modes include on-delay, off-delay, interval, cyclic and star-delta, with 0.1 s to 100 h spans. Multifunction models with universal supply (24–240 V AC/DC) shrink spares and simplify service; fixed-mode versions lock behaviour where operators shouldn’t tweak settings. Clear scale marks and front LEDs help from the aisle during commissioning.

Applications and compatibility

Across conveyors, HVAC rooftops, bottling lines and test benches, these devices sit on TS35 rails next to power supplies and terminal blocks. Basket building is straightforward: add DIN rails, PE/earth terminals, ferrules, markers, wire duct and miniature breakers so assembly finishes in one pass. For entry hardware, match gland clamping range to jacket OD and plan shield clamps near I/O to keep noise off control lines.

zamel solid state relays for fast silent switching

Where speed, silence and life under high switching duty matter, SSRs are the pick. DC-DC versions handle solenoids and clutches without contact wear; AC SSRs drive heaters and small motors with zero-cross or random-fire options. Ratings typically span 1–25 A on natural convection; add fins when ambient runs hot. Expect finger-safe terminals, status LEDs and clip-in plates that align with common rail pitch. SSRs shine on high-cycle outputs and in dusty areas where arcing contacts would suffer.

Selection criteria for B2B clients

• Load and duty. Resistive vs. inductive changes contact material and size; leave 20% headroom for heat and cycling.
• Control voltage. Standardise on 24 V DC coils where possible; integrated suppression prevents nuisance trips.
• Form factor and width. Use 6–7 mm for dense interposing, 12.5–14 mm for general duty, larger bodies for >10 A.
• Environment. Vibration demands retaining clips; elevated ambient may require SSR heat sinks or spacing.
• Service model. Pluggable heads and keyed bases give five-minute swaps; keep two spares per frame size on each line.
• Bill completeness. Add jumpers, clips, markers and test plugs with every line—missing smalls cause build holds.

Integration with other Zamel and partner products

Bases share pitch with push-in feed-through terminals, so distributing 0 V or +24 V along a relay row is a seconds-long job with jumper bars. Marker carriers use the same print stock as your terminal markers; device IDs stay consistent from door plate to schematic. For cabinet entries, pair with EMC glands so shield continuity lands right at the gland and bonds on the adjacent PE bar.

Applications and field notes

Interposers live between PLC cards and the field, power relays sit behind contactors and small heaters, timers coordinate fans and alarms, and SSRs serve high-cycle devices or hot, dusty zones. Most returns trace to coil-voltage mix-ups or missing suppression on third-party bases—label coil voltage at the rail and standardise on DC coils with built-in diodes. In retrofit jobs we see nuisance trips vanish after moving timers away from VFD stacks and switching low-level loads to gold-flash contacts.

Procurement logic and fast movers

Stock the everyday trio: slim 24 V DC interposers with 1CO, 12.5–14 mm 2CO general-purpose heads, and a multifunction timer with universal supply. Add a small drawer of retaining clips, keyed bases and jumper combs—those parts rescue builds when vibration, mis-mating or common distribution bites. For projects with modular sub-plates, pre-assemble rows as zamel relay modules so installers land one code and wiring stays repeatable.

Expert commentary and buyer tips

Installers prefer push-in bases for speed on repeated layouts; maintenance likes mechanical flags for at-a-glance fault finding. Common substitution: swapping mechanical outputs to SSR where cycle counts exceed a few hundred thousand per year—noise drops, life rises. Keep one tray of gold-flash contacts for PLC-level signals; they stop intermittent inputs that burn time during FAT.
