Industrial Relays & Timers — Precision Switching for Every Control Application

When it comes to industrial relays and timers, AMPS stocks what you need and knows how to apply it. We carry Finder — founded in 1954 with over 70 years of specialized manufacturing expertise and more quality certifications than any other relay manufacturer in the world. With a catalog spanning more than 14,500 products, Finder is the go-to relay brand for engineers who can’t afford downtime.

Industrial relays and timers are fundamental building blocks of control panel design — managing switching, isolation, timing sequences, and signal interfacing across machines, processes, and automation systems.

WHAT THEY DO

Switch and isolate control signals
Interface PLC outputs to loads
Time sequences and automation cycles
Provide silent solid-state switching
Operate in hazardous locations (ATEX)

COMMON APPLICATIONS

PLC output isolation and signal conversion
Timing and sequencing control
Temperature and process control
Panel building and machine control
Railway and hazardous location applications

Industrial Relays

Finder’s lineup covers miniature general purpose relays, plug-in power relays, interface relay modules, and specialty relays. The 55 and 56 Series miniature relays offer 7–10A general purpose switching; the 90–99 Series covers larger plug-in power relays; and the 46 Series provides miniature industrial relays suitable for railway and demanding applications.

What Finder Industrial Relays Offer

Miniature general purpose relays (55, 56 Series) for compact panel builds
Plug-in power relays (90–99 Series) for higher current switching
Interface relay modules for PLC output isolation and signal conversion
Relay modules with forcibly guided contacts (7S Series) for safety
ATEX/IECEx/HazLoc rated versions for hazardous location installations
Wide selection of coil voltages and contact configurations

Solid State Relays

Finder’s SSR lineup provides semiconductor switching with no moving parts — ideal for high switching frequency, long electrical life, and silent operation. The 77 Series modular SSRs (5–50A) are DIN-rail mounted; the 34, 38, and 39 Series compact interface SSRs are designed for direct PLC output interfacing.

What Finder Solid State Relays Offer

No moving parts — silent operation with no contact wear
Zero-crossing and random switching modes
High switching frequency for temperature and process control
Modular DIN-rail SSRs from 5A to 50A (77 Series)
Compact interface SSRs for direct PLC output connection
Long electrical life — approx. 100× that of electromechanical relays

Timing Relays

Finder’s timing relay lineup spans from simple single-function timers to sophisticated multifunction programmable devices. The 80, 81, and 83 Series offer multi-voltage modular timers; the 84 Series SMARTimer provides advanced multifunction capability; the 85 Series covers miniature plug-in timers; and the 86 Series offers modular DIN-rail modules.

What Finder Timing Relays Offer

Single-function and multifunction programmable timers
On-delay, off-delay, interval, star-delta, and many other timing modes
Wide time range from 0.1 seconds to 24 hours
Multi-voltage designs accepting a wide input range
Modular DIN-rail and plug-in mounting options
Compact miniature versions for space-constrained panel builds
