About Timer Relays

Solid State Spade-Terminal Relays
Often used for high-speed switching at low-current levels, these solid state relays have no moving parts, so they switch faster, last longer, and are quieter than mechanical switches.
Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation.
Relay sockets with screw terminals can also mount to a flat surface.


DIN-Rail Mount Solid State Interface Relays

With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relays disconnect from the socket for easy replacement. Rated IP20, they prevent fingers and other objects from touching live circuits.

Circuit Board Relays

Smaller than relays with electrical wiring, these relays fit in compact devices. Mount them through holes on circuit boards with their solder pin terminals. Use them to control heaters, fans, and other high-power components from a low-power circuit.
Solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter than mechanical relays.

Solid State Screw Terminal Relays


With no moving parts, these solid-state relays are fast switching and require less maintenance, last longer, and are quieter than mechanical switches.
Heat sinks disperse heat to increase the relay’s current rating. Mount them to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces. Before mounting one-circuit relays, silicone compound or a thermal pad should be placed between the heat sink and relay. Silicone compound is sold separately for heat sinks that do not include it but require it. Two-circuit relays don’t require silicone for mounting.

Safety Relays with Diagnostic Capabilities
Control and diagnose issues with safety-critical circuits. These relays have a microprocessor that monitors safety components, such as emergency stops and light curtains, and sends a signal to stop the operation if a failure is detected and restart when the issue is resolved. They also help with diagnostic tasks because of their feedback circuit, which allows basic relays to communicate their status back to the safety relay. These relays have a duplicate set of input and output signals, so they’ll still stop the controlled device if one of the inputs fails.
IP20 rated, they have recessed terminals which prevent fingers and other objects from touching live circuits. These relays have been tested to multiple safety standards and can help achieve PL, SIL, or CAT system ratings. They also meet ISO and IEC standards for machine safety.
Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation.
Auxiliary contact blocks (sold separately) allow you to control more components, such as signaling devices or basic relays.

Solid State DIN-Rail Mount Multifunction Interface Timer Relays

Considered solid state because they don’t have any moving parts, these timer relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, preventing damage to your components from voltage spikes, amplifying the relay's signal, and reducing signal interference. Use these relays with switching applications, such as small motors and pilot lights. They offer multiple timing functions in one relay. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relays disconnect from the socket for easy replacement.
