Shop time-delay relays for controlling when electrical loads, machinery and automated processes turn on or off. These relays combine switching and timing functions for equipment sequencing, motor control, alarms, lighting and industrial automation applications.
Wallco supplies time-delay relays from established manufacturers in a range of timing functions, adjustment ranges, coil or control voltages, contact configurations and mounting styles. Use the available technical filters to compare products and identify a relay suited to your control sequence.
Time-delay relays control electrical contacts according to a selected timing function and delay period. Common functions include delay on operate, delay on release, interval timing, repeat cycling and one-shot operation.
Important selection factors include timing function, adjustable time range, supply or coil voltage, contact configuration, contact ratings, mounting style, terminal arrangement and reset behavior. The relay should also be selected for the type of load and control sequence used by the equipment.
Products are organized generically so time-delay relays from different manufacturers can be compared within the same category and technical filters.
