We will be performing maintenance on several web store related systems this weekend starting Friday, October 19th, at 9:00 PM ET and ending Sunday, October 21st at 9:00 PM ET. There may be brief outages and some store features may be unavailable periodically during this time. We regret any inconvenience this may cause.
Safety relay modules provide a high level of fail-safe operation for critical processes and protection. These two-hand safety control relays are ideal for operations where two separate pushbuttons are used to verify a safe state, typically on machinery with dangerous closing movements. Single-channel and dual-function (independently selectable) relays are available.
