New Product Announcement from AutomationDirect -- White Paper - When to use Multi-Function Safety Relays

AutomationDirect announces the release of a new White Paper, “When to Use Multi-Function Safety Relays” that explains how to determine when applications will benefit from multi-function safety relays over other options.

Many machines and robots require safety circuits to stop all or part of operation in the event of an emergency. Safety circuits are also used to keep all or part of a machine or robot from running while there is human activity in close proximity, either for normal operations or maintenance.

The White Paper describes how one or more multi-function safety relays can often be used to replace many basic single-function safety relays, simplifying installations and saving money. In many cases, multi-function safety relays can be used instead of a safety-rated PLC, resulting in substantial savings while streamlining implementation and maintenance.

This White Paper also explains that machines and robots with just a couple of basic safety inputs, such as an E-stop and one or two door switches or other safety-related inputs, are typically best served by a safety system with one or two single-function safety relays. When a machine has many I/O points, with a high proportion safety-related, a safety-rated PLC is often the best fit. But for a machine or robot in between these two extremes, an easy to configure and inexpensive safety system using multi-function relays may be the preferred choice.
