AutomationDirect announces the release of a new White Paper, “Basic Pneumatic Circuits”, which discusses common pneumatic circuits that can be used alone or as building blocks in larger pneumatics ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Courtesy of www.MikeHolt.com. Based on the 2020 NEC. Class 2 circuits are limited to voltage and current values that don’t (usually) present a shock or fire hazard. The power supply for a Class 2 ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

For reliability, designers must create flex circuits that are neither too thick nor bend too much. • Every flex circuit has a neutral-bend axis. • Smaller circuit thickness reduces the risk of damage ...

The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE NO contacts ...
