1. Controlled Deceleration Emergency Stop
Utilized in high-inertia machinery (such as industrial centrifuges or heavy rollers) where cutting power instantly is hazardous. The 3PST-NO instantaneous contacts signal the variable speed drive to initiate a controlled regenerative deceleration, while the DPST-NO OFF-delayed contacts (set up to 7.5 seconds) cut physical power to the motor once the system has safely reached a complete standstill.
Problem SolvedPrevents mechanical shock damage and eliminates coast-to-stop safety hazards by managing motor power cutoff timing.

2. Safety Gate Access Interlocking with Delay
Deployed in automated manufacturing lines with hazardous enclosures. The safety relay uses its instantaneous contacts to immediately halt robotic motion when an access request is initiated. The safety latch or gate solenoid is controlled via the DPST-NO delayed contacts, preventing the user from physical access until the adjustable delay (0.5 to 7.5s) expires, guaranteeing all internal hazards have ceased moving.
Problem SolvedEliminates dangerous physical override of moving machine parts by delaying protective barrier opening.

3. Robotic Work Cell Power Sequencing
Manages power shutdown sequences in heavy industrial robotic units. Upon receiving an E-stop input, the instantaneous contacts alert the robot controller to execute a graceful pause (preserving coordinate memory and workpiece lock). The OFF-delay safety contacts then disconnect the main power to the servo drives after the configured delay, ensuring safe physical isolation under dual-channel monitoring.
Problem SolvedProtects expensive workpieces from dropping and guards servo drives against abrupt power loss damage.
