Block diagram SAFE-ESTOP
Dual channel emergency stop with short circuit and ground fault monitoring (category 4, up to PL e / SIL 3)
Single channel emergency stop with ground fault monitoring (category 1, up to PL c / SIL 1)
Two channel emergency stop with PNP outputs / OSSD outputs with its own short circuit monitoring (category 4, up to PL e / SIL 3)
Connecting to a safety PLC (category 4, up to PL e / SIL 3) (Safe PLC output meets the required safety level and short circuit between PLC output and SAFE-ESTOP can be excluded)
Dual channel emergency stop with ground fault monitoring (category 3, up to PL d / SIL 2) Note: For applications according EN 81-20 a fault exclusion for short circuit between S12 and S14 is required
Monitored manual start with feedback loop. It is monitored that the start button has been opened before the safety switch is closed.
