1 / 2 page 5-12 Prosafe Trapped Key Interlock Switches Solenoid Release Units Description The solenoid release unit is used for electrical isolation of machinery to enable safe access. It consists of a rotary power switch (RPS) and a solenoid. The trapped key can be removed once an external signal is given to its internal solenoid locking mechanism. An indicator light on the SRU indicates when trapped key can be removed; that is, when power is applied to the solenoid. The solenoid signal only needs to be present when key removal is necessary. The solenoid is rated for 100% duty cycle. Power to the solenoid can be removed after the trapped key is removed. Removing the trapped key causes the isolating power switch to change state; the normally open contacts open and the normally closed contacts (if applicable) will close. The trapped key can then be used in the next sequence of the operation. Features • Direct drive operation—positively opens contacts • Integral solenoid monitoring • Key trapped until release signal is applied • IP 65 enclosure or panel mounted versions • LED or NEON “key free” indication • 316L stainless steel construction • 24V DC, 110V AC/DC or 230V AC solenoid options • Weatherproof stainless steel dust cap as standard • UL and CSA approval on switches • Single or multiple key units available (contact factory) • Replaceable code barrel assembly The Prosafe Advantage Stainless steel construction.
