440F-C251D EDGE Guardmaster is supplied by HuaShengBoYe with verified origin and traceable batch information. We quote against your BOM, confirm packaging and date codes, and ship worldwide from Shenzhen.
Functional positioning Continuously output a detection voltage below 12 VDC to the safety edge profile; When the profile is squeezed and the internal conductive layer is short circuited, the controller immediately disconnects the safety contact and stops the machine. Can detect short circuits, open circuits, and external contactor fusion welding, meeting the requirements of EN ISO 13856-2 for pressure-sensitive protection devices. Electrical specifications Power supply: 24V AC/DC universal (terminals A1/A2) Safe output: 1 redundant normally open passive contact (13-14), rated 2 A/250 V AC (AC-15), 2 A/30 V DC (DC-13) Auxiliary output: 1 normally closed passive contact (21-22), only for status indication, cannot be connected to the safety circuit Response time: ≤ 18 ms Terminal: Screw type, maximum 2.5 mm 2 solid wire/1.5 mm 2 multi strand wire security level Compliant with ISO 13849-1 Cat.3/PL d, IEC 61508 SIL 2 Single channel fault enters safe state, B10d=1 × 10 ? times Installation and Reset Installation method: 35mm DIN rail (45mm wide housing) Reset mode: - Automatic reset: MC-MC terminal short circuit, remove compression to automatically restore output - Manual reset: Connect the normally open reset button in series with the MC-MC circuit, which needs to be manually pressed to restart Contactor monitoring: External normally closed auxiliary contacts can be connected in series in the MC-MC circuit to achieve fusion welding detection "
