774-300 PNOZ/X1/24V

E-STOP relays up to Category 2, EN 954-1 PNOZ X1 Safety relay for monitoring E-STOP pushbuttons. Unit features Safety features ` Positive-guided relay outputs: – 3 safety contacts (N/O), instantaneous – 1 auxiliary contact (N/C), instantaneous ` Safe separation of safety contacts 13-14, 23-24, 33-34 from input circuits A1-A2, feedback loop Y1-Y2 and auxiliary contact 41-42. ` Connection options for: – E-STOP pushbutton – Reset button ` LED indicator for: – Switch status channel 1/2 – Supply voltage The relay meets the following safety requirements: ` The circuit is redundant with built-in self-monitoring. ` The safety function remains effective in the case of a component failure. ` The correct opening and closing of the safety function relays is tested automatically in each on-off cycle. Approvals Unit description PNOZ X1 The safety relay meets the requirements of EN 60204-1 and IEC 602041 and may be used in applications with ` E-STOP pushbuttons The safety relay is not suitable for noncontact barriers because ` a dynamic start is not possible ` the unit can be started during the delay-on de-energisation time. ‹ ‹ ‹ Block diagram * Safe separation in accordance with EN 60947-1, 6 kV (see unit features) A1 A2 ~ = * Y1 Y2 Input 13 23 33 41 Reset/ Start K1 Power K2 14 24 34 42 Pilz GmbH & Co.
