Electronic safety relays
with soid state output C67xx
Electronic safety relays with solid-state output C 67xx
• Solid-state outputs – no contacts – no wear
• Low weight & small size – Space and weight advantage
• Positively guided standard contactors operate as switching elements
C 67xx safety relays are solely used to monitor the sensors connected (e.g. limit switches resp. EMERGENCY-STOPbuttons) and actuators (positively guided standard contactors).
The basic unit C 6700 itself does not feature safe outputs. Only when the unit is used together with positively guided
actuators (e.g. contactors B6, B7) the complete circuit fulfi lls up to category 3 to EN 954-1.
Us = 24VDC; Ue = 24VDC; Ie = 0.5ADC 13.
The safety relay C 6701 with solid-state outputs can be used directly to switch off connected devices up to category 3 or 4 to
EN 954-1. Us = 24VDC; Ue = 24VDC; Ie = 1.5ADC 13.
The safety relay C 6702 with solid-state outputs can also be used to directly switch off connected devices up to category 3 to
EN 954-1 and stop categories 0 and 1 at a width of 22.5 mm only.
Time delay settable from 0.05-3 or 0.5-30s. Us = 24VDC; Ue = 24VDC; Ie = 1.5ADC 13.
