Presence Sensing Safety Devices Safety Edges Safedge™ Controllers Specifications Standards Description The Safedge controllers are designed to operate with the Safedge profiles. The controller continuously monitors the profile for actuation and generates an output signal when the profile is depressed. The Safedge controller provides a low voltage to the profile. When the profile is pressed, the controller detects a change in resistance and turns off its output relays. When pressure is released from the profile, the output relays of the controller return to an on state. The controller has redundant voltage free positively-guided output relays which can be used to interface with a machine control system.

Switching Current/Volt. 10mA/10V The ‘251’ controller comes capable of operating at 24V AC/DC, or 120/230V AC from separate terminals. An internal switch changes the operating voltage from 120V AC to 230V AC. The ‘252’ controller operates at 24V AC/DC. Max. Response Time 13ms Indication LEDs Green = Run Yellow = Open Circuit Red = Stop Impulse Withstand Voltage 2500V An auxiliary output relay is available to provide a signal about the controller’s status. Three LEDs indicate whether the controller is in RUN, STOP or OPEN condition. The controller operates in manual or automatic reset mode.
