Description
Safety Input Profile
6KΩ, 12V DC open circuit, 4V DC run
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.

Monitoring Circuit

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.

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.

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.
