Features

l PLC controllable electronic switching amplifier (max. 3 A) with additional protective and control functions for DC 24 V loads (e.g. solenoids, magnetic brakes, electromagnetic clutches, monitoring and indicator lamps). l Overload and short-circuit proof double pole switching output with in-rush current and short-circuit limitation. l Electronic disconnection upon - an overload in the load circuit, - short-circuit in the load (load+/load-, load+/-US, and load-/+U S), followed by 2-pole isolation of the load circuit (via relay contacts). l Control input “In/Ctrl” with control current indication (YELLOW LED). l “O.K.” and availability indication (GREEN LED). l Short-circuit and overload indication (fault indication F and RED LED). l “Err1” group fault signalisation – all faults will be signalled: - wire breakage in the load circuit - earth fault at switching output - internal faults - overload or short circuit in the load circuit l “Err2” fault signalisation: - only overload or short circuit in the load circuit - reset required l Integral protection against reverse polarity and overvoltage for the control and load circuit.
