SCHNEIDER ELECTRIC LADR23

SCHNEIDER ELECTRIC LADR23 is a rugged off-delay auxiliary timing contact block for Schneider TeSys Deca contactors and control relays. The off-delay auxiliary timing contact block is front clip-on mounted, equipped with 1NO +1NC contacts, timing adjustable from 1 to 30 seconds. This off-delay auxiliary timing contact block uses spring terminal wiring and can be directly fitted onto LC1D contactor series for industrial control logic. The off-delay auxiliary timing contact block meets IEC, UL and CE safety standards for factory, HVAC and marine control cabinet applications.

This unit provides power-off delay sequence logic control for automatic control circuits. The power-off delay sequence logic control keeps contact state for preset time after coil de-energization. The power-off delay sequence logic control realizes motor pump and fan time-sequenced stop interlock protection. The power-off delay sequence logic control supervises delay timing and feeds back contact status to PLC control system. The power-off delay sequence logic control prevents equipment damage caused by sudden power cut in refrigeration and auxiliary machinery systems.

This SCHNEIDER spare is an essential industrial timing auxiliary spare for contactor control panel overhaul. The industrial timing auxiliary spare can replace original LADR23 delay blocks directly. The industrial timing auxiliary spare satisfies international electrical safety specifications. The industrial timing auxiliary spare is widely applied in factory automation, HVAC chiller and marine onboard motor control cabinets.

SCHNEIDER LADR23 off-delay timer auxiliary contact block belongs to TeSys Deca series. It is installed on the front of contactor, provides 1~30s adjustable power-off delay function, used for motor sequential stop and safety interlock control, runs reliably under vibration and humid industrial and marine environments.
