Description
TeSys D time delay auxiliary contact block, for contactors LC1D, LC1F and control relays CAD. It provides 1NO+1NC contacts rated up to 10A 690V AC, On-delay setting range 1-30s, connection by screw clamp terminals. Clip-on front mounting, it procures high reliability and durability. Multi standards certified (IEC, UL, CSA, CCC, EAC), Green Premium compliant (RoHs/Reach).
Features
- Featuring a high-precision pneumatic timing mechanism, this block allows for an adjustable delay range of 0.1 to 30 seconds upon energizing the contactor. This "On-Delay" functionality is critical for star-delta motor starting or sequenced conveyor activation, preventing massive power grid spikes and mechanical strain by ensuring equipment doesn't all pull high-inrush current simultaneously.
- Engineered for seamless integration, this auxiliary module clips directly onto the front of Schneider Electric TeSys D and TeSys F contactors or control relays. This tool-free, snap-on mounting saves significant installation time and panel space, allowing industrial electricians to add advanced timing logic to an existing motor starter without the need for additional DIN-rail timers or complex rewiring.
- Equipped with one Normally Open (NO) and one Normally Closed (NC) instantaneous contact set, this block provides versatile feedback for your automation logic. You can simultaneously signal a PLC that the timing sequence has begun while interlocking another component for safety, ensuring your control circuit operates with the high reliability required in demanding manufacturing environments.
- Built to withstand millions of mechanical cycles, the LADT2 is designed for the rigors of heavy industrial use. The IP20 finger-safe terminals protect maintenance personnel from accidental contact with live circuits, while the rugged housing ensures consistent timing accuracy even in high-vibration environments, reducing unplanned downtime and long-term maintenance costs.
