Description
Features
- Engineered specifically for the TeSys Deca product family, this low-signal interface module offers flawless mechanical and electrical pairing with 3-pole contactors from LC1D09 up to LC1D115. It mounts via a coil wiring adapter, providing a clean, integrated footprint that saves valuable DIN rail space without requiring complex custom brackets.
- This electromechanical relay interface is purpose-built to act as a bridge between low-power electronic controllers and high-power industrial control circuits. It accepts a standard 24V DC input signal at a minimal current draw of just 25 mA, allowing your sensitive PLC, I/O module, or embedded micro-controller to safely actuate heavy-duty contactors equipped with 24V to 250V AC coils (B7 to U7 coil codes) without risk of overcurrent damage to the controller.
- Designed with integrated diode protection, this interface amplifier safely clamps harmful transient voltage spikes generated when the contactor coil de-energizes. It also features a guaranteed voltage state 0 threshold below 2.4V and state 1 at 17V, preventing common field issues like ghost voltages or leakage currents from causing accidental contactor latching or output-card burnout.
- Built to demanding global automation benchmarks, this module carries full UL and CSA certifications and conforms to the rigorous IEC 60255-5 dielectric test standard. With an electrical durability rated for up to 10 million cycles under normal electrical loads and a rugged operating temperature range of -25°C to 55°C (-13°F to 131°F), it provides the continuous, uninterrupted service life required for critical industrial processes.
