Din Rail Solid State Relay LCTC 40A DC-to-AC Heat Sink, 0.96in Width

Description

Product Overview

The LCTC Din Rail Solid State Relay is engineered to meet the demanding requirements of modern industrial automation, offering a robust 40 A rating for DC‑to‑AC conversion across a wide voltage range of 3‑32 V DC input to 24‑480 V AC output. Its compact form factor, measuring just 0.964 in (2.45 cm) in width, allows it to fit into tight spaces where traditional electromechanical relays would be impractical. The relay incorporates an integrated heat sink that dissipates thermal energy efficiently, eliminating the need for external cooling components in most applications. Constructed from high‑grade semiconductor materials, the device delivers fast switching times, low on‑state voltage drop, and long operational life without the wear and tear associated with mechanical contacts. The DIN‑rail mounting clips are precision‑engineered for secure attachment within standard distribution boxes, ensuring vibration resistance and ease of service. With a rated current of 40 A, the relay can handle substantial loads, making it suitable for motor control, HVAC systems, lighting, and other high‑power industrial loads.

Usage

Designed for a broad spectrum of industrial and scientific environments, this solid‑state relay excels in applications that demand reliable, silent operation and precise control. It is ideal for integration into PLC‑controlled panels, SCADA systems, and automated manufacturing lines where space constraints and thermal management are critical considerations. The narrow profile enables installation in densely packed control cabinets, while the built‑in heat sink maintains temperature stability even under continuous duty cycles. Users can deploy the relay in HVAC control units to manage compressors and fans, in motor drive circuits to protect against overloads, and in lighting control panels for dimming and switching high‑intensity discharge lamps. The DIN‑rail clips simplify wiring and reduce installation time, allowing technicians to secure the relay quickly and reliably. For applications requiring multiple relays in close proximity, the design supports the addition of auxiliary cooling fans to further enhance heat dissipation without compromising the compact layout.

FAQ

What input voltage range does the relay accept?

The relay accepts a DC input voltage ranging from 3 V to 32 V, making it compatible with most low‑voltage control circuits.

Can the relay be used in high‑temperature environments?

Yes, the built‑in heat sink is designed to dissipate heat effectively, allowing operation in environments up to 85 °C when properly ventilated.

Is additional cooling required when multiple relays are installed together?

While the relay’s heat sink handles typical loads, installing several units in close proximity may benefit from auxiliary fans to maintain optimal temperature.

How does the relay protect against overloads?

The solid‑state design includes internal protection circuitry that limits current flow and prevents damage during overload conditions.
