Product Introduction

The LF-D series contactless relay group developed by Langfeng Electric has the characteristics of small size and strong load capacity, which can be used to expand the load capacity of PLC. It can drive inductive loads such as 6-16 diameter solenoid valves and low-power DC motors,Specially suitable for controlling electromagnetic hydraulic valves in hydraulic systems，Perfectly control large currents with weak voltage signals. Contactless relay group LF-DDN05, LF-DAN05

The best match for NPN transistor output type or relay output type PLC output (e.g. Siemens), and the best match for contactless relay group LF-DDP05, LF-DAP05 and PNP transistor output type or relay output type PLC output (e.g. Mitsubishi Omron).

Product Features:

The contactless relay group is entirely produced using surface mount technology and imported components, enhancing its anti-interference performance.

High integration, compact size, compact structure, easy to install, conducive to reducing the size of the control box and lowering costs.

●Integrated wing shaped heat sink, fully resin sealed, vibration resistant, moisture and dust resistant, with a large power margin.

●Completely isolated between input and output, with damaged output terminalsplcNo impact, the input terminal adopts constant current source technology, which can be directly controlled by the computer. The current remains constant and does not change with changes in voltage（10maThe voltage adaptation range of the left and right control terminals is wide and covers a wide range5v，12v，24v.

Modular assembly, selecting the required number of routes to avoid unnecessary waste.

The input and output wiring terminals are arranged on opposite sides for easy wiring, with standard rail installation and easy disassembly.

● Long service life, making equipment maintenance worry free.

●The contactless relay group has a fast response speed, up to 1KHZ.

●Effective level: N-type high level effective, P-type low level effective
