An overview

1Solid state relay module, three-phase AC motor (2005LSF-TSeries), the internal for the high reliabilityThreeHeavy interlock design. There are three - phase two - controlled (four - way SCR), three - phase three - controlled (five - way SCR).

2Microprocessor intelligent control module,SMTPatch technology, in addition to the outside of the input control is arranged on the end of the hardware and software of the positive and negative interlocking, in the high voltage output end also set positive and negative interlock.

3The high power output module, and also set the interlock when undoARoad control signalARoad SCR should open but not in time to disconnect,BSCR, even if the control signal is not immediately turned on, only to beAAfter the road was completely disconnectedBRoad, and vice versa.

4Module built-in input protection circuit, in the380VacWithout strong access conditions, even if the input control signal will not trigger scr. Only after the completion of the main circuit, the input terminal is officially started to accept control signals.

5The output terminal and the input control end adopt photoelectric isolation, and the internal control silicon is built in every way.RCAbsorption loop, no external connection.

6Module has twoLEDLED display motor rotation direction, and otherwiseLEDPower indication.

7Control voltage12-24VdcWide range, working current25-45mA, other voltage can also be customized. Enter the common anode or common cathode free wiring, control current of about3mA.

8Module has380VUp electric protection circuit, no surge impact, strong anti-interference ability. Controlled siliconDCBCeramic substrate, current specification for15A-90A.

(2) The current level and model of the relay load output terminal are as follows:(All models are three-phase three-control type)

Outline dimension:105*75*35mm

Principle diagram and wiring diagram:

1,The upper end of the module main power input shall be provided with an over current protection circuit breaker.(Air switch), and must be connected to the fast fuse.(RD).The rated current of the circuit breaker and the fuse can be rated at the rated current of the motor.1.2-1.5Times selected, do not have to choose too large.

2Inside the module, each of the controlled silicon is built-in.RCAbsorption circuit and overvoltage protection circuit, no external connection.

3Three - phase two - controlled four - way SCR, of which fifth are directly connected to the wire, when the module off,380VacThe AC power will still be directly connected to the motor, please note.

4Three - phase three - controlled built-in five - controlled silicon, when the module off, you can cut off the output of all modules.

5Control inputAThe road andBRoad, when the two are no input or have input, the module off the main circuit output. When onlyAControl input, the main circuit output asV - W - UPhase sequence. When onlyBControl input, the main circuit output asU - W - VPhase sequence.

Three phase two controlled type (built-in four controlled silicon)

Three-phase three-control type (built-in five-way thyristor)

Positive and negative input controlThe positive and negative side input control anode connection

Note:A,BBetween the positive and negative control terminal and the input end of the power supply is also photoelectric isolation,COMEnd andA-,B-End can be connected or not connected.
