    Product Description

    HT1004 4 Channel Relay Interface Card (RS232) / Electronics Kit


    The HT1004 is a 4 channels relay interface card which designed to be connected to any RS232 compatible serial port and commanded via a simple command protocol. User are required to write a custom applications in any programming language (LabView, Visual Basic, Visual C, C++,) on any platform (Windows XP/Vista/7and 8) to send the specified hex code to control the relay output. Each output can be independently set under software control. It can be used as a standalone card also, addressed by Tact Switch. 



    • Input Voltage: 12VDC or 12VAC 
    • Used IC 89C2051
    • Standard RS232 Connection
    • RS232 Input to drive the card with computer or terminal emulation program (such as windows hyperterminal, , baud rate: 9600)
    • Reverse Polarity Protection
    • LED Indicator for Relay On
    • With 4 Channels Relay Output
    • Command (hex code) for Relay1:H31 ; Relay2:H32 ; Relay3:H33  ; Relay4: H34
    • Build in Full Wave Rectifier Circuit which allowed to power the board by Transformer (12, 0, 12 1A)


    Assembly Instructions

    • Check off the components in the package against the component listing before assembly.
    • Start with the smallest components working up to the taller components, soldering any interconnection wires last.
    • Place and Solder the components into the board, make sure the components are in right position according to the overlay of PCB


    Test & Adjustment

    • After assembled, please check & ensure the value & polarity for all components were inserted into PCB correctly, wrong polarity connection of capacitors can caused explosion of failure.
    • Next, ensure all these leads are soldered, no solder bridges between adjacent pads and no dry joint.
    • Once confirmed, connect the power source to the circuit board.
    • If all goes well, this kit starts function as following:
    • For Standalone Card, press a tact switch once to activate the relay and press again to deactivate it. 
    • For RS232 Serial Interface, select the right com port and baud rate, send the command, ex. H31 to turn the Relay1 on, send it again to turn the relay1 off.  



    • Package includes schematic, printed circuit board, head sink and components except the transformer
    • You need to have a soldering skill and basic knowledge of testing
    • For any inquiry or other technical problem, please contact us through sales@hitectrons.com or 07-3344473
