RXD-101
Decoder for Multi-channel Receiver System
Supply 8 Volts DC, minimum 7 Volts DC, absolute maximum 11 Volts DC.
Current consumption of each decoder is approximately 10mA at 8 Volts DC.
If LED is used on the output, replace wire link with suitable resistor.
Output transistor (BC337) may switch up to 100mA and up to 24VDC.
If switching inductive loads (relays), no diode across relay is necessary to protect output transistor.
For latching on applications install latching diode (IN914), same direction as existing IN914.
To unlatch the 8 Volts supply must be interrupted momentarily.
Above connections are drawn as “View to component side”.
For panel mounting the RXD-101 use a 6-way , 156” edge connector : Elsema part Number : 6W-edge.
Printed Circuit Board dimensions 59 X 39 mm. |

Assembly Circuit For Multi-Channel Receiver

Notes:
Select LED-resistor on RXD-101 card to suit current through LED.
If relay is used in place of LED, bridge out LED resistor.
LED or relay will only be ON if corresponding decoder is ON.
Relay “Z” will be energized if any decoder is ON
When designing power supply, provide 7 mA for FMR-100 and 10mA for each decoder.
Absolute maximum voltage on 8.volt rail is 11 VDC, higher voltage will damage decoder.
Latching and non-latching decoders may be used in one system.
FMR-100 and RXD-101 operates normally on 8VDC (Minimum 7 VDC and maximum 10 VDC)
If latching decoders are used provide N/C reset button in positive supply line.
Absolute maximum input voltage to regulator REG-108 is 40 VDC
Antenna, use 1 to 2 metres straight wire. Install antenna away from metal parts.
For panel mounting the RXD-101 use a 6-way , 156” edge connector : Elsema part Number : 6W-edge
