pins.) Both the 12V and 5V relays will still pull in fine at this slightly reduced
voltage. If the voltage drop is an issue either increase the output voltage supply
or don’t use the LEDs.
3. Insert the resistor network as shown in Figure 1. The orientation of the resistor is important.
There is a black dot on the resistor net; it should go into the square pad hole.
4. Insert the Diodes. Orientation of the Diodes is important. It will short the circuit if put in the
wrong way. The lead that comes out of the side of the diode with a line on it should go in the
square pad hole (face towards the left edge of the board as shown in Figure 1).
5. Insert the capacitor as shown in Figure 1. Orientation is not important.
6. Install the Screw Terminals (if provided) as shown in Figure 1.
7. Insert the relays as shown in Figure 1. All the relays should be placed in their locations at the
same time before soldering. Push the relays down so they are all flat and start soldering the
terminals, checking to make sure the relays stay flat.
8. Insert the high current driver IC. The orientation is important. The chip will be shorted and will
not work if put in wrong. Pin one goes in the square pad hole such that the notch on the chip
is closest to the label on the board. Refer to Figure 1.
9. Attach either 12VDC or 5VDC to the Output Voltage using the polarity shown in Figure 1. Turn
on the power, no sparks or smoke should appear at this time.
10. Attach your TTL lines from a PIC/+5VDC signal to the Input locations. If you want 1 TTL signal
to dive multiple channels, just install jumpers between the inputs.
11. Attach the Ground for the PIC/+5VDC signal to the input voltage Ground location.
12. Send TTL signals (+5V). The LED should light and the Relays will pull in if you are hooked to
channels 1-4. Channels 5-7 will measure ~90% of the output voltage between the grounded
output channel to the +VDC for the output voltage supply.
