2. Insert all the resistors as shown in Figure 6. Use an ohm meter or refer to the color banding to
determine the values of the resistors. The orientation of the resistor is not important.
3. Insert the Rectifiers. Orientation of the rectifier is important. It will short the circuit if put in the
wrong way. The lead that comes out of the side of the rectifier with a line on it should go in the
square pad hole.
4. Insert the capacitor as shown in Figure 6. Orientation is not important.
5. Install the Screw Terminals (if provided) as shown in Figure 6.
6. Insert the Relays as shown in Figure 6.
7. 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 6.
8. Attach 5VDC to the board using the polarity shown in Figure 6. Turn on the power, no sparks
or smoke should appear at this time.
9. 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.
10. Attach the Ground for the PIC/+5VDC signal to the input voltage Ground location.
11. Send TTL signals (+5V). The LED should light and the Relays will pull in. The SPDT relay
(Input 2) pulls in the power, the DPDT relay (Input 1) reverses the load. Pulling in only the
DPDT relay will have no effect. The limits must be made up to complete the circuit. Start by
jumpering the limit S1 to S1 and S2 to S2, then as the load is driving remove the jumpers to
determine which one switches which direction. Each switch will only disconnect power in one
direction; the other direction will work until that switch is opened.
