Has 8 relays, to control lights, fans, robots etc.
Technical
Connects to the 34pin Printer Port. The first 7 relays are controlled by the seven Centronics Data lines, the eight relay is controlled by Centronics Strobe signal.
The relays can be thus controlled by writing an 8bit value to Port EFxxh. Observe that the CPC hardware inverts the strobe bit (so bit7 has opposite meaning as the other bits).
The relays are rated 7A/120VAC, 7A?/24VDC, 5A/240VAC. Each relay has three contacts (common, position 1, and position 2). The relays are driven by an external 7.5V power supply (required since the printer port does not output supply voltages).
