Notes: "COMMON" can be connected either to "+5 V SUPPLY" or to an external
power supply (max. +15 V
between "Switch XXX" and "GND". The Switch inputs are opto-coupler
inputs with an internal 1 kΩ current limiting resistor each.
The "Lamp XXX" outputs are open-collector outputs; small loads, such as
LEDs, opto-couplers, or relays, can be driven directly. The current must
not exceed 100 mA per output.
The "+5 V" supply current for LEDs or relays must not exceed 50 mA in
total.
