screw terminals. Ribbon cable to screw terminal adapters are also available from a number of different
sources.
Any eight digital devices or one eight-bit analog device can be connected to any ‘ " J6 ’ cable as shown.
The LED between the ground (pin #1 brown) wire and supply (pin #10 black) wire acts as an indicator that
is lit if the fuse for that channel is OK.
All outputs are open collector switches to ground. Each output is individually protected from over cur-
rent conditions and transient spikes. Flyback diodes are included in the outputs for driving inductive loads.
Larger inductive loads may require flyback diodes be installed directly across the loads. Power is supplied
through a diode and a solid state circuit breaker to the common pin(s) on the connector. A safe level of cur-
rent is 150 milliamperes simultaneously on each output. This is sufficient to drive most small relays, valves
and other similar loads directly. If fewer than eight outputs are on at one time, then the outputs are rated as
shown in the following chart.

The supply line for each " J6 is ‘Polyswitch fused’ for one amp. You should treat each " J6 as an indi-
vidual, and not cross the outputs or supply lines from one channel to the lines from any other channel. Do-
ing this won’t cause any damage, but can reduce the protection for the outputs that the fuses normally pro-
vide.
The current Output Capacity of each output is as shown in the following chart:
