Electro Cam PL-1746 Series - Manual (Page 13)

2-3 Installation
Outputs 32 outputs are accessible through the backplane. 6 (of the 32) optically isolated
outputs are provided on the pluggable output header on the front panel for high
speed, real world outputs. The outputs are either all sinking or all sourcing, depend-
ing on the part number ordered. The outputs are over-current protected by standard
fast-acting 2A, 250V, TR5 fuses. They are over-voltage and reverse-voltage pro-
tected by zener diodes.
Note: Both positive and negative terminals must be connected to power supply for
outputs to function.

Inputs 8 dc inputs are provided on the pluggable input header on the front panel: 6 group
inputs, 1 First Cycle Enable input, and 1 Output Enable input. Each input is optically
isolated. The 8 inputs are separated into two groups of four inputs; each group
shares a common terminal. An input’s state is a logic one when current is flowing
through its terminal on the connector, and it’s state is a logic zero when current is not
flowing. The inputs are not fused. To source current to the inputs, wire the group’s
common terminal to the negative terminal of an external power supply. To sink
current from the inputs, wire the group’s common terminal to the positive terminal of
an external power supply.
