Technical Information
The following figure shows the output circuit sketch. Level outputs are optically
isolated emitter followers with 10 Ohm series resistors, and a 14 mA max drive
current (24 VDC max).
Figure 86 Optically Isolated Output Circuit Sketch
The following figure shows the input circuit sketch. All inputs are optically isolated
3300 Ohm resistive loads in series with the LEDs of the opto-isolators and voltage
level from +5 VDC to +24 VDC. The required pulse inputs are 200 ms minimum
pulse width.
