Open Collector Outputs; Analog Outputs - Eshed Robotec Controller-PC User Manual

Open Collector Outputs

Digital Outputs 5 to 8 include a transistor with an open collector in its final stage. These
outputs must be connected to a load—resistor, solenoid, relay or motor.
When using an inductive load, such as a solenoid or a relay, connect a reversed biased
protection diode across the load.
You may directly connect a SCORPOWER open collector output to a SCORPOWER
digital input.
Maximum voltage allowed: 24V
Maximum current allowed: 0.5A
Never drive a current totaling
more than 1.5 amps through the
open collector outputs.
Never connect voltage from a
power supply directly to any open
collector outputs (terminals 5–8).
The open collector outputs must
always be connected to a load.
Never connect a load to any
voltage exceeding 24VDC.

Analog Outputs

Make sure the power box is switched off before you make any I/O connection.
Analog Outputs 1 and 2 allow you to control a device which operates in accordance with
an input voltage, such as a LED or a motor driver.
The analog outputs have 8-bit resolution and an output voltage of 0-10V.
Maximum current
allowed: 20 mA
The analog outputs are
activated by software
commands.
