USER GUIDE

SCC-DO01 Isolated Digital Output 
Module

The SCC-DO01 is a single-channel, optically isolated digital output 
module. The output circuitry consists of a photomos relay and a load 
resistor. You can use the SCC-DO01 with a 5–24 VDC external voltage 
supply to switch external devices such as transistors and solid-state relays.

Conventions

The following conventions are used in this guide:

»

The 

»

 symbol leads you through nested menu items and dialog box options 

to a final action. The sequence 

File»Page Setup»Options

pull down the 

File

 menu, select the 

Page Setup

 item, and select 

Options

 

from the last dialog box.

This icon denotes a caution, which advises you of precautions to take to 
avoid injury, data loss, or a system crash.

 

When this symbol is marked on 

the product, see the 

Read Me First: Safety and Radio-Frequency 

Interference

 document, shipped with the product, for precautions to take.

This icon denotes a note, which alerts you to important information.

When symbol is marked on a product, it denotes a warning advising you to 
take precautions to avoid electrical shock.

When symbol is marked on a product, it denotes a component that may be 
hot. Touching this component may result in bodily injury.

bold

Bold text denotes items that you must select in software, such as menu 
items and dialog box options. Bold text also denotes parameter names.

italic

Italic text denotes variables, emphasis, a cross reference, or an introduction 
to a key concept. This font also denotes text that is a placeholder for a word 
or value that you must supply.
