13. Hardware characteristics and configuration
13.1 Overview
13.1.1 Introduction
This chapter provides details on the hardware characteristics for each hardware module, and for each set of terminals.
General characteristics
Some terminal types are common to a number of different hardware modules. To minimise repetition, the general terminal types are
described under
General characteristics
.
INFO
The
General characteristics
descriptions may include references to hardware modules that are not supported by this
controller. The supported hardware modules are listed in the
Data sheet
.
Technical specifications
More information
See the
Data sheet
for detailed technical specifications for the terminals.
Configuring the inputs and outputs
More information
For information on how to configure the inputs and outputs, see the
PICUS manual
if you are using PICUS, and see the
Operator's manual
if you are using the display unit.
Terminal wiring
More information
See the
Installation instructions
for the terminal wiring options.

The frame ground is required by classification societies. Among other things, it makes the equipment more robust, for example
against lightning.
CAUTION
The frame ground is connected to the power supply terminals through transient voltage suppression diodes (commonly
known as transorbs). To protect the frame ground and power supply, no more than 36 V is allowed between the frame
ground and the power supply terminals.
