2-2 SIMATIC 505–2557 Installation and Operation Guide
2.1 Installing and Configuring the Module
The
installation of the SIMA
TIC 505–2557 Sixteen Channel RTD Input
Module involves the following steps:
1.
Planning the installation
2.
Configuring the module
3.
Inserting the module into the I/O base
4. W
iring the module input connector
5.
Checking module operation
The steps listed above are explained in detail in the following pages.
Planning is the first step in the installation of the module. This involves
calculating the I/O base power budget and routing the input signal wiring to
minimize noise. The following sections discuss these important
considerations.
The SIMA
TIC 505–2557 requires 5 watts of +5 VDC power from the I/O
base. Use this figure to verify that the base power supply capacity is not
exceeded.
Open the shipping carton and remove the special anti–static bag which
contains the module.
!CAUTION
Handling
Static Sensitive Devices
The components on the SIMA
TIC 505–2557 module printed circuit card can be
damaged by static electricity discharge. T
o prevent this damage, the module is
shipped in a special anti–static bag. T
ake the following precautions before re
-
moving the module from the bag, when opening the module, and when handling
the printed circuit card during configuration.
Discharge any static potential by holding the module in its anti–static bag and
touch the metal chassis of the PLC. During the configuration step, hold the
printed circuit card only by its edges. Do not touch the circuit card pin
connectors, or solder connections.
After
discharging any static build–up, remove the module from the static
bag. Do not discard the static bag. You will need it for the following
configuration procedure.
