Power Connector; Rear Of Module Features - GE GCG001 Quick Start Manual

1.3. Power Connector

The module requires a user-supplied 24 Vdc (±10%)
power source wired to a removable screw-terminal
block located on the bottom of the module. The
module draws 0.2 A maximum current.

1.4. Rear of Module Features

Two seldom-needed features are accessed from the rear of the module: an SD card slot and
a firmware load pushbutton. These are described in the following paragraphs.
Secure Digital (SD) Card Slot
The SD card slot is designed to support a Secure Digital (SD) non-volatile memory card in
standard capacity format. This optional card has two distinct uses: (1) backup storage of
some key PROFINET configuration data and (2) loading new module firmware.
Backup Storage
For use as configuration back-up storage, a small SD card is inserted and left in place. The
module will detect the card automatically and store on it a small amount of configuration
data. If the GCG001 must be replaced in the event of a failure, remove the SD card from the
failed unit and install it in the replacement prior to mounting. All PROFINET configuration data
will then be transferred to the replacement module.
Note: SD cards larger than 2 GB are not supported for use with with the GCG001. SDHC
and SDXC formats are not supported.
