The IEC 62591 Interface consists of two parts: the Smart Wireless Field
Link that provides the radio link to the
Wireless
HART field devices,
and the IEC 62591 Interface Module that installs into the ROC800.
Installation and
Configuration
The IEC 62591 Interface module connects to the Smart Wireless Field
Link through a four-wire connection. This allows the Smart Wireless
Field Link to be strategically placed away from the controller in the
optimal location for best network performance. The module provides
12 Vdc loop-output to power the Smart Wireless Field Link.
You can install one IEC 62591 Interface module in any slot on a
ROC800. Modules can be easily installed or removed from the module
slots at any time by removing the two captive screws accessible from
the front of the unit.
IEC 62591 Interface modules are hot-swappable, meaning the module
can be removed and another module of the same kind can be installed.
IEC 62591 Interface modules are hot-pluggable, meaning they may be
installed directly into unused module slots under power.
The module has a removable terminal block for convenient wiring and
servicing. The terminal block can accommodate size 24 to 16 American
Wire Gauge (AWG). A USB port is provided on the module to perform
firmware updates and to provide debug information to support
personnel.
