Power Supplies

One power supply module can provide up to 30 W if the chassis is mounted in a
Zone 2/Class I, Div 2 area and up to 45 W if the chassis is mounted in a safe area.
Note that the power dissipation is approximately 15% of the power consumption.
Based on the module configuration, additional power supply modules may be
added to the 1719-A22 and 1719-A24 chassis to support the power consumption
requirements of all the modules on the chassis. When more than one power
supply module is used, the load is automatically shared between the power supply
modules. Up to three power supply modules can be used on the 1719-A22 or
1719-A24, offering N+1 power supply redundancy.
The Integrated Architecture® Builder includes a power consumption calculator to
support determining how many power supply modules are required. The table
below shows the consumption values of each module at 12V DC:

Field Wiring

The following accessories are available for field wiring.
Terminal Blocks
Terminal blocks are wired to the field devices, attached to the front sockets of the
I/O modules, and tightened using the side screws. Terminal blocks can come in
the form of screw terminals or spring terminals.
