Application

SLATE™ brings configurable safety and programmable logic
together into one single platform. The platform can easily be
customized for almost any requirement or application–offering
virtually limitless development opportunities with far less
complexity.

The R8001L8001 SLATE Limit Control Module is part of the
SLATE Combustions System. The SLATE Limit Control Module
provides the ability to bring in any type of analog signal and
create limits on either pressure or temperature without needing a
UDC Controller.

Features

• 12 limit blocks with each block monitoring any sensor or pair
of sensors

• One limit module for multiple burner controls

• 4 sensors available for Limit Block use (2 sets of redundant
safety inputs)

• Unused Analog Cells available for general purpose I/O
configuration

• Redundant limit relay output

LED Array

There are four LEDs on the front of the Limit Control Module
that provides quick identification of the system status and any
problems that might occur. The status is broadcast to other
modules on the platform bus in case they are affected by the
inoperable modules.

The LEDs on the module are for the sensors, the inputs and
outputs, and for the Reference V.

Terminals 18 and 19 are the limit contacts.

Terminals 20 and 22 are reference voltage terminals to indicate to
the Limit Module what reference voltage it’s operating at.
