X96CPUDH
X96CPUDH is a CPU Module that comes preloaded with the HART Level Gage firmware.
X96-2002PL
X96-2002PL is the local Graphics L.C.D. Module. This optional module provides:
• Graphic LCD
• Keypad
X96-2003PL
X96-2003PL is the Ionization Chamber Interface Module. This optional
7
module provides:
• 1 ionization detector input
• 1 feedback input for ionization detector
• 1 head temperature input
• 1 non-isolated RTD (3-wire) input (stuffing option)
• Power
8
for the ionization detector (15 volts at 35 ma and –15 volts at 5 ma).
X96-2004PL
X96-2004PL is the 2-Channel Analog Output Module. This optional module has two isolated analog outputs each of which can be
independently configured as a:
• 4-20 mA current loop,
• a source of 0 to 10 volts, or
• a sink of 0 to 20 ma.
X96-2007PL
X96-2007PL is the HART Daughter Module. This module provides both a 4-20 mA current loop and a HART slave interface.
X96-2008PL
X96-2008PL is the Digital Input/Output Module. A total of 16 bits of digital I/O and wetting/encoder power is provided by the
module.
8 isolated digital inputs are provided. These inputs can be configured for use as:
• dry

or live

contact monitoring,
7
At least one detector interface module is required.
8
The power supply has the ability to control power to the ionization detector:
• when commanded by the CPU module,
• when the processor on the module detects a condition that could harm the ionization detector,
• when the watchdog timer generates a reset.
9
When used with dry contacts, jumpers shall be used on the connector block to provide the wetting voltage. When used in this
mode, input to input isolation is not maintained.
10
When used with live contacts, each input shall be able to accept up to 30 volts DC. Zero volts to 0.8 volts are recognized as a
logic zero and 2.5 volts to 20 volts are recognized as logic one.
