X96-2008PL
X96-2008PL is the Digital Input/Output Module. The module provides a total of 16 bits of digital I/O and
wetting/encoder power.
8 isolated digital inputs are provided. These inputs can be configured for use as:
• dry
5
or live
6
contact monitoring,
• quadrature encoder
7
, or
• pulse counter.
4 relay (2 Amp capacity) output points are provided. Form “C” outputs are brought out to the connector
(three connections per relay).
4 isolated open collector output points are provided. These outputs are capable of switching 4.5 to 30 Volts
(externally supplied) at a maximum of 50 ma.
24 volts DC is provided for use as a wetting voltage when needed.
An isolated 15-volt DC power supply capable of providing 200 mA is also provided. The primary use of this
power supply is to power a quadrature encoder. However, it can be used for other purposes if it is not
required for this purpose.
X96-2009PL1
X96-2009PL is the Scintillation Detector Interface Module. This optional
8
module provides:
• 1 isolated scintillation input (pulse counter, max signal 0-12
9
V, threshold 0.6 V)
• 1 head temperature input (1 uA per deg K)
• 1 non-isolated RTD (3-wire) input
• isolated power for the scintillation detector 24 V 40 mA supply
10
.
5
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.
6
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.
7
The interface to the quadrature encoder shall consist of two inputs, 15 volts DC at 200 mA (described in a later section), and
common.
8
At least one detector interface module is required.
9
8.6 V nominal.
10
The power supply has the ability to control the power to the scintillation detector:
• when commanded by the CPU module,
• when the processor on the module detects a condition that could harm the scintillation detector,
• when the watchdog timer generates a reset.
