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
8
or live
9
contact monitoring,
•
quadrature encoder
10
, 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 to be used 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 but can be used for other purposes if it is not required
for this purpose.
X96-2009PL
X96-2009PL is the Scintiallation Detector Interface Module. This optional
11
module provides:
•
1 isolated scintillation input (pulse counter, max signal 0-12
12
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
13
.
8
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.
9
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.
10
The interface to the quadrature encoder shall consist of two inputs, 15 volts DC at 200 mA (described in
a later section), and common.
11
At least one detector interface module is required.
12
8.6 V nominal.
13
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.
