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,

• quadrature encoder

, 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

module provides:

• 1 isolated scintillation input (pulse counter, max signal 0-12

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

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.

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.

The interface to the quadrature encoder shall consist of two inputs, 15 volts DC at 200 mA (described in a later section), and

common.

At least one detector interface module is required.

8.6 V nominal.

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.
