44
• quadrature encoder 11 , 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 12 module provides:
• 1 isolated scintillation input (pulse counter, max signal 0-12 13 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 14 .
11 The interface to the quadrature encoder shall consist of two inputs, 15 volts DC at 200 mA (described in a later section), and
common.
12 At least one detector interface module is required.
13 8.6 V nominal.
14 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.
