Section 2: Introduction
ZOC33/64PxX2
This module contains sixty four (64) pressure sensors in
eight sensor packs. Each sensor pack contains:
•
eight sensors
• a calibration valve
• a duplexing valve
• an excitation board
• a high speed multiplexer
• 16 input tubes (Bank A and Bank B, 8 inputs each)
The sensors are arranged in eight groups of eight. Each
sensor has two pneumatic inputs: Bank A and Bank B. The
inputs are switched pneumatically by enabling the duplex
-
ing valve. Even though there are 128 pressure inputs only
one Bank of 64 pressure inputs can be measured at one
time. Each group of eight sensors may be a different range.
The standard output of the module is ±2.5Vdc correspond
-
ing to the channel selected by a CMOS level 6 bit binary
address.
