6. Installing & Wiring the High Speed Ana Sig Processor (Parison) Board
6.1 Introduction
The high speed analog signal processor card can be specified with 1, 2, or 4
channels of control. The number of channels required will depend on the amount
of control needed by the process. Regardless of the number of channels specified,
wiring from one channel to another will be similar (the difference being the type of
sensor used to provide the input). Current or voltage inputs can be used. Outputs
are voltage only and are intended for use with a drive package or amplifier.
6.2 Wiring of All Analog Inputs & Outputs
6.2.1 Input/Output Specifications
The following is a list of specifications that should be observed when installing and
wiring the high speed analog signal processor card. The specifications apply to all
functions of the same type.
Analog Inputs
Input Signal:
±10 Vdc (nominal) or ±20 mA (nominal)(jumper selectable)
Input Impedance:
100kΩ minimum voltage input: 500Ω current input
Input Function:
Accumulator Position, Die Position, or Hydraulic Pressure (user configurable)
Analog Outputs
Output Signal:
±10 Vdc
Output Current:
4.5 mA maximum into a 2.2k ohm load
Input/Output Isolation:
Each Input/Output pair is isolated from all other pairs
DC Discrete Logic Inputs/Outputs
DC Inputs DC Outputs (Requires External Supply)
Input Voltage: Voltage:
-0.6 (minimum) 24 Vdc maximum
to 40 Vdc (maximum) switched voltage
On Voltage: Current:
10 Vdc 20 mA maximum
switched current
Off Voltage:
5 Vdc
Input Current
Less than 10 mA
at 24 Vdc
Note: When counting boards in multi-rack
systems (for switch settings, RLD/screen pro-
gramming) count each control rack separately.
Class 2 Wiring must be separated a minimum of
1/4 inch from any Class 1 conductors.
