Inputs and Outputs
The CBX-8R8(-H),
FLX-8R8
FLX-8R8-H
and
a set of 8 Universal Inputs and a set of 8 UniPuts
FLX-4R4
FLX-4R4-H
and
have 4 Universal Inputs and 4 UniPuts
FLX-16DI
has 16 Digital Inputs only.
Any of the terminals can be configured as inputs. Any of the UniPut™ terminals
can be configured as an output.
Input modes
Universal Input terminals and UniPut™ terminals can be configured as inputs in
almost identical fashion:

Resistance Input mode (Passive Input)
Passive Inputs are all those devices that vary in resistance, including switch
contacts. These all require a current supplied by the
this resistance can be measured.
The passive sensor types supported by the
•
Pre-programmed Passive Temperature Sensors.
•
Potentiometer (normally used as a 0 to 10 KΩ or a 1 KΩ to 11 KΩ variable
resistor to give a 0 to 100 % output).
•
Volt-Free Digital Input (the controller strategy measures the contact resistance
and gives a 0 or 1 output).
•
Straightforward Resistance measurement. This can be used with the
block to give a temperature output for temperature sensors that are not
Linear
factory pre-programmed into the CBX-8R8(-H).

simply select '

parameters (the Pulsed option increases accuracy by
in the
Pulsed
Advanced
eliminating any self-heating in the passive temperature sensor, while the
Continuous option can trade absolute accuracy for speed).
In Passive Input Mode the Uniputs™ and Universal Inputs configure like this:
Note: The reference voltage can be pulsed or continuous, using the solid state
switch.
A pulsed reference gives optimum accuracy by eliminating self-heating in
the sensor, and this is the default setting.

UniPut
24 V AC Detection
If 24 V AC is connected to a Uniput™ terminal, then the 24 V AC Detect circuit will
detect this and will open switch SW1. SW1 stays open for the duration of the 24 V
AC state. When 24 V AC is removed from the Uniput™ terminal then the short
circuit or open circuit states can again be detected.
Voltage input mode (Active Input)
Note: Input Impedance for Universal Input terminals is 130 kΩ.
Input Impedance for Uniput™ terminals is 40 kΩ.
The 0 ... 10 V input is used for Active analog and binary measurements. 'Active'
means that there is no current supplied by the
signal is generated completely by the Sensor.
The 'mV' sensor setting gives a value between 0 and 10,000, which represents
voltage in mV.
In 0 ... 10V Input Mode, the Uniputs™ configure like this:
