Inputs and Outputs
The CBX-8R8(-H), FLX-8R8 and FLX-8R8-H have identical I/O capabilities – each has
a set of 8 Universal Inputs and a set of 8 UniPuts
TM
with relay.
FLX-4R4 and FLX-4R4-H have 4 Universal Inputs and 4 UniPuts
TM
with relay.
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 CBX-8R8(-H) terminal so that
this resistance can be measured.
The passive sensor types supported by the CBX-8R8(-H) are:
• 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 Make
Linear block to give a temperature output for temperature sensors that are not
factory pre-programmed into the CBX-8R8(-H).
In CXpro
HD
simply select ‘ Resistance ’ sensor type in the Point Module and select
Pulsed in the Advanced parameters (the Pulsed option increases accuracy by
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
TM
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 CBX-8R8(-H) for the sensor, as 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:
