INPUTS AND OUTPUTS
The CBXi-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™ with relay.
FLX-4R4 and FLX-4R4-H have 4 Universal Inputs and 4 UniPuts 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 measurement
Range: 0 ... 450 kΩ
Accuracy: ±0.5% of measured resistance
Temperature measurement
Range: -40 °C ... +110 °C
Accuracy: 10k NTC sensors (e.g. 10k Type 2 (10K3A1) or 10k Type 3
(10K4A1): ±0.3 °C, -40 to 90 °C (-40°F to 194°F); ±0.4 °C > 90 °C (194°F)
Digital Volt-Free contact, 2 mA contact-wetting current
Pulse counting (volt-free)
up to 20 Hz, 25 ms – 25 ms
Analog Input
Range: 0 ... 10 V
@ 130 kΩ
Accuracy: ±0.5% full
scale [50mV]
Analog Input
Range: 0 ... 10 V
@ 40 kΩ
Accuracy: ±0.5% full
scale [50mV]
Pulse counting (0 … 10 V) up to 20 Hz, 25 ms – 25 ms
Current input
Range: 0 ... 20 mA
@ 390 Ω
Accuracy: ±0.5% full
scale [100μA]
Current input
Range: 0 ... 20 mA
@ 390 Ω
Note: Current Input requires
user-supplied external 390
Ω resistance.
Accuracy: depends
on user supplied
external resistor
Note: Inputs use on-board 16-bit analog to digital convertor.
Note: All inputs and outputs are protected against short circuit, as well as over-voltage up to 24 V AC.
