4 Channel Analog Converters with ModBus Interface
XCIO4 Series
The XCIO4 devices are analog converters, fully programmable through a PC application and with ModBus communication interface.
There are four different models:
• XCIO4VMB voltage converter
• XCIO4I
• XCIO4
• XCIO4TMB thermocouple converter
Each device has up to four independent channels, it is remotely configurable through the ModBus interface and in alternative with a
uUSB port with no need for additional power supply. The devices are fully programmable by means of CaburLab software application
or directly accessing the ModBus registers by means of a PLC. The on-board microprocessor manages all the peripherals and the
data transfers. High level precision is guaranteed by the 16 bit A/D to make the device suitable for process control, remote control
and building automation applications.

(1) The device is powered by the USB
port when connected through USB.
In this case no communication over
ModBus is enabled. When both
USB and ModBus are connected
the ModBus interface has higher
priority

ACTIVE AND PASSIVE SENSORS
The XCIO4IMB device supports both active and passive sensors
Active
OPEN CIRCUIT LOGIC: The XCIO4RMB model is capable to send an alarm in case one of the wires of the sensor is interrupted. To
disable such alarm it is sufficient to connect a termination impedance on the channel.
When the channel is open the reading on the channel will be as follows: 2KΩ = 3200Ω; 500Ω = 500Ω; PT100/PT1000 = 916°C
