CAI8 Module
CAI8 is an open frame CanBus module with CanOpen protocol mountable on a standard DIN rail, which provides 8 analog inputs.
The input mode can be modified by software, allowing the module to read differential voltage inputs with dynamics 0/10 V or +10/-10 V, current signals with dynamics 4/20 mA or 0/20 mA and potentiometers directly powered by a reference voltage source, protected from short circuits.
On CAI8P module all the analog inputs are configured to read only PT100 temperature transducers.
3 groups of spring-cage connectors are provided:
- 2 connectors for module 24 V power supply.
- 32 connectors grouped in 8 independent subgroups of 4 connectors. Each subgroup provides these connections:
- Potentiometers positive reference voltage / Pole PT100.
- Differential voltage input negative pole / Current input negative pole / Pole PT100.
- Differential voltage input positive pole / Current input positive pole / Potentiometer center terminal.
- Potentiometer 0 V reference.
- 6 connectors for the CanBus line (CANH, CANL e GND_CAN input, CANH, CANL e GND_CAN output).
