ELECTRICAL CONNECTIONS
The upper power supply limits must not be exceeded, as this could cause serious damage to the module.
Switch the module off before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc...).

INSTRUCTIONS FOR ANALOG INPUTS:
The analog inputs of this device are designed to measure
voltages/currents on oating circuits that is not electrically
connected to each other.
In the case of measurement with thermocouples it is
possible to obtain correct measurements even if they are
applied to common metal parts.
The temperature measurement using thermocouples can be
affected by measurement errors due to the determination of
the cold junction temperature carried out near the terminal.
To eliminate any measurement errors it is necessary to wire
the thermocouples on an isothermal terminal board separate
from the device as shown in the diagram on the side.
Input No.1 set as Pt100 (see the DIP- SWITCH table) will
then be used to measure the cold junction temperature of
said terminal block.

FEATURE SUMMARY
THERMORESISTANCE
The SW1 Dip-Switch selector 1 goes to the OFF position.
Function valid only for analog input 1.
The product is not suitable for connection to a dangerous voltage conductor.
The maximum allowable voltage is 50 Vac / 75 Vdc with respect to earth.
WARNING
The input for the RTD thermoresistance is available only for the rst channel. For channels 2 to 8 it is not available.

DAISY-CHAIN ETHERNET CONNECTION
CAUTION
WARNING
IT IS NOT ALLOWED TO CREATE LOOPS WITH ETHERNET CABLES
FUNCTION VALID ONLY FOR THE R-8AI/8DIDO-2 AND R-8AI-8DIDO-2-P MODELS
Using the daisy-chain connection it is not necessary to use switches to connect the devices.
The following examples show the correct connections.
There must be no loops in the Ethernet cabling, otherwise the communication will not work. The modules and switches
must be connected eliminating any loops. The following examples show the incorrect connections.
The LAN fault-bypass function allows you to keep the connection between the two Ethernet ports of the device ON, in the
event of a power failure. If a device turns off, the chain is not interrupted and the devices downstream of the switched-off
one will still be accessible. This function has a limited duration: the connection remains active for a few days, typically 4.
The fault-bypass function requires that the sum of the lengths of the two cables connected to the switched off module is less
than 100m.

ETHERNET CONNECTION RULES
For the Ethernet cabling between the devices, the use of the unshielded CAT5 or CAT5e cable is required.
