ELECTRICAL CONNECTIONS

CAUTION

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…).

ANALOG INPUTS : The device has 8 analog inputs that can be configured via DIP-SWITCH:

SETTING THE DIP-SWITCHES

WARNING
The DIP-switch settings are read only at boot time. At each change, perform a restart. For use and settings via DIP-SWITCH, see the user manual available on the website on the web page dedicated to the product.

DIP-SWITCH SW2 AND SW3 : ANALOG INPUT CONFIGURATION

• DIP-SWITCHES SW2 and SW3 are located on the back of the device.

SW1 DIP-SWITCH: DEFAULT SETTINGS

SW1

DIP1| OFF| DEFAULT SETTINGS
DIP2| OFF

• DIP-SWITCH SW1 is located on the front of the device.

INSTALLATION MANUAL

CAUTION
The input for the RTD thermoresistance is available only for the first channel. For channels 2 to 8 it is not available.

WARNING
The product is not suitable for connection to a dangerous voltage conductor. The maximum allowable voltage is 50 Vac / 75 Vdc concerning earth.

THERMORESISTANCE

• The SW1 Dip-Switch selector 1 goes to the OFF position. Function valid only for analog input 1.

INSTRUCTIONS FOR ANALOG INPUTS
The analog inputs of this device are designed to measure voltages/currents on floating circuits that is not electrically connected. 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.

DAISY-CHAIN ETHERNET CONNECTION

WARNING
FUNCTION VALID ONLY FOR THE R-8AI/8DIDO-2 AND R-8AI-8DIDO-2-P MODELS

CAUTION
IT IS NOT ALLOWED TO CREATE LOOPS WITH ETHERNET CABLES 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.

FACTORY IP ADDRESS (ONLY R-8AI-8DIDO)

• The default module IP address is static: 192. 168. 90. 101

WEB SERVER

To access the maintenance Web Server, use the following credentials:

• Default user: admin
• Default password: admin

CAUTION
DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.
