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.

The product is not suitable for connection to a dangerous voltage conductor. The maximum allowable voltage is 50 Vac.

THERMORESISTANCE

The relative dip-switch goes to the OFF position. Function valid only for analogue input 1.

INSTRUCTIONS FOR ANALOGUE INPUTS

The analogue inputs of this device are designed to measure voltages/currents on floating circuits that is not electrically connected to each other. It is also possible to measure
currents/voltages on non-floating circuits, with a potential difference between negative terminals not exceeding 200 mV. 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 wir  the thermocouples on an isothermal terminal board separate from the device.Input No. 1 set as Pt100 will then be used to measure the cold junction temperature of said terminal block.

DAISY CHAIN ETHERNET CONNECTION

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

WEB SERVER
To access the maintenance Web Server with the 192.168.90.101 factory IP address Default user: admin; Default password: admin http://192.168.90.101

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