INSTALLATION REGULATIONS

The module has been designed for vertical installation on a DIN 46277 rail. For optimal operation and long life, adequate ventilation must be provided. Avoid positioning ducting or other objects that obstruct the ventilation slots. Avoid mounting modules over heat-generating equipment. Installation in the bottom part of the electrical panel is recommended.
CAUTION
These are open type devices intended for installation in a final casing/panel that offers mechanical protection and protection against the spread of fire.

ModBUS CONNECTION RULES

1. Install the modules in the DIN rail (120 max)
2. Connect the remote modules using cables of an appropriate length. The following table shows cable length data:
   • Bus length: maximum length of the Modbus network according to the Baud Rate. This is the length of the cables that connect the two farthest modules
   • Derivation length: maximum length of a derivation 2 m For maximum performance, it is recommended to use special shielded cables, designed specifically for data communication.

CONNECTOR IDC10

Power supply and Modbus interface are available using the Seneca DIN rail bus, via the IDC10 rear connector, or the Z-PC-DINAL-17.5 accessory
Back connector (IDC 10)
The illustration shows the meanings of the various IDC10 connector pins if signals are to be sent via them directly.

USB PORT (Z-4DI-2AI-2DO)

The module is designed to exchange data according to the modes defined by the MODBUS protocol. It has a micro USB connector on the front panel and can be configured using applications and/or software programs.
The USB serial port uses the following communication parameters: 115200,8,N,1.
The USB communication port responds exactly like the serial ports, with the exception of the communication parameters. Check that the device in question is included in the list of products supported by the Easy Setup APP
FACTORY IP ADDRESS
The default module IP address is static: 192.168.90.101

SETTING THE DIP-SWITCHES

WARNING
The DIP-switch settings are read only at boot time. At each change, perform a restart.

SW2 DIP-SWITCH:

Through DIP-SWITCH-SW1 it is possible to set the IP configuration of the device:

ATTENTION
DIP3 and DIP4, on models where they are present, must remain OFF. If set otherwise, the instrument will not operate correctly. RS232/RS485 SETTING:
RS232 or RS485 configuration on terminals 10-11-12 (serial port 2)

WEB SERVER

To access the maintenance Web Server with 192.168.90.101 factory IP address type:
http://192.168.90.101
Default user: admin, Default password: admin.
CAUTION
DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.

ELECTRICAL CONNECTIONS

Attention: the upper power supply limits must not be exceeded, as this might cause serious damage to the module.
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, induction ovens, etc.).

POWER SUPPLY

• The power supply is connected to terminals 2 and 3.
• The supply voltage must be between:
• 11 and 40Vdc (indifferent polarity), or between 19 and 28 Vac.
• The power supply source must be protected from any failures in the module by means of a suitably sized fuse.

ANALOGUE INPUTS

• The module has two analogue inputs that can be configured via software as voltage or current.
• For the configuration software, see the user manual
