PRELIMINARY WARNINGS
The word WARNING preceded by the symbol indicates conditions or actions that put the user's safety at
risk. The word ATTENTION preceded by the symbol indicates conditions or actions that might damage the
instrument or the connected equipment.
The warranty shall become null and void in the event of improper use or tampering with the module or devices
supplied by the manufacturer as necessary for its correct operation, and if the instructions contained in this
manual are not followed.
WARNING: The full content of this manual must be read before any operation. The module must only be used by
qualied electricians. Specic documentation is available at:
www.seneca.it/products/ze-4di-2ai-2do - www.seneca.it/products/z-4di-2ai-2do - www.seneca.it/products/ze-2ai
Important: Obstructing ventilation slots with any object is prohibited.
Installing the module next to devices that generate heat is prohibited.
Electrical and electronic waste disposal (applicable in the European Union and other countries with recycling). The
symbol on the product or its packaging shows the product must be surrendered to a collection centre authorized to
recycle electrical and electronic waste.
The module must be repaired and damaged parts replaced by the Manufacturer. The product is sensitive to
electrostatic discharges. Take appropriate measures during any operation.
SETTING THE DIP-SWITCHES
The position of the DIP-switches denes the Modbus communication parameters of the module: Address and Baud Rate
The following table shows the values of the Baud Rate and the Address according to the setting of the DIP-switches:

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 (see Diagram 1).
- Derivation length: maximum length of a derivation 2 m (see Diagram 1).
For maximum performance, it is recommended to use special shielded cables, such as BELDEN 9841.
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.
Insertion in the DIN rail
As shown in gure:
1. Insert the IDC10 rear connector of the module on a free
slot of the DIN rail (the insertion is univocal since the
connectors are polarized).
2. To secure the module to the DIN rail, tighten the two
hooks on the sides of the IDC10 rear connector.

The module is designed to exchange data according to the modes dened by the MODBUS protocol. It has a
micro USB connector and can be congured 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 RS485 or RS232 ports with the exception of the
communication parameters.
EASY SETUP is the software to use for the conguration.

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 (indi󰀨erent 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.
