Installation Rules
Isolation Diagram Standards
3-Points 1500 V isolationAC The module complies with the
following standards:
EN61000-6-4/2002-10 (electromagnetic emission,
industrial environment).
EN61000-6-2/2006-10 (electromagnetic immunity,
industrial environment).
EN61010-1/2001 (safety).
All circuits must be isolated from the other circuits under
dangerous voltage with double isolation. The power
supply transformer must comply with En60742: “Isolated
transformers and safety transformers”.
The module is designed to be installed in vertical position on a DIN 46277 rail. In order to
ensure optimum performance and the longest working life, the module(s) must be supplied
adequate ventilation and no raceways or other objects that obstruct the ventilation slots.
Never install modules above sources of heat; we recommend installation in the lower part of
the control panel.
Inserting on the DIN rail
As it is illustrated in the next figure:
1) Insert the rear IDC10 connector on a DIN rail free slot (the
inserting is univocal since the connectors are polarized).
2) Tighten the four locks placed at the sides of the rear IDC10
connector to fix the module.

Electrical Connections
POWER SUPPLY AND CAN/MODBUS INTERFACE
Power Supply and CAN/MODBUS interface are available by using the bus for the Seneca
DIN rail, by the rear IDC10 connector or by Z-PC-DINAL1-35 accessory.
Rear Connector (IDC10)
Z-PC-DINAL1-35 Accessory Use
In the figure the meaning of the IDC10
connector pins is showed, in the case
the user decides to provide the signals
directly through it.
In case of Z -PC- DINAL- 1- 35
accessory use, the signals may be
provided by terminal blocks. The
figure shows the meaning of the
terminals and the position of the DIP-
switch (present on each DIN rail
supports listed on Accessories) for
CAN network termination.

connection cables (it is always
recommended).

CAN bus Connection Rules
1) Install the modules on the DIN rail (max 120).
2) Connect the remote modules using cables of proper length. On the table the following
data about the cables length are provided:
-Bus Length: CAN network maximum length as a function of the Baud rate. It is the lenght of
the cables which connect the two bus terminators modules (see Scheme 1).
-Drop Length: maximum length of a drop line (see Scheme 1) as a function of the Baud
Rate.

For the best performances, the use of special shielded cables is recommended (BELDEN
9841 cable for example).
3) Terminate the two ends of the CANbus network by setting to ON the DIP-switch present
on the DIN rail connection supports (see Accessories) where the two ends are inserted.

DIGITAL OUTPUTS
MI001523-E ENGLISH 5/8
Digital Outputs Connections from terminals
The total current entering on power supply terminal must be limited to 12 A with quick-break fuse or
quivalent protection.
Digital Outputs Connections from connectors (module rear side)
Connection suggested to supply 24 V relays. The total current entering on power supply terminal must be
limited to 0.6 A with quick-break fuse or equivalent protection. Max. current for each output: 25 mA.
