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.
IDC10 CONNECTOR
Power supply and Modbus interface are available using the Seneca DIN rail bus, via the IDC10 rear connector, or the
Z-PC-DINAL2-17.5 accessory.

The meaning of the various pins on the IDC10 connector
is shown in the figure if you wish to supply signals directly
via it.
