Power Supply and 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 for Z-TWS4,
Z-PC-DINAL2-52.5-17 for Z-PASS2-S . The following picture shows the
meaning of the IDC10 connector pins.
Power supply is available only from the rear connector for Z-TWS4, while:
Z-TWS4-IO can be powered also through 17-18 screw terminals;
Z-PASS2-S/ZPASS2-S-R01/ZPASS2-S-IO can be powered also through 14-15 screw terminals.
If Z-PC-DINAL1-35 or Z-PC-DINAL2-52.5-17 accessory is used, the power supply signals and communication signals may
be provided by the terminals block into the DIN rail support. In the following figure the meaning and the position of
the terminal blocks are shown. The DIP-switch that sets the 120 Ω terminator is used only for CAN communication (Z-
TWS4 only).
GNDSHLD: shield to protect the connection cables against interference (recommended).
The Device has two RS 485 serial ports for Modbus communication: COM 4 and COM 2. The RS485 connection for
COM 2 can be set up by means of the corresponding screw terminals or by the IDC10 connector. On Z-TWS4, to select
RS 485 on IDC10 connector, put the SW1 DIP-switch on OFF position; on Z-PASS2-S, no operation is needed.
