Installation Regulations

The module is designed for vertical installation on a DIN 46277 rail. Ensure adequate ventilation and avoid obstructing ventilation slots. Do not mount over heat-generating equipment. Installation in the bottom part of the electrical panel is recommended.

CAUTION: These are open-type devices requiring installation in a casing/panel for mechanical and fire protection.

ModBUS Connection Rules

1. Install modules on the DIN rail (max 120).
2. Connect remote modules with appropriate cable length.

Cable Length Data:

• Bus length: maximum length of the Modbus network according to Baud Rate.
• Derivation length: maximum length of a derivation (2 m).

For maximum performance, use special shielded cables designed for data communication.

Connector IDC10

Power supply and Modbus interface are available via the Seneca DIN rail bus (IDC10 rear connector) or Z-PC-DINAL-17.5 accessory. The illustration shows the pinout for direct signal routing.

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

The module exchanges data via the MODBUS protocol using a micro USB connector on the front panel. Configuration is done via applications/software. The USB serial port parameters are: 115200, 8, N, 1. The USB port behaves like serial ports, except for communication parameters. Visit page 1 for more information.

Configuration Options:

• Android APP configuration (CU-A-MICROO TG)
• PC software configuration (CU-A-MICROB)

Check product compatibility with the Easy Setup APP.

To meet electromagnetic immunity requirements:

• Use shielded signal cables.
• Connect the shield to an instrumentation earth system.
• Separate shielded cables from power installation cables.

Power Supply
