Modbus/RS-485 Isolated Digital Input Board 4 Channels 5/12/24V Input Current Source/Sink 12/24V Power

This board module reads 5-24 V digital voltage signals via Modbus. It can be read easily from PLCs, industrial PCs, and similar host devices.

Product description

Supports Modbus RTU. It can be added to an existing RS-485 bus.
Simple registers make configuration and programming easy.
The power, communication, and measurement sections are isolated, making the board resistant to noisy environments and suitable for a wide range of installation sites.
The free td-modbus command is provided for operation checks and initial setup.
The optional TDAC-DMK mounting kit enables DIN rail mounting.
Designed in Japan. Volume production, customization, and support are available.
