Learn More About Serial Remote I/O Modules

Serial remote I/O is often the better fit when the installation already uses serial comms, when you need to interface with legacy equipment, or when a simple point-to-point or bus-based connection is more appropriate than adding Ethernet infrastructure. Our range is built around RS-232, RS-422 and RS-485 connectivity, which makes it well suited to those kinds of industrial environments.

That depends on the devices you need to connect and the way the system is laid out. RS-232 is often used for more direct device connections, while RS-485 is commonly chosen in industrial control systems and is widely represented across our range. RS-422 can also be useful where serial communication is needed in a more robust industrial setup.

Isolation is often worth considering in industrial environments where electrical noise, grounding differences or connected field devices could affect reliability. Our range includes isolated digital input and I/O options, which can help support more dependable operation in harsher installations.

Yes. We can help you identify the right serial remote I/O solution based on the interface, signal type and installation requirements involved. Whether you need Modbus RTU I/O, temperature inputs, relay outputs, TTL connectivity or a mixed-signal setup, our team can help you narrow down the right fit.
