moduleX: modular remote I/O over Modbus RTU
Add digital and analog I/O to any PLC, HMI or SCADA over RS-485. Start with the I/O you need and add modules as the project grows.
- Works with any controller: Modbus RTU slave over RS-485, 19200 to 115200 bps.
- Scales with the project: up to 16 I/O modules per master, 10 ms refresh.
- Built for the cabinet: 24 Vdc, DIN rail, IP20, modules detected automatically.
How moduleX remote I/O works
One master on the RS-485 bus and the I/O modules you need next to it.
1. Master
Master module
Talks Modbus RTU over RS-485 with your PLC, HMI or SCADA and manages up to 16 I/O modules.
3. Outputs
Output modules
MX-8DO with 8 digital outputs and MX-4AOV with 4 analog outputs.
moduleX packs ready to ship
Each CORE pack includes the master and the I/O modules, ready to mount on the DIN rail.
Mixed
moduleX IOs CORE
8 digital inputs, 8 digital outputs, 4 analog inputs and 4 analog outputs.
Need another mix? Configure your moduleX with the modules you choose.
moduleX: frequently asked questions
Which PLCs can read moduleX?
Any controller that works as a Modbus RTU master over RS-485: Industrial Shields PLCs, third-party PLCs, HMIs and SCADA systems.
How many I/O modules can one master handle?
Up to 16 I/O modules per master, with a refresh time of 10 ms.
Which moduleX pack should I start with?
With a CORE pack: 8 digital I/O, 4 analog I/O or 24 mixed I/O, ready to ship. If you need another mix, configure the modules yourself.
