`A new industrial standard in remote I/O systems for PLC applications’ that’s how HAWCO describes its RIO modules, from Schleicher. The company claims they’re suitable for most bus systems, including InterBus S, CAN, Profibus DP and Modbus.
They feature on-board diagnostics, and can be used to extend existing PLC applications at minimal cost. Facilities include I/O forcing and indication and the on-board memory and display recalls the last 10 events and I/O image memory.
The fieldbus coupler interface module and the digital and analogue I/O modules are linked via sliding connectors, while wiring is via clamp terminals with integral test points. HAWCO says the design enables quick installation and board replacement without rewiring or removing from the DIN rails. Options include 16 digital I/O, or eight digital and four analogue I/O.
