Scalable I/O Solution

The OleumTech® Wireless Multi-I/O Module provides a quick and scalable solution for adding analog inputs and digital I/O points to any OTC Sensor and I/O Network. The Multi-I/O Module is equipped with four high resolution analog inputs (24-bit ADC). Each input can be independently selected for either 0-10 Vdc or 4-20 mA mode of operation. It also packs four independently configurable digital channels. Each channel can be setup as an input, counter, output, or pulsed output.

Modbus Master Function

The Wireless Multi-I/O Module also features Modbus master functionality, which gives users read and write controls over assets connected over its RS485 Serial port.

Robust Range, Advanced Networking

With the provided robust RF range, the Wireless Multi-I/O Module can rescue stranded I/O points that was once economically not feasible. The Multi-I/O Module can be added to the network as needed and its I/O points can to be mapped to anywhere within the OTC Network creating an efficient, highly advanced system that is yet easy to create and manage. The Wireless Multi-I/O Module communicates with an assigned wireless gateway in the OTC Network. This wireless device is certified for use in Class I, Division 2 (Zone 2) hazardous locations.
