WIRELESS DIGITAL I/O MODULE

Add Discrete I/O Points to Any OTC Sensor Network

WIRELESS DIO

HIGHLIGHTS

  • 6x programmable digital I/O channels
  • Supports any mix of inputs and outputs
  • Normally open/close, counts, pulsed modes
  • 10 ms to 2000 ms debounce filter
  • 1 Amp sink current for open-drain outputs
  • -40 °C to 80 °C
  • Class I, Division 2 (Zone 2)
  • 900 MHz / 2.4 GHz / 868 MHz
  • Secure AES encryption

Scalable I/O Solution

The OleumTech® Wireless Digital I/O Module provides a quick and scalable solution for adding up to six digital I/O points to any OTC Sensor and I/O Network. Each of the digital channel can be programmed independently as inputs or outputs. Each of the channels can be setup as input, counter, output, or pulsed output. The Wireless Digital I/O Module communicates with an assigned wireless gateway in the network. This wireless device is certified for use in Class I, Division 2 (Zone 2) hazardous locations.

Robust Range, Advanced Networking

With the provided robust RF range, the Wireless Digital I/O Module can rescue stranded I/O points that was once economically not feasible. The Digital 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.
