Discrete Interface Transmitter

Discrete Interface Transmitter

Our self-contained, self-powered, discrete interface transmitters capture data and wirelessly transmits it to SCADA systems, PLC, DCS, or to the cloud. Each transmitter has a range of up to 3/4 miles and can be combined with a repeater for a range up to 7 miles. Due to the frequency used, these transmitters are ideal for remote or obscured areas as they can dynamically change their signal to ensure communication remains constant.

  • ideal for remote or congested areas
  • wireless transmission interface for discrete signals
  • data logging and integration to the cloud, DCS, SCADA, PLC, etc.


  • self-contained and self-powered wireless discrete interface transmitters
  • signal transmission up to 7 miles with repeaters
  • optional embedded RTD
  • data logging and integration to the cloud, DCS, SCADA, PLC, etc.
  • solar powered options with battery back-up

Remote Monitoring with a Discrete Interface Transmitter

The model IIoT-2040 Discrete Interface Transmitter from IIoT Technology Innovations, Inc. (IIoTTTI) can be configured for discrete single channel operation. This unit includes a 1/2 inch (1.3 cm) MNPT connector that will interface to any dry contact or relay instrument. The operating range is 1.5 miles (2.4 km). The use of IIoTTTI Intelligent Repeaters expands the range to as much as 7 miles (11.3 km).

Advanced Wireless Data Transmission via Frequency Hopping


Frequency hopping provides redundancy to reduce risk of losing a signal to interference or reception because its unique spread spectrum data transmission technique. This minimizes the effects of walls, structures, and terrain of the signal, which means these transmitters work well even in obscured areas. It also allows data to be secure on both the sending and receiving ends of the process.

These “Data Packets” are transmitted via a “Transmit Only” device in a binary format and the packet is then received and processed into our “Receive Only” Device that is integrated in our Serial Data Processing Unit. After, the data is deciphered into something that is meaningful that correlates to our data base, which is preconfigured at the factory with the field instruments.
