Multiple WIRELESS Dry Contact Wire Replacement

Description

Eliminate EXPENSIVE SCADA radios or EXPENSIVE cable trenching between dry contact sense points and programmable logic controllers or other dry contact reader end-points.

Using the BATTLE HARDENED, TRIED AND TESTED, LORA (LOng RAnge) wireless protocol, now you can eliminate cable runs of up to 8 miles (or 15km). Of course the LORA loves line of site, but this is also a low frequency spread spectrum technology that can penetrate walls easily. Of course any obstacle reduces the range. This isn’t silly “toy band” radio, this is a spread spectrum frequency hopping radio system that can handle demanding environments.

Each WIRELESS dry contact wire replacement consists of a specially matched endpoints: one end sensing 4x dry contacts as a transmitter and the other end a receiver that outputs/reflects/mirrors those 4 dry contact signals so that a larger control system can read them.. These matched endpoints are interconnected by the rock solid LORA wireless technology.

• 4x Dry Contact Wireless Transmitter Unit
  • UP TO 4 contacts can be sensed
  • 5-24V DC inputs
  • Power: 140mA per transmission / 4mA in idle
  • Paired with a Receiver Unit – This allows for MANY WIRES in an installation, but eliminating 4 per Transmitter/Receiver
  • This is the end that connects to up to 4 dry contacts. Ok to connect just one, but you can do 1, 2, 3, or 4.
  • On a periodic basis that is adjustable, (standard is one min) the transmitter checks the sensor and then transmits the the state of the contacts over the LoRA radio
  • Many of these remote transmitters are powered by small solar installations (you can find easily on Amazon, etc.)
• Wireless Receiver Unit
  • Receives the dry contact state (open/closed) from the paired transmitter unit
  • Places/Reflects the measurement as a dry contact output.
  • 5-24V DC inputs
  • Power: 4mA in idle / A 140mA ack/nack transmission will be sent back to the Transmitter
  • Paired with one Transmitter Unit – allows for MANY Replacement WIRES in an installation
  • This is the end that connects to a a dry contact reader/receiver such as a PLC
  • On a period basis determined by the Transmitter Unit, this receiver receives the dry contact states digitally and then updates its dry contact states that are an exact mirror of what the Transmitter Unit detected. Very cool.
  • Generally, this wireless receiver unit will have power on its end as it is close to many devices which dry contact inputs for a control system.
• Both Units
  • ISM Frequency Bands 915MHz (USA)
  • FCC Certified (USA) & IC (Canada) requirements
  • CE marked
  • RoHS compliant
  • DIN Rail Mounts
  • Professionally Molded Case with custom fit electronics
  • This product is built for scale production
• LORA Wireless Key Bullets
  • AES 120 bit encryption
  • Absolutely NO SIM CARDS required.
  • Security uses several magic numbers
  • Uses ISM bands and requires no special licenses
  • Transmission power are carefully maintained within FCC power envelope
  • As of June 2024, over 350 million LoRa Radio based integrated circuits have been deployed worldwide
