Wireless Control Unit:

Wireless-Central-Unit-SIG2RCV

Description:

The SIG2RCV series wireless local receiver unit provides reliable and highly scalable solution for IoT deployment. The SIG gateway is versatile device which reads the MODBUS memory map of any RS-485 MODBUS protocol device and sends data to the cloud server. The data stored can be viewed as per customer requirement on dashboard. SIG is an ideal solution for online monitoring of RS-485 MODBUS data.

SIG mainly consist of GSM module and microcontroller based control circuit.

SIG supports generic MODBUS RTU, MODBUS TCP/IP and MODBUS over TCP/IP Protocols for data acquisition and uses MQTT protocol to communicate with IT application database on cloud. Multiple slave devices can be configured to SIG. It remotely monitor all industrial sensor data to the cloud server.

They can be placed in the Central Monitoring Room or Security Room for remote supervision of the wirelessly connected detectors, transmitters or indicators.

Application:

Basically, these devices can be used for all those similar applications where the conventional cabled Gas detector systems were being used. But, extensively, these devices are required in areas where use of cables is inconvenient due to proximity i.e. the detectors and the Wireless Central Monitoring Units are placed far away or on different floors or where the detectors are placed in confined hazardous areas. Hence, these devices find theirs usage in most of the applications of the following industries.

  • Refineries & Petrochemical plant including offshore drilling and plant shutdowns
  • Bullet yards or Tank farms
  • Steel mills
  • Pulp & Paper Industry
  • Personal Monitoring
  • Gas Pipelines
  • Incoming Cylinder inspection
  • Emergency response
  • Equipment maintenance
  • Pre-entry check quality control 
  • Process or emission gas analysis
