MONNIT Wireless Serial Modbus Gateway

SKU: MNG2-4-SG-SMG
$582.00Price
MONNIT Wireless Serial Modbus Gateway provides a practical interface between Monnit ALTA wireless sensors and wired Modbus systems. It supports RS-232C and RS-485 communications and Modbus RTU/ASCII serial protocols, allowing wireless sensor data to be incorporated into existing control and monitoring infrastructure. The 433 MHz version is specified by Monnit for Australia and Asia-Pacific applications.

The MONNIT Wireless Serial Modbus Gateway acts as a data concentrator for Monnit ALTA wireless sensor networks. It allows wireless sensing devices to communicate with existing serial Modbus infrastructure, including PLC and SCADA systems.

The gateway supports both RS-232C and RS-485 interfaces and communicates using Modbus RTU or ASCII serial protocols. A protocol selector jumper is provided for selecting the RS-232 or RS-485 interface.

How it works

  • ALTA wireless sensors transmit their measurements to the gateway using the Monnit wireless network.
  • The gateway collects the wireless sensor data and makes it available through its serial interface.
  • RS-232C or RS-485 can be used to connect the gateway to compatible Modbus equipment.
  • The gateway can be incorporated into systems using a Modbus master such as a PLC or SCADA system.
  • Monnit specifies support for up to 50 wireless sensing devices per gateway.

Why choose this product

  • Provides a way to add Monnit ALTA wireless sensing to an existing serial Modbus installation.
  • Supports both RS-232C and RS-485, giving system integrators flexibility when connecting to existing equipment.
  • The 433 MHz model is identified by Monnit for the Australia and Asia-Pacific region.
  • Suitable where wireless sensor data needs to be incorporated into established industrial control or monitoring infrastructure.
  • Includes a high-gain antenna and RP-SMA antenna as specified on Monnit's product page.

Benefits

The gateway can help reduce the need to run individual sensor wiring back to a control system by providing a wireless connection between ALTA sensors and the existing Modbus network. Its support for common serial interfaces also makes it suitable for integration with established automation equipment.

The stored message capacity can help retain wireless sensor messages for later communication, while the status LEDs provide visual indication of wireless activity, wired activity and system status.
