Honeywell SmartLine Wireless Universal I/O - STUW750/ STUW751

The SmartLine Wireless Universal I/O Transmitters allow seamless wireless integration of high-level analog signals, thermocouples, milli-volt levels, and discrete contact closures directly into control systems.

SmartLine Wireless Universal I/O Transmitters are available in two models:

• STUW750 - Supports a total of three inputs which can be a combination of 1-3 high level analogue inputs (0-20 mA/4- 20 mA) or 1-3 thermocouple, milli-volt or discrete inputs.
• STUW751 - Supports two inputs, which can be a combination of 1-2 high level analogue inputs (0-20 mA/4-20 mA), 1-2 thermocouple inputs, 1-2 milli-volt inputs or 1-2 discrete inputs and one discrete output that can be used to trigger an alarm or turn on/off a device. 

How it works?

Honeywell’s Universal I/O Transmitters transform measurement data into wireless signals that can be sent to another transmitter, field router, or access point, which then forwards the information to a gateway. These nodes communicate wirelessly with each other, creating a managed, secure, and redundant network.

Honeywell’s gateway (Wireless Device Manager) facilitates the transfer of data into various control systems through widely used interfaces such as OPC client, HART, or Modbus/TCP. Its integration with Experion® PKS and other control platforms ensures precise local measurements at the system level without the common errors introduced by traditional A/D and D/A converters.

The SmartLine Wireless Universal I/O Transmitters are fully compliant with the international ISA100 wireless standard.

Problem Solving

Combining multiple input types with a discrete output in one device lowers installation and configuration expenses compared to using several single-function units. Additionally, Honeywell’s Universal I/O Transmitters offer increased flexibility for monitoring applications located in remote, hard-to-access areas or without power, and for setups needing frequent reconfiguration.
