Bridgetek Modbus Sensors & Actuators

Bridgetek Modbus Sensors and Actuators are a flexible range of industrial and commercial devices designed for seamless integration into Modbus RTU networks. The components support a wide variety of applications, including building management systems, smart homes, industrial controllers, computers, and wireless Modbus bridges. Using cost‑effective RS485 cabling, devices can be daisy‑chained over long distances while carrying both power and data, making it easy to build scalable and efficient Modbus installations.

This Bridgetek portfolio includes compact multi‑sensors, sensor adapters, and actuator controllers. The sensors measure parameters such as temperature, humidity, air quality, and fluid properties, while actuators control equipment such as fans, motors, pumps, and lighting. Output options include mechanical and solid‑state relays, digital/analog outputs, and dimmers. These devices can be freely mixed on the same Modbus bus and used alongside third‑party Modbus RTU products, supporting networks of up to 32 devices, or up to 247 with repeaters, depending on the host.

Designed for ease of installation and configuration, Bridgetek Modbus devices feature terminal‑block connectivity and include RS485 adapter cables and status LEDs for quick identification. Configuration is performed through the Bridgetek Modbus Configuration Utility, allowing fast setup, testing, calibration, and firmware updates without DIP switches or jumpers. With low power consumption, high reporting rates, and multiple mounting options (including flush, swivel, and DIN‑rail), these devices offer a robust, scalable, and visually unobtrusive solution for modern Modbus sensing and control systems.

Features

  • Compatibility - mix and match sensors and actuators in any order on the bus
  • Long distance - up to 1200m, depending on cabling
  • Scalable - connect up to 32 devices per bus and up to 247 with repeaters (maximum depends on Modbus host)
  • Simple installation - daisy chain devices with cost-effective CAT5e cabling for power and data
  • Shipped with a corresponding 300mm RS485 Modbus adapter cable to convert the onboard JST or RJ11/12 connector to a 5-way terminal block
  • Supports a wide range of applications with different sensing and control requirements
  • Flexible mounting options, including flush, swivel, and DIN Rail (options depend on model)
  • Convenient connectivity to the Modbus via a screw terminal adapter
  • Status LED for at-a-glance status information and identification of each device
  • Rapid configuration via RS485 with no DIP switches or jumpers
  • Simple step-by-step calibration via the Modbus Configuration Utility (Zip)
  • High reporting rate for frequent measurements
  • Energy efficient with low power consumption
