Code: TRS-B1a
  • sound signal device
  • designed for multipoint temperature and humidity measurement systems
  • RS-485 / Modbus RTU communication
  • possibility of connecting max. 127 modules on the RS-485 line in one network
  • network solutions
  • SimCorder software to support the system

The TRS-B1a sound signal device is designed to signal events with a sound or light. It is controlled by means of RS-485 link, which allows for activating of the sound signal (a buzzer with variable tone) and/or light signal (a flickering diode). The module is dedicated to the TRS Temperature Recording System and it is equipped with RS-485 / Modus RTU communication interface. It can be used with other systems where the communication is consistent with the Modbus RTU standard.
