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.
