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 Modbus RTU communication bus. It can be used with other systems where the communication is consistent with the Modbus RTU standard. Power consumption : 9.5 mA in standby; 70 mA while signalling; up to 60 mA when signalling switched off Protection class : IP 65 (case) Operating temperature : -40°C ÷ +85°C Power supply : typ. 10V DC (9V DC ÷ 12V DC) Communication interface : RS-485 / Modbus RTU Storage temperatur e: -40°C ÷ +85°C Case dimensions : 64 x 58 x 90 mm Number of modules in 1 network : max. 127 Connection cable : 4 conductors (2 supply conductors + 2 data transmission conductors) Mounting : to wall, 2 M3 bolts Transmission parameters : 9600 bit/sec
