AERINOS® BSC-50D is an ultra low power wireless RTU with data logging and alarming capabilities via SMS. The battery powered RTU incorporates a GSM/GPRS modem, a USB serial port, 4 digital inputs, an internal temperature sensor and 1 digital counter. A Lithium Thionyl battery provides autonomous operation for up to 15 years.

The Infinite advantage

BSC-50D utilizes a dual processor architecture in order to combine extreme low power consumption with advanced processing and communication capabilities. A system controller (ultra low power MCU) is in continuous operation scanning the digital inputs for alarm condition detection. A powerful communication processor, switched on and off by the system controller, performs all data processing and controls communications through the internal wireless MODEM. The result is up to 50% power economy in compare with respective units of the competition, while performing the same tasks.

Modes of operation

Modes of operation include power network independent battery operation and USB powered operation for parameter setup.

Alerting & messaging

The digital inputs are scanned in closed loop by the system controller for detecting an alarm condition. The alarm condition (closed or open external contact) is user definable. Alarm limits, sampling period, logging rate, data send rate are user defineable. The unit features a dual set of sampling, logging and data transmission rates. The basic set can be superseded by an alternate set on event. Digital input states, temperature values and counter values can be used as trigger sources for rate changes. Ultra low power standby mode followed by frequent data recording and transmission can be selected to fit the application needs, while maximizing the battery life. SMS announcements include alert messages and periodical status messages for verifying unit availability. The unit supports discrete alerting for several users. Message texts are user definable.

Setup and Remote Configuration

The unit can be programmed locally through the serial port or remotely via SMS by using simple ASCII configuration commands. The command set features commands for configuring input alarm parameters, scaling parameters and alarm limits, timing parameters and defining user groups. BSC-50D can be remotely reconfigured by sending configuration commands via SMS to the unit during the periodical status message processing.
