Description
BSC-50E Remote Alarming System
The BSC-50E Remote Alarming System is an ultra low power, wireless RTU with data logging and alarming capabilities. The battery-powered RTU incorporates a quad-band GSM/GPRS modem, four digital inputs, two analog inputs, one pulse counter input and multiple excitation options for powering measuring transducers. A Lithium Thionyl battery provides autonomous operation for over 10 years.
Applications include:
- Water Resources Management
- Weather Conditions Monitoring
- Power Grid
- Gas Distribution
- Environmental Monitoring
- Telecom & IT
- Tank Level Measurement
The Infinite Advantage
BSC-50E 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) performs the measurement, data logging and alarm condition detection in continuous operation. A powerful communication processor, switched on and off by the system controller, performs data processing and controls communications through the internal wireless MODEM. The result is up to 50% power saving compared to respective units of the competition while performing the same tasks.
Modes of Operation
Modes of operation include autonomous battery operation and 9 to 24V external power supply operation with an uninterruptible transition to battery operation during a power outage.
Measurements & Data Logging
The digital inputs are scanned in a closed loop by the system controller for detecting an alarm condition. Analog input scaling and alarm limits are user definable. The analog inputs are sampled according to the user-defined sampling rate. Sampling rate and sampling duration affect the battery life according to the transducer power supply requirements. Firmware V:7.0 introduces a dual set of sampling, logging, and data transmission rates. The basic set can be superseded by an alternate set on an event. Digital input states, analog input, 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.
Transducer Excitation
The unit provides multiple excitation options for measuring transducers.
Alerting & Messaging
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-50E can be remotely reconfigured by sending configuration commands via SMS to the unit during the periodical status message processing.
