BSC-50E

Introduction

BSC-50E 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, three analog inputs, two pulse counters and multiple excitation options for powering measuring transducers. A Lithium Thionyl battery provides autonomous operation for over 10 years.

The Infinite advantage

The BSC-50E incorporates the common flexible form factor (HL, CF3™) Modem modules of Sierra Wireless. BSC-50E models support 4G, 3G, 2G mobile network technology. The 3G version of the RTU includes GNSS capability (GPS & Glonass Sirf V).

Modes of operation

Modes of operation include autonomous battery operation and 9 to 24V external power supply operation with uninterruptible transition to battery operation during power outage.

Measurements & Data Logging

The digital inputs are scanned continuously 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. BSC-50E 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 The basic set can be superseded by an alternate set on event.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, analog input and counter values can be used as trigger sources for rate changes. Ultra low power stand by 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.
