RTU Distributed Computer Control Systems In Industrial Automation

GPRS SMS command remote monitoring building energy management RTU

Product Introduction
INST-RTU wireless remote control terminal series products are the high-performance
monitoring and control device which integrates analog signal acquisition, digital signal acquisition,
relay control output and wireless data communication function. Can be directly connected to the
standard sensors output analog signals ,various level signals, dry contacts, pulse signals, etc. Can
be used as the master station of industrial Modbus-RTU protocol to connect the various
instrumentation of Modbus-RTU protocol(customized).It's the best way for the small-scale
process signal to implement wireless monitoring and control. The internal adopts the STM32 series high-performance ARM controller chip from the industry-leading STMicroelectronics company and combines the industrial wireless communication module from Quectel company, RTU has the characteristics of strong stability, high reliability, real-time, and wide application. It is a new generation of remote monitoring and control terminal combine the telemetry, telecontrol, telecommunication,
remote-adjust function with RS232,RS485 communication function.

Power voltage
Can collect the external supply voltage and the internal standby supply
Analog input4 channels;External signal range:0~5V or 4~20mA;Acquisition accuracy12
bits (1mV or 5uA),the acquisition circuit can be configured as voltage mode
or current mode via wire jumper or resistor
Digital input4 channel, can be configured as active or passive input via resistor,
adopting interrupt I/O port, can collect the level and pulse signal
Digital output4 channels, can be configured as the relay output mode or transistor
output mode via wire jumper, the max load are respectively (10A/250V AC)
and (500mA/12V DC)
Data storageCan store historical data and real-time data,possess8MB serial FLASH, can
be expanded to 16MB and 32MB,possess256KB serial FRAM
Micro SD CardCan external connect TF card, support FAT32 file system
Real-time clockAdopting high precision clock chip, the error does not exceed 5 seconds /
year, ensuring 3 years operating under the case of power down for the
back-up battery .
Power dissipationData doesn't transmit state≤60mA
Data transmitting state≤100mA

Serial Port Data Acquisition
RS232/RS485 interface can be externally connected to any sensor device, including
temperature and humidity sensor, gas sensor, speed sensor, soil sensor, pressure sensor, liquid
sensor, transmitter and motor protection sensor, etc. Also can be connected to various
instruments, PLC device and other external equipment like camera, can be arbitrarily selected
according to customer's demand.RS485 interface can be connected to multiple the same or
different device, supports up to 48 devices in series.
As long as the external device have RS232 or RS485 interface, in theory, our RTU serial port
can be connected.
