Remote Terminal Units

AEMT. AEMT RTU has been specifically designed for controlling cathodic protection systems which are usually in charge of protecting buried metal pipes. Equipped with a GSM/GPRS modem and 3 analog inputs and 4 digital inputs, the AEMT RTU can increase its I/O capacity thanks to its RS-485 bus. Its main purpose is to automatically calculate the out of service and out of limit times of the cathodic protection system. 

RDP. RDP RTUs are low power consumption devices (18 months battery powered). Each RTU has 8 inputs (3 analogs, 4 digitals and 1 counter) and it is equipped with an integrated GSM/GPRS modem. RDP RTUs are particularly suitable for datalogging and water pressure monitoring (waterproof IP67 container).

I/O Cards. I/O cards are designed and built by Staer: they contain microcontroller for data acquisition and local pre-processing such as filtering of fast transitions, digital output (DO) programmable duration, variable gain of analogue input (AI), pulse output and so on. There are several I/O card types available such as, for examples, analogue and digital input data acquisition and E1 radio-links quality analyzers. All cards integrate protections against Electrostatic Discharges and lightning surges.

RTU3G. RTU3G is a high performance and capacity RTU suitable for a broad range of applications. RTU3G enhances MPTS capabilities in challenging applications which need high performance in terms of I/O, process control and processing power.

MPTS. MPTS is a family of mid-size RTUs suitable for a broad range of applications. MPTS RTUs can be equipped with up to two 16-bits or 32-bits CPUs. MPTS RTUs can be customized for different applications by equipping them with accessories such as temperature sensors, power supply sensors and trasducers. Analog, digital and counter inputs are acquired by a RS-485 bus which, in turn, can be also used to connect several RTUs into a local network. Interactions with control centers, displays and other devices are carried out either via serial lines or Ethernet. A broad range of wireline, wireless and satellite communication systems as well as a library of standard and proprietary protocols enable MPTS RTUs to be linked to control systems and other field devices. MPTS RTUs are usually deployed within mounting kits which can easily fitted for any location and condition. Site security is enforced by the MPTS RTU ability to manage access control via Radio Frequency IDentifier (RFID) tags. MPTS RTUs have very low power consumption and can be also equipped with solar arrays.

Simply, RTU is a control or data collection unit situated remotely to the main control and monitoring system. For example RTUs can be used for read out tank levels or monitoring pump functions. Staer RTU product family is providing Staer Customers and Partners with the reliability and performance required to monitor complex infrastructures and networks. I/O cards contain microcontrollers for data acquisition and local pre-processing and a wide library of protocols is supported to interface external devices and communication lines.

Staer RTUs are available in two basic families:

Staer RTUs are real-time systems with a very flexible hardware and a powerful software. Easy maintanability, flexible installation, performance and ability to work also under very tough conditions make Staer RTUs suitable for any assignment, customer site and future growing.

Staer is a leading developer and manufacturer of Remote Terminal Units (RTU) for Energy, Environment, Broadcast and Telecommunication market segments.
