The RTU (Remote Terminal Unit) controller based on SO-52v21 is designed to perform control and supervisory functions in medium voltage switchgear stations (MV-S), controlled via a network link or wirelessly.
RTU SO-52v21 performs measurement and control functions required in power automation, especially when working in a simplified structure. The device can be used in power stations, power plants, chemical plants, sewage treatment plants and others. Large communication resources enable operation in various communication networks based on Ethernet, GPRS/GSM transmission, radio transmission in dedicated and open channels, modem transmission in public telephone networks or separate networks.
Small dimensions and extensive communication capabilities make the controller particularly useful in SMART GRID applications.
The parameters of the application software can be edited using the specialized pConfig configuration program to provide the functionality required by the user.
RTU SO-52v21 provides a high level of user security thanks to the built-in "cyber security" mechanisms that ensure data protection and confidentiality, certainty of operations, protection against unauthorized operation and counteracting human errors. Communication protection mechanisms, remote and local access and protection of sensitive data have been implemented.
The device can be powered with different voltages depending on the user's needs. When an application requires increased system reliability, the device can be provided with a buffered redundant power supply.
The device is mounted in a metal housing type RXA with dimensions of 350 x 430 x 250mm (WxHxD) and is shown in the picture on the right.
Example elements of the RTU SO-52v21 controller:
Safe communication in the SO-52v21 series devices can be carried out through various transmission media, such as Ethernet in the 100Base-TX, 100Base-FX standard, galvanically separated serial links SR-232 and RS-485 or through dedicated fiber optic links. []
