Mini RTU by ELSETA is the most versatile modular solution for secondary substation automation for distribution network operators, utility companies, and factories. Designed for a broad range of applications, ELSETA’s Mini RTU originates from a WCCLite combination with optional I/O modules.
More information about all features you can find here.
Mini RTU by ELSETA collates up to 3000 signals (together with I/O modules) for direct routing to SCADA systems over IEC60870-5-101, IEC60870-5-104, DNP3 or Modbus protocol. Measuring just 12 x 2 x 10 cm, this compact RTU fits into smaller enclosures and saves DIN rail space, reducing its cost of installation. Mini RTU by ELSETA communicates with the control center through an integrated 2G/3G/4G(LTE) modem. It also has LAN and WiFi interfaces for easier configuration and access.
The choice of different input/output modules gives you freedom for system extension. The core WCC Lite unit communicates with I/O modules through Modbus (RTU) or IEC60870-5-103 protocol. Adding and configuring each I/O module is almost Plug’n’Play.
Supported protocols:
- Modbus master/slave (RTU/TCP)
- M-bus master (Serial/TCP)
- DLMS/COSEM (Serial/TCP)
- IEC62056-21 (Serial)
- IEC62056-31 (Serial)
- IEC60870-5-101 master/slave
- IEC60870-5-103 master
- IEC60870-5-104 master/slave
- DNP3 level 3+ master/slave (Serial/TCP)
- IEC61850 client (optional)
- Transparent tunnel from TCP to Serial
- MQTT
- Restful API
Mini RTU is an ideal solution for distribution substations and MV switchgear:
- Operating temperature ranges from -40 to +85 °C, enabling Mini RTU to work in the roughest weather conditions
- One of the highest cybersecurity levels in the market
- Integrated communications: 2G/3G/4G(LTE), WiFi or LAN interfaces onboard, with optional dual SIM modems for the highest reliability
- Easily scalable by combining individual I/O modules via Plug’n’Play
- Long product life-cycle and high investment security
