Product Details

The ProSoft 5201-104S-103M is a standalone ProLinx protocol gateway built for power substation telecontrol systems. It acts as a bridge that converts data between IEC 60870-5-104 server and IEC 60870-5-103 master protocols. It is equipped with one Ethernet port for IEC 104 network communication and one configurable serial port running as IEC 103 master, which can connect and communicate with up to 16 IEC 103 slave protection relays and IED devices. The gateway supports bidirectional data mapping for analog measured values, binary status, fault events and counter data, and it can send spontaneous event messages to the upper IEC 104 SCADA client.

This gateway adopts standard DIN rail mounting for installation inside control cabinets. It is powered by 24 VDC industrial power supply and carries multiple LED status indicators for power, network activity, serial communication and fault alarm, which simplifies on-site commissioning and troubleshooting. Users can complete point mapping, polling configuration and diagnostic checking via ProSoft Configuration Builder software. It provides complete communication diagnosis functions to monitor link status, error codes and real-time data transmission. It has strong EMC performance to adapt to harsh electromagnetic environments in power substations, and the operating temperature range is 0°C to 55°C for stable continuous operation.

This protocol gateway is widely used in power substation automation, relay protection integration, energy monitoring, power plant auxiliary control and legacy telecontrol system upgrade. It allows existing IEC 103 protection devices to be seamlessly integrated into IEC 104 SCADA networks without modifying the internal logic of protection equipment. As a discontinued legacy communication gateway, the 5201-104S-103M is mainly supplied as spare replacement parts for running power automation systems. It maintains reliable cross-protocol data transmission, preserves the original control architecture and reduces the cost of system reconstruction.
