Siemens ARGUS-7SR1003 Series Monitoring Relay, 60 to 240V Supply Voltage, 5A Relay Contact Current - 7SR1003-2KA20-2CA0

This monitoring relay provides non-directional overcurrent protection and control for industrial power systems. It accepts 1A or 5A measuring inputs and operates with AC or DC auxiliary supplies, offering integrated breaker control and multiple communication options for supervisory systems. The unit includes digital inputs and outputs for external signalling and supports serial protocols for remote interrogation.

Features and Benefits:

• 60 to 240V DC supply enables flexible auxiliary powering options
• 240V AC/60V AC operation supports varied AC supply networks
• 1A/5A current sensitivity allows precise CT compatibility
• ANSI50BF circuit breaker failure function ensures backup tripping
• 5A relay contact current provides direct signalling and interlock

Applications

• Suitable for feeder overcurrent protection in substations
• Ideal for integration with SCADA via serial protocols
• Used with breakers for trip-circuit supervision and control
• Can be used for negative-sequence unbalance detection
• Suitable for networks requiring sequence-of-events recording

Which communication protocols does it support?

It supports IEC 60870-5-103, Modbus RTU and DNP3.0 over RS485 and a front USB port.

What inputs and outputs are available for interfacing?

It provides up to four current inputs, six digital inputs and six digital outputs including signalling contacts.

How is time synchronisation achieved?

Time synchronisation is provided via binary inputs or the communication channel.

What environmental range does it tolerate?

It is rated for continuous operation between -10°C and +60°C.
