Multifunctional Protection Relay for Gen-Sets

S.I.C.E.S. S.R.L.

GC 315

Multifunctional Protection Relay for Gen-Sets.

8 digital inputs
4 digital outputs
Ethernet connection
Can-bus interface


Multifunction protection relay used to provide additional protection to installation in more demanded applications such as Medium or High voltage or Oil & GAS installations.

D-Pro features a Can-bus connection to integrate it into a DST4602 Evolution based control system, or alternatively it can be used stand-alone connecting to the control system via its Relays and Inputs.

Main features:

  • Size 242×177×41 mm
  • 3 Phase Voltage input
  • 1 Residual Voltage input
  • 6 Current Inputs
  • 1 Auxiliary Current Input
  • 1 Auxiliary Toroid Current Input
  • Can-bus connection to DST4602 Evolution

5 years warranty

5 Year warranty

With this experience, we ensure all our products have passed stringent Quality Assurance checks during design approval and production. In addition we also subject them to a unique and arduous 48 hour cyclic burn-in test, to weed out possible early life failures, which could otherwise happen in the field.

We design and build the SICES controllers to last, giving many years of worry free service. This is not an empty promise and most SICES controllers come with a 5 year warranty which guarantees against component failure and manufacturing defects. Quality products made in Italy.
