Project Description


Distributed Remote Terminal Unit

Targeted for station telecontrol and automation of plants, substations or similar technical infrastructures, CLP 500RTU is a flexible and scalable distributed remote terminal unit and programmable automation system featuring multiple communication and I/O options as well as integrated HMI.

By adopting international or industry standards together with unified engineering, CLP 500RTU provides an open future-proof and straightforward solution that can integrate multi-vendor IEDs and scale according to investment plans.

CLP 500RTU can be deployed in different system architectures from compact systems to high-capacity RTUs including local SCADA and redundancy options. This enables users to select the best fitting solution by balancing cost and performance in light of system requirements.

The worldwide field-proven CLP 500 platform is complemented with a full range of services from training and product support to engineering, commissioning and maintenance that support the system throughout the whole life-cycle.
