PCL is a power AND data fieldbus system for controlling and monitoring EHS actuators, pumps, tank level sensors, etc. The PCL system significantly simplifies electrical installation. A single cable is used for power supply and data communication. Connecting all actuators and IO nodes via a simple cable loop saves a lot of cable and wiring effort.

• For all types of EHS actuators
• IO modules for tank gauging, pump control, etc.
• Up to 250 participants can be controlled by one bus master
• Each bus master provides up to 8 data loops and up to 8 power loops
• Local control panel for emergency operation and setup
• Connection to higher-level control system via redundant Modbus RTU
• Single fault-tolerant system
• Even with an interruption or short circuit of data or power circuits, no more than 2 nodes are affected by a fault
• Interruption or short circuit of data or power lines
• All faults are indicated and localized
• Redundant bus masters in hot-standby operation
• Separate BUS master for SRTP solutions
