Features and Benefits
Key component of a Watlow ecosystem solution
- Integrates with EZ-ZONE® RM, RMA PLUS™ and PM PLUS® controllers for a complete solution including Modbus® TCP, EtherNet/IP™, or EtherCAT® communication
- Eliminates discrete wiring between temperature controllers and power controllers for each heater through the highspeed backplane interface with Watlow controllers
- Enables data collection and diagnostics from the power controllers
- Customizes for your application with programmable function blocks including logic, math, compare and more
High accuracy current and voltage measurement
- Characterizes process performance
- Supports comparing (fingerprinting) equipment operation
Integrated, scalable solution
- Allows connection from the temperature control system at one point communicating with up to 16 power controllers
- Offers greater than 60% reduction in wiring footprint and costs compared to other multi-zone systems
- Eliminates need for current transformer and associated wiring with integrated current measurement
Industry-leading design and serviceability
- Offers a robust SCR design to meet a rugged industrial environment’s high quality and reliability needs
- Enables fast troubleshooting by providing helpful thermal system diagnostics
100KA short circuit current rating (SCCR)
