The Watlow EZ-ZONE RMA PLUS Remote Access Module supports Watlow's EZ-ZONE® RM temperature controller family by communicating with and providing access to all EZ-ZONE RM modules in a system. The RMA PLUS offers standard state-of-the-art connectivity from the device to the entire system. Real-time communication is possible via a built-in ethernet switch or USB. Users can also connect to third-party and legacy devices because the RMA PLUS acts as a gateway between Modbus® TCP and Modbus® RTU.

The RMA Plus comes standard with a built-in managed ethernet switch with two ethernet jacks. Up to three Modbus® TCP sessions, three Watbus over ethernet sessions and one Watbus over USB session is available in a single device. Users can also log up to 16 gigabytes of data standard or upgrade to a maximum of 32 gigabytes. Configuration and data logs are available as Windows® files so they can be easily accessed. In addition, discovery and transfer speeds have gone from minutes with the legacy EZ-ZONE RMA to just seconds with the RMA PLUS.

The RMA PLUS easily integrates into the EZ-ZONE RM family with plug and play access. The built-in ethernet switch eliminates the need to provide a switch for small systems. It offers port mirroring for troubleshooting and protects from broadcast and multicast storms. The integrated USB connection provides easy connection from PC with no converter and ensures real-time communication from software packages. The Modbus® TCP and Modbus® RTU allow users to build tables based on individual needs. All modules ship with standard bus protocol (Watbus) for configuration and communication connection to all EZ-ZONE products
