RMA PLUS Remote Access Module
Watlow’s new RMA PLUS remote access module supports Watlow’s powerful EZ-ZONE® RM temperature controller family by communicating with and providing access to all EZ-ZONE RM modules in a system.
EZ-ZONE RMA users have had to spend more time than desired to connect their entire system. Now 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 device 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.
Because the RMA PLUS is an essential component of the EZ-ZONE RM family, users receive all the benefits and support of working with Watlow®.
Benefits of using an integrated controller solution:
-Reduces wiring time and termination complexity compared with connecting multiple discrete products
-Improves system reliability
-Reduces termination and installation cost
-Eliminates compatibility issues often encountered with using various discrete components and brands
-Reduces troubleshooting time and downtime costs because the system can specifically identify any problems with a sensor, controller, solid state relay (SSR) power output or heater load
-Complete thermal solution saves engineering time and labor costs while shortening project schedules
Multiple inputs; from 1 to 152 PID loops of control or monitor up to 256 analog inputs
-Mix and match I/O to fit any application; from 1 input with 2 outputs to 152 analog inputs with 152 outputs, or monitor up to as many as 256 analog inputs all in one system
-Reduces cost because only required loops are purchased
-Allows a common controller platform across many design applications as both loops and outputs can be ordered in single increments
Additional Key Functions:
-Configuration communication port (standard bus)
-Removable modules and connectors
-Ring lug and front-screw terminal options
-Profile ramp soak with 400 total steps
-Retransmit and remote set point input virtually inside controller eliminating costs for input/output hardware
-User configuration settings can be stored and recalled
-Elevated operating range of 0 to 149°F (-18 to 65°C)
-UL® listed, CSA, CE, RoHS, W.E.E.E. FM, SEMI F47-0200, Class 1, Div. 2 rating on selected models
