The Watlow EZ-ZONE RM EtherCAT adapter provides up to 48 loops of PID temperature control and monitoring over an EtherCAT network. The adapter uses existing EZ-ZONE RM (Rail Mount) Scanner modules for sensor inputs and existing EZ-ZONE RM Expansion modules for outputs. The adapter module provides EtherCAT connectivity, PID loop control, and alarm functionality as well as connecting point for legacy products. The system can be enhanced with over-temperature limits, heater measurement and programmable logic blocks. The system is ready-to-run out of the box with minimal configuration. The EtherCAT interface is the ETG 5003.2060 Semiconductor Temperature Controller Device Profile.
The available sensor types are thermocouple, RTD, 4-20mA, and 0-10V or thermistor. The outputs as available as open collector/switch DC, 2.0 amp SSR, or mechanical relay. Each loop provides two alarms: 1 process and 1 deviation. The system scales in 4 loop groups. The EZ-ZONE platform delivers proven, rugged and accurate I/O with autotuning PID or On/Off control.
The RM EtherCAT adapter also bridges to legacy Watlow products such as the EHG-SL10 line heating system and CLS multiloop controllers via Modbus. It also provides an HMI port for connecting Modbus user terminals such as the Watlow Silver Series. There is a optional Bluetooth interface for users that want to monitor and diagnose their system from a smart phone or tablet in the lab.
The RM system is DIN rail mounted and powered from 24V AC/DC. It is UL/CUL listed, ROHS compliant, and CE rated.
