RGC..CM..N RGS..CM..N Description The RG..N solid state relays are the switching components in the NRG BUS chain. Similar to the RG..D..N, the RG..CM..N has integrated monitoring and a communication interface to provide variables and diagnostic information in real-time. The variables that can be read out are current, voltage, frequency, power, energy consumption, load and SSR running hours. The status of each RG..CM..N is accessible. Faults are specifically indicated to facilitate troubleshooting. With the RG..CM..N solid state relays it is additionally possible to control the outputs of the solid state relays via the communication interface. There are two variants, the RGx1A..CM..N is the zero cross relay including various switching modes such as ON/OFF switching, Burst, Distributed full cycle and Advanced Full cycle modes. The RGx1P..CM..N is the proportional control variant which on top of the aforementioned switching modes includes also phase angle switching and soft starting features. The RG..N cannot interface directly with the system controller (PLC) but needs to be configured in an NRG BUS chain (as explained further on). 1 NRG BUS chain can handle up to 32 RG..CM..Ns. The first RG..N in the BUS chain is connected to the NRG controller, whilst the last RG..N in the BUS chain has to be terminated with a BUS terminator provided with the NRG controller. The RGC..N (with integrated heatsink) output ratings go up to 660 VAC, 65 A whilst the RGS..N (without heatsink) output ratings go up to 660 VAC, 90 A. Specifications are noted at 25C unless otherwise specified. Applications Any heating application where reliable and precise maintenance of temperatures is crucial to the quality of the end product. Typical applications include plastic machinery such as injection machines, extrusion machines and PET blow moulding machines, packaging machinery, sterilisation machinery, drying tunnels and semiconductor manufacturing equipment.

Required for RG..D..N or external control mode of RG..CM..N *RGN-TERMRES 14 System Overview The NRG is a system consisting of one or more BUS chains that enable communication between the field devices (such as the solid state relays) and the control devices (such as the machine controller or PLC). Each NRG BUS chain consists of the following 3 components: the NRG controller the NRG solid state relay(s) the NRG internal BUS cables The NRG controller is the interface to the machine controller. It acts as the master of the BUS chain when performing specific actions on the respective BUS chain, and acts as a gateway for the communication between the PLC and the RG..N solid state relays. It is not possible to operate the NRG system without the NRG controller. The NRG controllers available are: NRGC The NRGC is an NRG controller with a Modbus RTU interface over RS485. The NRGC is addressed via the assigned Modbus ID (from 1-247). In an NRG system operating on Modbus it is possible to have 247 NRG BUS chains. NRGC-PN NRGC-PN is an NRG controller with a PROFINET communication interface. The NRGC-PN is identified by a unique MAC address which is printed on the facade of the product.
