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 25°C unless otherwise specified.

Benefits

• Communications interface. Reduced wiring and I/O modules. Solid state relay can exchange data with the system controller via this interface.

• Reduced maintenance costs and downtime. Use of real-time data for prevention of machine stoppages during operation.

• Good quality products and low scrap rates. Real-time monitoring allows timely decisions for better machine and process management.

• Reduced efforts in troubleshooting. Distinguished faults to facilitate and reduce troubleshooting time.

• Configurable. The switching mode of the RG..CM..N can be selected to either ON/OFF switching or power control.

• Fast installation and set-up. The solid state relays on the BUS are automatically configured for fast set-up and prevention of incorrect settings.

• Compact dimensions. Slimline RG series for a minimum product width of 17.8 mm, 1x DIN, up to 37 AAC at 40°C.
