Robust, reliable solid state relays are the industry's smallest

Carlo Gavazzi has introduced, what is believed to be, the first UL-certified solid-state relay and contactor combination in a compact 17.5mm width. The new RG series includes RGS panel mounted models rated up to 600V AC and 90A AC plus RGC versions with integrated heat sink attaining 20A AC in 17.5mm, 30A AC in 22.5mm widths.

With reduced space per unit, nominal ratings at 40°C and 100kA short circuit capability, this range provides silent switching of heaters and motors.

All solid state relays and contactors in the series are VDE approved and designed in accordance with the latest EN/IEC62314 norms. Also, unlike most such devices on the market, RG products are UL listed to facilitate machine approvals and inspections. They are robust and reliable, resisting up to 5g of vibration and featuring integrated over-voltage protection across the output. Dependable operation is confirmed by control status LED indication on the front of the device.

The new RG relays can be controlled with a DC voltage range of 4-32VDC, whilst AC controlled types have a voltage range 20-275VAC as well as 24-190VDC, thus covering standard control regimes such as 24VAC/DC or 110VDC. There is a choice of either Zero Cross or instant ON (Random) main voltage switching versions.

RGS relays can be mounted on any heat sinking surface and are designed so that the distance between the heat-sink mounting holes is identical to standard hockey puck solid state relays. They incorporate special stress-relief mechanisms to cater for excess forces during the mounting process.
