Solid-state relay provides smoother control

A multifunction solid state relay provides phase angle, distributed control and burst switching - features more usually found in more complex, high end devices.
Carlo Gavazzi has introduced a multifunction solid state relay that provides phase angle, distributed control and burst switching - features more usually found in more complex, high end devices.
Optimised for the HVAC, printing, short-wavelength infra-red (SWIR) lamps, lighting control and the plastics and rubber markets, the new RJ1P is ideally suited to temperature controllers that use an analogue output for switching single-phase heaters, lamps and other loads up to 18kW.
This solid-state relay can handle higher-power loads than other existing solutions relative to its compact platform.
It provides a significant addition to Carlo Gavazzi's established RJ family and offers plug-in replacement options for users of the existing RN1F.
In HVAC applications, solid state relays with distributed or burst fire switching provide smooth, accurate and reliable temperature control in comparison to a mechanical device.
Phase angle control is ideal for accurate lighting control without light flicker.
The relay takes up just 45mm on DIN rails, around half the width of competing relays: twice as many units can be placed in the same panel (or the same number in half the space), thus lowering overall system cost.
A green LED on the front panel indicates control input status, while a red LED shows status of the load through direct feedback circuitry.
Rather than using complex codes, DIP switch setting or inaccurate potentiometers, setup is via a rotary function selector switch on the front of the device.
Users can choose between five preconfigured control options, which reduces inventory requirements and costs.
There is comprehensive conformity with international standards, including IEC/EN 60947-4-3, EMC Directives 89/336 and EN61000-6-2.
The relay carries CE marking, as well as UL and cUL approvals.
