Houston, TX, September 09, 2014 --(PR.com)-- The new Intelligent-Appliance High Efficient Solid-State Relay card, the IA-3121-E, handles 12 to 30VDC loads with a tiny voltage drop of 60 millivolts keeps temperature down as well as space volume.
In addition to advanced microprocessor technology, the EWTC comprises an indirect heat exchanger for process cooling, and solid-state relay controlled immersion heaters for quiet, reliable and fast operation.
The switch is available with two solid-state relays or a solid-state relay plus an analog output.
It features a PID temperature controller already connected to a high-amperage, solid-state relay, with the option of adding a properly sized heat sink, current measurement, over/under temperature limit, definite-purpose mechanical contactor, and digital communications.
Both products are designed for interfacing a variety of real-world I/O, including industry standard solid-state relay (SSR) racks.
It offers an adjustable 4-20 mA analog output and two solid-state relay switches.
The LR1200480D40 is a DC-controlled, AC solid-state relay capable of controlling up to 40A at a line voltage of 480 VAC.
The I/O complement includes four contact-sense discrete inputs, two of which can be configured by software as pulse inputs; two dry-contact solid-state relay outputs; three single-ended voltage-sense analog inputs; and one current-loop analog output.
A MOSFET or IGBT will generally cost more as the output device in a solid-state relay than SCRS.
Introduced in 2003, the Geflex family was the first to combine a PID controller, power solid-state relay (SSR), current transformer, and digital communications in one device (above).
It features a PIP temperature controller already connected to a high-amperage solid-state relay, with the option of adding a properly sized heat sink, current measurement, an over/under temperature limit, a definite purpose mechanical contactor, and digital communications in one package.
The new Allen-Bradley Bulletin 700-HL terminal block relay line, a 6.2-mm-wide interface, is available with a one-pole (SPDT) relay or one normally open solid-state relay and offers reduced space requirements and installation costs for a variety of high-density isolation and interposing applications.
