September 8, 2014 - Intelligent-Appliance announces IA-3121-E, a 32-ch Solid-State Relays Control card that provides 1Amp on each output, fully protected, aimed at Inductive Loads and Resistive ones. 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. This compact structure may be used as a Power Digital Output creature with an Output Sink current of over an Amp, ideal tool for operating Led Lamps, Solenoids or any other load that should be operated thousands of times an Hour without adding the original relay clicking noise and its end of life counting down watch, getting closer each tick. The IA-3121-E is controlled by a TCP/IP port and may be used as an RS-232 expanding port as well, chaining RS-232 boards to the Ethernet net.
