The newest model in Sensoray's 2600 series, the 2652, uses a single category-5 patch cable, connected to a 2601 communication module, to monitor and control up to eight solid state relays. Each of the relay sockets can have either an ac in, ac out, dc in, or dc out relay. The module uses a software debounce filter on each input relay to cut down on electromechanical switch bounce errors. The client can control the relay while configured as an output, or the relay can run as a PWM output with a rate and duty cycle specified by the client. There are five independent interlock circuits for letting external circuitry such as an emergency stop switch to de-energize an output relay.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
