Isolated dual output frequency trip amplifier

The K111 is a dual output isolated trip amplifier/converter for on/off sensors, also featuring input repeater and frequency divider till 256. Maximum frequency is 20 kHz. The input stage is adjustable to almost every kind of sensor type, and it is provided with an isolated stabilized supply, that makes it suitable both for 2 and 3 wire devices. The module has to be PC programmed through S117P (RS232-TTL/USB converter) interface, both for output and led functions. Outputs are strong, internally protected PNP type. K111 offers built-in isolated, protected and stabilized power supply at sensor side and ensures pulse input for all the most common sensors: mechanical contact, Iec1131, Namur, 2 or 3 wire Npn/Pnp with 12 V or 22 V, reed, photo-transistor and Hall devices. The module has two free programmable 200 mA PNP outputs, internally protected and a 1500 V galvanic isolation between input and output side. Input type is settable by four dip-switches. It’s also available a programmable filter for false-frequency rejecting. Other programmable features are: threshold, hysteresis, window range, inverted output, indicator front leds. Interesting application are in refinery and agricultural company as oil measure conversion for abolition of tax and cost-saving rate. K111 can be applied also in transportation and industry automotive sector as pulse divider. For example to measure RPM using a proximity sensor near a toothed weel connected to a drive shaft.
