As a Keyence Visual KV Series Unit, this KV-16DT PLC is a super small programmable logic controller with built in a display. The KV-16DT unit is a base unit that uses direct current type power supplies with 10 inputs and 6 transistor sink outputs. This specific unit, KV-16DT, is unfortunately discontinued by Keyence. The type of model the KV-16DT unit is a DC power supplied base unit type. For this base unit maximum input power that should be supplied of voltage is 24 VDC (+10%, -20%). And less than 2 milliseconds of instantaneous outage is allowed at a time. Any more and the programming software can become corrupt. More information can be found in the manual. The KV-16DT unit weighs only about 180g. The Keyence Visual KV units should operate a temperature range between 0 to 50°C (32 to 122°F) and 0 to 45°C (32 to 113°F), and never freezing the unit. Storing the Keyence Visual KV Series units should be done at an ambient temperature of -20 to 70°C or -4 to 158°F, but never freezing. Condensation can damage the KV-16DT's internal components. The appropriate humidity for the Keyence Visual KV Series Units should be operating around 35 to 85% RH. This KV-16DT Keyence unit will consume an internal current of no more than 90mA, with a 24VDC conversion value. If there is a continuous frequency of vibration, this unit KV-16DT, can only with stand an amplitude around 0.035 mm *1 at a frequency of 10 to 57 Hz.
