The PLC-K632-02IV is an Analog Output Expansion Module that reads in a digital value from the PLC and outputs either a voltage or current that reflects that digital value. This unit has a 12-bit digital output resolution allowing the user to increment in 976 μV or 3.9 μA steps. The PLC-K632-02IV can output a current range of 0-20 mA or 4-20 mA, and a voltage range of 1-5 VDC or 0-10 VDC. The K631 series has an accuracy of +/- 0.5% to ensure a precise reading. These modules are attached to the PLC-K6 CPU series to provide analog output capabilities. Up to 6 of the analog output modules can be attached to the K6 series CPUs, allowing for a maximum of 12 analog outputs or 14 analog outputs if using the PLC-K606EA-30AT.
