The PCM4 is a stand alone isolation card designed to work with any of the Minarik Drives products that can accept a remote analog signal for control. Any application that involves controling a motor drive with a remote analog signal requires isolation. The isolation can be at the signal source, such as in a PLC, or it can be on the drive end. Some Minarik Drives families always have isolation by default, others have isolation as an option that must be populated at the factory, and a few have an adder board that can be installed remotely in the field after initial installation. For all other drives, the PCM4 is a necessary component to achieve remote analog control.
Powered by a 115 or 230 VAC single phase power source, the PCM4 can accept any DC voltage signal between -250 to +250 VDC, or a current signal of either a 1-5, 4-20, or 10-50 mA range. The PCM4 converts any of those analog input signal ranges into an isolated -12 to +12 VDC range @ 10 mA with a 0.01% linearity. High resolution multi-turn trim pots can be used to scale that output range to match the required input of any Minarik Drives control.
