Customized “Least Gate” functions have been programmed into the Quad Signal Processor for use in a mine winder application. Using four voltage inputs, three outputs are produced which are dependent upon all of the inputs. A block diagram description of the operation of the unit as well as a written explanation was used to develop the functionality of the Quad Signal Processor. The main benefit over using a PLC approach is that it is compact and cost effective for applications which require several devices with the same function. The unit cost after the firmware has been written is the same as for a standard unit. 
Inputs can be:
Voltage: 0-50 mV, ±50 mV, up to 0-100 V or ±100 V. Standards are 0-10 V and ±10 V.
Current: 0-20 mA, 4-20 mA, 0-5 mA, 0-1 mA as well as bipolar current inputs up to ±200 mA. Standards are 0-20 mA and 4-20 mA.
Outputs can be:

Voltage: 0-10 V and ±10 V at up to 5 mA, with maximum ±12 V.
Current: 0-20 mA, 4-20 mA, 0-5 mA or 0-1 mA. Maximum 500 Ω.
Auxiliary supply can be 24 or 12 VDC.
