ABSTRACT:
A self contained data acquisition and control system and apparatus with direct process input and output capability. Designed to operate within the harsh environment of a process zone, the apparatus employs a variety of process monitoring and control modules which perform under the direction of redundant computer controllers. These controllers provide control data loading to the modules as well as receive and transmit process status data. The modules are each formed having a hardware control and status monitoring circuit which performs in conjunction with a module microprocessor based control. One module provides for field contact actuation in combination with a technique for deriving data signals form the contact and associated field wiring for evaluating the performance of those same field contacts. Another module provides an isolated electronic switch output wherein the battery power supply or the like is provided with the control apparatus and the status of the load, the power supply and the switch itself is ascertained, while a third analog output module uniquely combines two analog outputs in redundancy an further exhibits status monitoring including full loop status monitoring from the point of derivation of the analog output at a digital analog to converter to the return current from the load itself.
