Partlow MRC 8000 - 12" Circular Chart Recorder/Controller
The MRC 8000 Recorders and Recording Controllers are microprocessor based, 12 inch, circular chart instruments capable of measuring and displaying, recording and controlling up to two process variables from a variety of inputs. Applications include temperature, pressure, level, flow, relative humidity, pH and others using the universal inputs. The instrument incorporates two 4 digit LEDs configurable displays to show either the process value only, process and setpiont, deviation from setpoint only, or deviation and setpoint while in the normal operating condition. They can also display the proportional control outputs and the process values sequentially. The MRC 8000 is housed in a structural foam molded enclosure which can be panel or surface mounted. Its design allows it to fit into the smallest panel cutout of competative products, while it covers the largest cutout of others. Glass and plastic windows are available, along with a cover lock. The standard enclosure carries a NEMA 3 rating, with an optional NEMA 4X available. The MRC 8000 is available with a full compliment of options. On recorders, process alarms of high or low limit capability are available. On controllers, process deviation, and deviation band alarms are available along with remote setpoint options. For transmitters, a 24VDC 40mA Transmitter power supply is available. Up to four SPST relays or SSRs and up to two isolated 4-20mA outputs can be added. PC/DCS communications is available via an RS-485 interface.
