The Partlow MRC 7000 Circular Recorder is microprocessor based and capable of measuring, displaying, recording, and controlling up to two process variables from a variety of inputs. These process variables include temperature, pressure, level, and flow. The MRC 7000 recorder offers three choices: a reliable 10" circular chart recorder, a powerful recording controller, and a versatile recording profile controller.
Standard Features of the MRC 7000 include:
• Universal input capabilities
• Isolated process input
• Process value display for each channel
• Two programmable alarms per channel
• Selectable scan rate
Other features standard to the MRC 7000 include sensor break and error fault detection, display / chart and process filtering, programmable output action on sensor break / error condition, auto / manual transfer, control setpoint limits, secured access system, and more.
Additionally, many optional features are available to the MRC 7000 Recorder: single or dual control output, NEMA 3 enclosure, retransmission of process variable, up to 6 relay and four 4 to 20mA outputs, remote setpoint input, remote run/hold, electric motor modulation, 24V DC transmitter power supply, and RS-485 communications. A recording profiler is also available as an option when you order the recording controller; this version of the recording controller profiles on one or two channels.
Recorder functions, alarm settings, and many other parameters are easily configured via the keys on the front cover of the MRC 7000 Recorder. All user-configured data can be protected against unauthorized or mistaken changes; this is accomplished by the Enable mode security system and protected against data loss due to power failure by a battery back-up.
