Product Description 1.1
1.1.1 GENERAL
The instrument is a microprocessor based circular chart Recording Profile Controller capable
of measuring, displaying, recording and controlling a variety of inputs. Applications include
temperature, level, pressure, flow and others. The instruments can be specified as either a
single or as a dual pen model. The second pen can be selected as a profile control or a
single setpoint control.
Recording, control functions, alarm settings, profile entry and other parameters are easily
entered via the keypad. All user data can be protected from unauthorized changes by the
Enable mode security system, and is protected against memory loss, as a result of AC power
outage, by battery back-up.
The process sensor input for each terminal block is user configurable to directly connect to
either thermocouple, RTD, mVDC, VDC, or mADC inputs. Changes in input type can easily be
made by the user. Thermocouple and RTD linearization, as well as thermocouple cold
junction compensation, are performed automatically. The instrument process variable inputs
are isolated. An isolated 24 VDC regulated transmitter power supply can be provided in the
instrument for use with up to two 4 to 20 mADC process sensor transducers.
The instrument can be ordered to operate on either 115 VAC or 230 VAC power at 50/60 Hz.
The 230 VAC option includes a switch for selecting either 230 VAC or 115 VAC operation.
The instrument is housed in a structural foam enclosure suitable for panel or surface
mounting.
