Product Description 1.1
1.1.1 GENERAL
The instrument is a microprocessor based circular chart recorder capable of measuring,
displaying and recording from a variety of inputs. Applications include temperature, pressure,
flow and others. The instrument can be specified as either a single or dual pen unit.
Recording, alarm, or limit settings 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 variable input for each terminal 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, is 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 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 recorder is housed in a structural foam enclosure suitable for panel or surface mounting.
