1.1.1 GENERAL
This instrument is a microprocessor based single loop controller capable of measuring,
displaying and controlling temperature, pressure, flow, and level from a variety of inputs.
Control functions, alarm settings and other parameters are easily entered through the front
keypad. All user's data can be protected from unauthorized changes with it's ENABLE MODE
security system. Battery back-up protects against data loss during AC power outages.
The input is user configurable to directly connect to either thermocouple, RTD, mVDC, VDC
or mADC inputs. Thermocouple and RTD linearization, as well as thermocouple cold junction
compensation is performed automatically. The sensor input is isolated . The instrument can
operate on either 115VAC or 230VAC power at 50/60Hz. It is housed in an extruded alumi-
num enclosure suitable for panel mounting. It may be surface mounted using an optional
adaptor.
