General
Main PV Input range: +100mV, 0 to 10Vdc (auto ranging) and 3 wire Pt100.
Calibration accuracy: The greater of +0.2% of reading, +1 LSD or +1
o
C.
Cold junction compensation >30:1 rejection of ambient temperature, (for thermocouple
i/p).
Electrical safety
Standards: EN 61010, Installation category II, pollution degree
2.
CSA C22.2 No.142-M1987.
Installation category II: Voltage transients on any mains power connected to the
instrument must not exceed 2.5kV.
Pollution degree 2: Conductive pollution must be excluded from the
cabinet in which the instrument is mounted.
Isolation: All isolated inputs and outputs have reinforced
insulation to provide protection against electric shock. The
fixed digital inputs, non-isolated dc, logic, and the logic output
of dual output modules, are all electrically connected to the
main process variable input, (thermocouple etc.).
