Marathon Monitors Inc.

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 +1oC.

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.).
