EMKO ESM-9910 - 3.6 Temperature Input Connection

3.6.1 TC (Thermocouple) Connection
3.6 Temperature Input Connection
3.6.2 RTD Connections
Note 1 : In 3-wire system, use always cables of the same diameter (min 1mm²)
Its necessary to use cable in the same gauge and type for doing the line compensation
properly.
Note 2 : Install a jumper between terminals 2 and 3 when using a 2-wire RTD.
Note 3 : If the distance is longer than 10 meters, use 3-wire system.
3-wire PT-100 connection
(with line compensation)
(Max. Line impedance is 10 W)
2-wire PT-100 connection
(without line compensation)
Input resistance is greater than 10 M W.

Connect the wires with the polarity as shown in the figure at left.
Always use compensation wire corresponding to
the thermocouple used. If present, the shield must
be connected to a proper ground.
