3.8.3 Two analog inputs for thermocouple measurement − EPM−S405
This module detects up to two analog control signals from the process level and transmits
them to the higher−level bus system.
Features
ƒ 2 analog inputs
ƒ For thermocouple type B, C, E, J, K, L, N, R, S or T
ƒ 16−bit resolution
ƒ Internal temperature compensation
ƒ Signal function is parameterisable
ƒ An LED indicates if an input voltage is outside the permitted measuring range
(
Stop!
Overvoltage at the inputs
The electronics of the electronic module are not protected against too high
input signals.
Possible consequences:
ƒ The module is destroyed
Protective measures:
ƒ Make sure that the signals and encoders connected match the measuring
range parameterised.
Mounting instructions
Variations in temperature within the module may affect the measuring accuracy.
Therefore please observe the following recommendations:
ƒ Do not place the module...
– directly next to the bus coupler module
– directly next to a power supply module
– in a position as the last module within an I/O system
ƒ If possible, the ambient temperature should be constant. After a change in the
ambient temperature, the module requires approx. 30 minutes until obtaining its
ensured measuring accuracy.
