DSCP62 Configuration Guide

Thermocouple-to-DC Current/Voltage  
Converter with Relay Output

Description

Each DSCP62 Thermocouple Converter provides a single channel of thermocouple 
input which is amplified, linearized and converted to a high-level current or voltage 
output. Thermocouple type, measurement range, filter, output type and range, 
and fault indication may be configured by dip-switch. An auxiliary relay output 
is provided to generate an alarm or act as a thermostat. Power can be applied 
directly to the converter’s terminals or through a DIN rail mounted bus connector 
accessory, eliminating the need to wire power to each individual converter.

Installation rules

This module is designed for assembly on a DIN 46277 rail. Assembly in a 
vertical position is recommended to increase the module’s ventilation. Be 
sure that no raceways or other objects that compromise aeration are posi-
tioned in the vicinity, and do not position the module above equipment that 
generates heat. We recommend positioning the module in the lower part of 
the control panel or container compartment. We also recommend rail-type 
assembly using the Power Bus connector, which eliminates the need to con-
nect the power supply to each module.

Auxiliary Output

The auxiliary output is designed to drive an indicator, a relay of greater 
power, or the input of a supervisory control system. Through this output the 
DSCP62 module can generate an alarm or be utilized like a thermostat. The 
normal state of the output depends on the configuration for the fault of the 
primary output.

Setting the threshold

The regulation of the threshold is performed through a button located under 
the front cover of the module and accessible through the hole using a small 
screwdriver. 

•  Press and release the button. The primary output will start to represent 

the value of threshold and the red LED will flash slowly.

•  If the button is not pressed again within 5 seconds, the system will 

return to standard functioning.

•  Each time the button is pressed there is an increase or decrease of the 

primary output of approximately 0.2%; the direction of the variation 
depends on the configuration of the output. 

•  If the button is not released but continues to be pressed, a continuous 

3% increase starts after 2 seconds.

•  When the maximum/minimum value of the chosen scale is reached, the 

cycle starts again.

•  During regulation of the threshold, the auxiliary output follows standard 

functioning, opening and closing as previously set.

•  After 5 seconds of no button pressing, the set value is memorized and 

the module continues with standard functioning.
