Typical Applications
Typical of applications for the 931U‐C9C7C‐BC is the
conversion of thermocouple temperature input
(low range of millivolts) into a high level (e.g. 4‐20
mA) value for transmission to a control system.
In this type of installation the 931U‐C9C7C‐BC pro‐
vides:
• Linearization of the standard thermocouple
temperature/millivolts characteristic.
• Isolation of the input signal to the control sys‐
tem. This allows the user to use a thermocouple
with a grounded hot junction for a quick re‐
sponse at the measurement point. This would
otherwise convey electromagnetic influences
(high frequency noise) into the control system.
• Selectable output value for a thermocouple‐
break event.
• Flashing LED status indicator on the unit front on
thermocouple‐break.
• Relay alarm output if required on thermocouple‐
break.
• Relay alarm output on high or low process tem‐
perature.
