J Type Thermocouple/4-20mA Converter

The thermocouple to 4-20mA converter is useful when monitoring very high or very low temperatures that can not be monitored with a standard SNPALM temperature sensor. Thermocouples are available in a variety of packages that may be perfectly suited to your measuring application. Each thermocouple input module provides a single channel of thermocouple input which is filtered, isolated, amplified, linearized and converted to a 4-20mA output. Isolation is provided by transformer coupling, using a proprietary technique to suppress transmission of common mode spikes or surges. The modules have excellent stability over time and do not require recalibration.
