The MM4130 provides a DC output voltage or current, fully isolated from input, line power and ground, proportional to a thermocouple input signal. It is useful in measuring temperatures with any type of thermocouple. Cold junction compensation is provided by a solid state temperature sensor embedded in the thermocouple terminal strip.
All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning.
The module utilizes a feedback VCO to develop a pulse train with a duty cycle proportional to the input signal amplitude. This pulse train is coupled through an isolator where the duty cycle is converted to a proportional DC level in the output circuits. This isolated output eliminates ground
loops, large common mode signals and other types of interference.
Upscale burnout protection is provided as standard. In the event the thermocouple opens, the transmitter output will go offscale high. Option B provides downscale burnout protection (transmitter output grows low).
TYPICAL APPLICATIONS
Eliminates ground loops and common mode signals for temperature monitoring, control and data acquisition.
