Mighty Module MM4001 Input Transmitter


MM4001 RTD Input Transmitter

Mighty,Module,MM4001,Input,TransmitterDescription

The MM4001 provides an output voltage or current proportional to an RTD input signal. It is useful in measuring temperatures with a variety of RTDs.

The module includes filtering and conditioning to reduce susceptibility to transients and noisy operations.

The module utilizes a single constant current source to excite the RTD. An accurate and stable lead wire compensation circuit uses the third lead of the 3-wire RTD to compensate for the RTD lead resistance.

Typical Applications

Temperature control, monitoring, and data acquisition.

Mounting

The module is designed to plug into a standard 8-pin relay socket. Part number MP008 is a molded plastic socket suitable for mounting on a flat surface or in a 2 3/4 inch wide PVC snap track (TRK48).  Use CLP-1 hold-down clip if needed. A Killark HK Series explosion-proof housing with dome and 8-pin socket is available (HKB-HK2D-8).  A DIN rail mounted socket (DMP008) is available for 35mm symmetrical DIN rail.
