Description

The DM4130 provides an isolated voltage or current output proportional to temperature as measured with a thermocouple. Any thermocouple may be used, and types J, K, R, S, T, E, and N can be linearized.

A microprocessor controls span and offset settings, performs cold junction compensation calculations, and performs a table look-up for linearization.

The DM4130 includes filtering and conditioning to reduce susceptibility to transients and noisy operations. It 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 a pulse transformer to the output circuitry, where the duty cycle data is converted to a proportional DC output level.

Connections are made via two 4-pin terminal blocks. The lower terminal block is unpluggable, allowing the product to be removed without unwiring the output and power connections.

Typical Applications

Useful for temperature monitoring, control  and data acquisition.

Mounting

The module mounts on a standard H-35 DIN rail. A spring latch holds it in place. The module is demounted by using a screw driver to release the latch. The latch release is accessible at the bottom of the module.
