The DM7010 is a field rangeable frequency input signal conditioner. It provides several choices of voltage or current ouputs proportional to the frequency of the input. A Normal – Reverse selection is available which reverses the output signal logic (ie 20 - 4mA vs 4 - 20mA). The input is galvanically isolated from the output and power source.

Response time can be set by the user with a selection of jumpers on the front panel. The wide input voltage range allows the product to be used with low level magnetic pickups, for flow or speed applications, as well as digital signals or direct power line monitoring.

A selectable pull-up resistor allows the product to be driven from a switch closure or open collector transistor. It will also accept CMOS or TTL digital inputs.

The DM7010 is housed in an aluminum case with a stainless steel DIN rail mount. The terminals on the front are pluggable, for ease in wiring. The snap-on front cover has a write-on label.

Several power input options are available.

TYPICAL APPLICATIONS
Typical applications for the DM7010 are monitoring flow, conveyor speed, power line frequency on portable generators, and motor rotation speed.
