Plug-in Signal Conditioners M-UNIT

PULSE DURATION TRANSMITTER

Functions & Features

• Converting a DC input into an output pulse

• The duration or "ON" time is linearly proportional to the

input analog signal amplitude

• Frame duration adjustable

• High-density mounting

Typical Applications

• Transmission or telemetering

• Proportional ON-OFF control to operate solenoid valves or

other similar final control elements
