DC Input Fixed Range Isolated Transmitter Model DM4300A
The DM4300A is a fixed range DC to DC isolator that provides an isolated current or voltage output proportional to a current or voltage input.
The DM4300A is also available in a high speed version that is useful in motor control feedback circuits and other applications that require fast response time.
The DM4300A includes filtering and conditioning to reduce susceptibility to transients and noisy environments. 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. These terminal blocks allow the product to be removed without unwiring the connections.
