Basic circuit diagram connection of signal and power ISOll3

Posted on Mar 28, 2007

As shown for the basic connection circuit ISO113 signal and power supply. Each power supply terminal must have a bypass filter. When isolated power supply output current is gre

ater than 15mA, we recommend the use of such power pin + Vcc1 pin external Ji filter. Isolation rectifier output pin ( Vcc2) and amplifier input supply pins ( Vc) can be attached to the ripple filter or calibrator. Com1 feet to the signal source, Sense then load the upper end, to reduce the transmission due to the long wires cause a voltage drop caused by the error. Gnd1 connected to Com1, VOUT and Sense in the relative socket connection, or TTL low will disable the internal DC-DC converter works. Internal transformer coupling DC/DC converter by the isolation amplifier input power, all power has feet within a 0.1 F capacitor to ground.
