Features Interfaces to Potentiometers up to , • High-Level Voltage Output xcitation for the potentiometer is provided by using two matched current sources. When using a 3-wire connection, this method allows equal currents to ow through the sensor leads, canceling the effects of lead resistances.The excitation currents are small (equal to or less than 0.25mA) which minimizes self-heating of the potentiometer. • 1500Vrms Isolation • ANSI/IEEE C37.90.1 Transient Protection • Input Protection to 240VAC Continuous • 120dB CMR Signal filtering is accomplished with a pole filter optimi ed for time and frequency response which provides 70dB of normal-mode rejection at H . One pole of this filter is on the field side of the isolation barrier for anti-aliasing, and the other two are on the system side. • 70dB NMR at 60Hz • ± 0.05% Accuracy • ± 0.02% Linearity A special input circuit on the 8B36 module provides protection against accidental connection of power-line voltages up to 240VAC. Clamp circuits on the I/O and power terminals protect against harmful transients. Low Drift with Ambient Temperature • C-UL-US Listed • CE Compliant The modules are designed for installation in Class I, Division 2 hazardous locations and have a high level of immunity to environmental noise. • ATEX Compliance Pending • Mix and Match Module Types on Backpanel Isolation Barrier –EXC 3-wire 2-wire Slidewire Potentiometer – Jn (1) – +EXC +EXC 3 Surge Suppression and Protection LPF 6 7 +V 2 VOUT COM –V Computer-Side Power 4 + + Iso-Chopper™ Amplifier Pat.
