The 8B49-01 is a voltage-output isolation module that accepts a 0V to +5V input and provides a -5V to +5V output. It features 1500Vrms isolation, 110dB common-mode rejection, and 80dB per decade normal-mode rejection above 100Hz. The output is protected against continuous 40VAC overvoltage and transient events per ANSI/IEEE C37.90.1. The module operates with +5VDC power, draws 100mA at full load, and has a bandwidth of 100Hz with a 5ms response time. It meets UL/cUL listing and CE compliance, is certified for Class I, Division 2 hazardous locations, and is manufactured to RoHS III standards. The package measures 1.11" x 1.65" x 0.40" (28.1mm x 41.9mm x 10.2mm) and operates from -40°C to +85°C.
8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 8B49 module accepts an input signal from a non-isolated source, then isolates, filters and converts the signal to a high-level process voltage output.
Signal filtering is accomplished with a 4-pole filter optimized for time and frequency response which provides 80dB per decade of normal-mode rejection above 100Hz. One pole of this filter is on the system side and the other three are on the isolated field side.
A special output circuit in the 8B49 module provides protection against accidental connection of power-line voltages up to 40VAC continuous. Clamp circuits on the I/O and power terminals protect against harmful transients.
The modules are designed for installation in Class I, Division 2 hazardous locations and have a high level of immunity to environmental noise.
