Two new signal conditioning modules, the Adam-3112 and Adam-3114. The Adam-3112 is an isolated ac voltage to dc voltage module, while the Adam-3114 is an isolated ac current to dc voltage module. These two signal conditioning modules can convert up to 400 Vac or 5 Aac signals to 0~5 Vdc signals for data acquisition cards to measure while reducing the harmful effects of ground loops, field noise and electrical interference. Both modules provide 1,000 Vdc between output and power, as well as 2,500 VRMS between input and output and between input and power. The 3112 provides three input modes, 0~120 VRMS, 0~250 VRMS and 0~400 VRMS in one single signal conditioning module.
