There are modules and systems with 2 and/or 3 amplifier units especially for applications with a few channels and stand-alone operation. The compact modules have non-removable amplifiers, with the miniature systems in 19” technology they are exchangeable. Besides the proven modular 4-channel amplifiers for strain gauge, temperature, ICP® sensors, voltage, current, frequency signals (2 channels), and Digital-IO there is now a 2-channel universal amplifier available.
All modules and systems are designed for DC supply (9 - 36 V) or AC supply (110 - 230 V), and have a CAN interface. Parameters can be set via a serial (RS 232 / RS 485) interface on the back or a CAN adapter. Signal input is from the front side. The miniature systems also offer an Ethernet interface for data acquisition and parameter setting.
