The MAQ®20 Industrial Data Acquisition and Control System encompasses more than 25 years of design excellence and quality in the industrial test and measurement and control industry. This powerful, high performance, highly flexible system offers the industry's lowest cost per channel, integral PID loop control, and ±0.035% system accuracy (module dependent). It is ideal for test and measurement, factory and process automation, machine automation, military and aerospace, power and energy, environmental monitoring, and oil and gas applications. The MAQ20 family consists of DIN rail mounted, programmable, multi-channel, industrially rugged signal conditioning input and output modules and communications modules (Figure 1). Each I/O module has a 1500Vrms isolation barrier between field-side and system-side wiring, and many models offer per-channel isolation. All field wiring terminals are heavily protected against overload, accidental connection of incorrect signals, and ESD. Modules mount on the industry standard 35x7.5mm gull-wing DIN rail. A backbone mounts within the rail providing power and communication interconnections between the communications modules and each I/O module.
