The MAQ20 industrial data acquisition and control system is a family of DIN-rail-mounted, programmable, multi-channel, rugged signal conditioning, input/output and communication modules. They mount on industry-standard, 35-mm x 7.5-mm, gull-wing DIN rails. Each I/O module has a 1500-Vrms isolation barrier between the field-side and system-side wiring, while some models offer per-channel isolation.
