MAQ20 - Series

Industrial Data Acquisition & Control System

Produktfamilie MAQ20

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 (MAQ20 System Block Diagram). Each I/O module has a 1500 Vrms 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 35 x 7.5 mm gull-wing DIN rail. A backbone mounts within the rail providing power and communication interconnections between the communications modules and each I/O module.

The Modules: Compact, Flexible, and Powerful

One MAQ20 communications module can interface to up to 24 I/O modules to construct a system with a maximum of 384 channels that fits within a standard 19" instrumentation rack. Processors within each module make this distributed system extremely powerful.

  • Communications Module: Offered in Ethernet, RS-232, RS-485, and USB with host application software interfacing to the system using Modbus TCP or Modbus RTU protocol.

  • Analog Input Modules: Interface to a wide range of standard industrial sensors and equipment and offer up to 16 channels of input, each of which can be independently configured; signal ranges are user selectable and offered in differential and single-ended configurations.
  • Voltage and Current Input Modules offer 8-channel differential input or 16-channel single-ended input for precise measurement of voltage and current signals;  all channels are individually configurable for range, alarm limits, and averaging.
  • Thermocouple Input Modules offer 8 differential input channels, all of which are individually configurable for range, alarm limits, and averaging. Separate models are offered for interfacing to Type J, Type K, Type T and Types R and S thermocouples.
  • RTD and Potentiometer Input Modules interface to 2-wire, 3-wire, and 4-wire sensors including five RTD types and potentiometers. Modules offer six channels, each configurable for range, alarm limits, and averaging.
  • Strain Gage Input Module* connects to full, half, and quarter bridge sensors and offers four channels; each channel is configurable for range, alarm limits, averaging, bandwidth, excitation V, gain, shunt cal resistors, and sample rate.
  • Frequency Input Module* accepts zero-crossing and TTL signals with frequencies of DC to 1MHz and provides a DC stimulus for contact sensors. This module has eight channels, each configurable for range and alarm limits.
  • Analog Output Modules: Voltage and Current Output Modules drive valves, perform other crucial process operations, and provide up to eight channels of output which can be independently configured.

  • Discrete Input/Output Modules: Provide multiple channels of input and output per module and offer advanced special functions as well as alarm capability.

The System Backbone resides within the DIN rail used for module mounting and provides power to and interface between the communications module and the I/O modules.
