MAQ20-IDN is an 8-channel differential input analog module designed for precise measurement of 0-20mA and 4-20mA current signals in industrial and test applications. Each channel is individually configurable for range, alarm limits, and averaging, with hardware low-pass filtering to reject 50Hz and 60Hz line frequencies. Input-to-bus isolation is 1500Vrms, and each channel is protected against continuous 240Vrms overload. The module supports selective channel enabling to increase scan rate, with a maximum scan rate of 200 channels per second. It features a pluggable terminal block with shield termination positions and operates within a temperature range of -40°C to +85°C. Dimensions are 114.6mm x 15.3mm x 82.8mm. The module is Heavy Industrial CE compliant and certified for Class I, Division 2, Groups A, B, C, D hazardous locations under UL/cUL File E232858.
MAQ20 voltage and current analog input modules interface to a wide range of volt, millivolt, and milliamp sensors and equipment used in industrial and test and measurement applications. They 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 to match the most demanding applications. High, Low, High-High and Low-Low alarms provide essential monitoring and warning functions to ensure optimum process flow and fail-safe operation. Hardware low-pass filtering in each channel provides rejection of 50 and 60Hz line frequencies. Field I/O connections are made through a pluggable terminal block with four positions provided for the termination of wiring shields.
Input-to-bus isolation is a robust 1500Vrms and each individual channel is protected up to 240Vrms continuous overload in case of inadvertent wiring errors. Overloaded channels do not adversely affect other channels in the module, thereby preserving data integrity.
Channels in a module can be selectively enabled for scanning. All channels are enabled by default; however, non-used channels can be disabled to increase the sampling rate of enabled channels.
Input ranges are selectable on a per-channel basis. The MAQ20-MVDN, -VDN, and -VSN modules have five user selectable input ranges; the MAQ20- IDN and -ISN modules have two. Over-range and under-range up to 2% beyond the specified input values is allowed, and accuracy is guaranteed to ±f.s.
Cables to interface 8B backpanels to the MAQ20-VSN module are available; the 8B modules and backpanel assembly provide 1500Vrms channel-tochannel isolation.
