The MAQ20-VSN is a 16-channel single-ended analog input module designed for precise measurement of voltage signals in industrial and test applications. It features per-channel configurability for input range, alarm limits, and averaging, with five selectable input ranges: ±5V, ±10V, ±20V, ±40V, and ±60V. Each channel provides 1500Vrms isolation from the bus and is protected against continuous 240Vrms overloads. Input signals are filtered to reject 50Hz and 60Hz line frequencies, and channels can be selectively enabled to increase scan rate. The module operates with a scan rate of 200 channels per second, has an accuracy of ±0.035% of span, and a resolution of 0.012% of span. It is housed in a case measuring 114.6mm x 15.3mm x 82.8mm and is certified as Heavy Industrial CE compliant with UL/cUL Class I, Division 2, Groups A, B, C, D certification. Operating temperature ranges from -40°C to +85°C.
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.
