The SCM5B49 Voltage Output Module from Dataforth Corporation is designed to provide a single channel of analog output with a flexible track-and-hold circuit. This module can operate in either track mode, where one DAC serves multiple output modules, or hold mode, where each module is dedicated to a single DAC. It features signal buffering, isolation, filtering, and conversion to high-level voltage outputs ranging from ¬±5V to ¬±10V, with an input voltage tolerance of up to ¬±36V without damage. The module offers 1500Vrms transformer isolation, ensuring complete electrical isolation between the input and output, which helps in reducing ground loops and protecting user equipment from high voltage transients. It has a high common-mode rejection ratio (CMR) of 110dB and a bandwidth of 400Hz, making it suitable for applications in noisy environments. The SCM5B49 also boasts an accuracy of ¬±0.03% and linearity of ¬±0.015%, ensuring reliable performance in various industrial applications, including process control and test measurement. The module operates on a +5VDC power supply and has a compact design with dimensions of 2.28,Äù x 2.26,Äù x 0.60,Äù. It is compliant with RoHS III and certified for CSA C/US, CE, and ATEX standards, making it a robust choice for engineers seeking reliable analog signal conditioning and isolation solutions.
Each SCM5B49 voltage output module provides a single channel of analog output. The track-and-hold circuit in the input stage can be operated in a hold mode where one DAC can supply many output modules, or a track mode where one DAC is dedicated to each module. In addition to the track-and-hold circuit, each module provides signal buffering, isolation, filtering, and conversion to a high-level voltage output.
Setting of the track or hold mode is controlled by the logic state of WR EN\, module pin 23. When pin 23 is low, the track mode is enabled. If pin 23 is high, the hold mode is enabled. The module is designed with a completely isolated computer side circuit which can be floated to ±50V from Power Common, pin 16. This complete isolation means that no connection is required between I/O Common and Power Common for proper operation of the track and hold circuit. For a low state, simply connect pin 23, the Write-Enable pin, to I/O Common, pin 19.
The SCMPB02 and SCMPB06 backpanels allow host computer control of the WR EN\ control line, which allows multiplexing of one host DAC to up to 64 SCM5B49 output modules.
