Versalogic VCM-DAS-3 - Analog Output & Digital I/O Module for the PC/104 Bus
Once you accept your quote and confirm your order, we prepare by retrieving related parts and components from our inventory. Anything we do not currently have in stock is sourced.
Upon receipt, all parts are visually inspected for damage and then photographed to document their condition. Parts acquired from vendors must meet our quality standards.
Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.
Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.
Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.
Industrial computer boards have all I/O connections rigorously tested to ensure that everything is working properly before the board is certified as ready to ship.
After photos are taken to document the exterior condition of the part, it is packaged and sent to the customer. ESD-safe materials are used to protect sensitive equipment on its journey.
Industrial Trading is a website of GID Industrial, an ISO 9001:2015-certified company that has specialized in servicing industrial computer boards and providing other industrial products for sectors including manufacturing, defense, aerospace, entertainment, healthcare, and more by utilizing our combined skills and vast international network of trusted suppliers since our founding in 2015.

VCM-DAS-3 Analog Output + Digital I/O Module 16 channel analog output with 12-bit resolution 24 channel digital I/O Extended temperature operation RoHS compliant Highlights Overview The VCM-DAS-3 I/O module provides 16 channels of 12-bit resolution analog outputs along Analog Output with 24 digital I/O lines on a single PC/104 module. The rugged VCM-DAS-3 is designed 16 analog outputs with 12-bit resolution. to provide capabilities beyond what is presently available on the market while maintaining Multiple Output Ranges drop-in compatibility with current industry standards. Ideal applications include process Configure output ranges via software or with on-board jumpers. control, closed-loop servo control, and motor-control. DAC Update Update outputs individually or simultaneously. Details Dual ISA Modes The versatile VCM-DAS-3 I/O module has four LTC2704 quad 12-bit D/A converter chips Enhanced 16-bit ISA functionality is provided while retaining 8-bit compatibility. which provide sixteen 12-bit analog output channels. All output ranges can be configured independently via software or in groups of eight by jumpers. Both unipolar and bipolar mode Read-back Function are fully supported by this module. All analog output channels can be updated individually Read-back of DAC and SPAN codes for simplified programming or simultaneously, either with a software command or in response to an external trigger. and setup. The analog outputs can source or sink up to 5mA each. All outputs can be configured Configurable Reset to reset to either zero scale or mid-scale on power-up. To facilitate programming and Configure outputs to reset to zero or mid-scale on power-up. simplify setup, read-back functionality is provided. Enhanced 16-bit ISA functionality is Digital I/O also provided while retaining 8-bit compatibility. 24-channels of CMOS/TTL compatible digital I/O. An 82C55 compatible chip provides 24 lines of CMOS/TTL compatible digital I/O which RoHS Compliant power-up in input mode. Pull-up resistors provide known logic levels during startup.
