Description

The VCM-DAS-3 I/O module provides 16 channels of 12-bit resolution analog outputs along with 24 digital I/O lines on a single PC/104 module. The rugged VCM-DAS-3 is designed to provide capabilities beyond what is presently available on the market while maintaining drop-in compatibility with current industry standards. Ideal applications include process control, closed-loop servo control, and motor-control.

Details

The versatile VCM-DAS-3 I/O module has four LTC2704 quad 12-bit D/A converter chips 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 are fully supported by this module. All analog output channels can be updated individually or simultaneously, either with a software command or in response to an external trigger. The analog outputs can source or sink up to 5mA each. All outputs can be configured to reset to either zero scale or mid-scale on power-up. To facilitate programming and simplify setup, read-back functionality is provided. Enhanced 16-bit ISA functionality is also provided while retaining 8-bit compatibility.

An 82C55 compatible chip provides 24 lines of CMOS/TTL compatible digital I/O which power-up in input mode. Pull-up resistors provide known logic levels during startup.

The VCM-DAS-3 is designed and tested for extended temperature operation (-40° to +85°C) and is fully RoHS-compliant. It requires only +5VDC from the system power supply via the PC/104 bus. I/O connections can be made with either a 2mm latching connector or a 50-pin shrouded header for 0.1” legacy connectors.

VersaLogic exists to exceed customers' product, service, support and delivery needs - whenever the need arises.
