The ACTIS Computer ADA-08 is a single-size IndustryPack module that integrates data acquisition, analog signal conditioning, and digital I/O into one VITA-4 compliant form factor. It combines three functional blocks: a counter/timer and parallel I/O unit, an octal 12-bit DAC with eight buffered outputs, and a 12-bit plus sign ADC with eight single-ended or four differential inputs. All signals operate at TTL levels, making integration with legacy and modern control systems straightforward.
Technical Specifications

– Key Features
Eight independent DAC channels eliminate the need for external buffering in most applications. The ADC’s on-chip sequence RAM reduces firmware overhead by enabling autonomous multi-channel acquisition. The flexible counter/timer block supports external event counting, PWM generation, and interval measurement simultaneously.
– Typical Applications
Process control systems, data logging platforms, real-time sensor interfaces, industrial test stands, and embedded instrumentation requiring synchronized analog and digital I/O.
– Compatibility & Integration
Designed for VITA-4 standard IndustryPack carrier boards such as the VIPC-6400B 6U Quad IP module carrier (rated for 16-bit @ 8 MHz VITA-4 modules). All interconnects and signal standards follow VITA-4 specifications.
