XYCOM XVME-505/1 (70505-001 / 71505A) VME 4-channel Analog Output Module Complete Technical File
I. Brand and Model Basic Information
Brand: XYCOM (belonging to Acromag Xembedded, an established VME industrial control hardware in the United States)
Full Model: XVME-505/1, original part code 70505-001, board printed and embossed identification 71505A
Product Form: 3U single-height VME slave board, 6U size front panel, pure voltage-type analog output card (without current loop)
Positioning: VME rack closed-loop output, paired with XVME-601/602 VME CPU master control
Life Cycle: Original factory complete discontinuation, only disassembled test pieces / a small amount of new leftover goods, core replacement spare parts for old production lines of extrusion, printing, and packaging
Core Analog Output (AO) Hardware Parameters
Channel Configuration
4 independent voltage analog output channels, electrical isolation and buffering between channels
Conversion Precision
12-bit D/A digital-to-analog conversion, full-scale accuracy ±0.05% FS, low drift controllable
Jumper selectable voltage range (single / bipolar)
0–5 V single polarity
0–10 V single polarity
±5 V bipolar
±10 V bipolar
Drive Capacity
Minimum load impedance per channel ≥ 1 kΩ; stable without voltage drop distortion with load
Calibration Structure
Board-mounted independent fine-tuning potentiometer: zero point offset, full-scale gain calibration per channel
Signal Compatibility
Native compatibility with Analog Devices 3B series signal conditioning base system
Power Supply Isolation
Board-mounted isolated DC/DC power supply, powered by VME backplane, no external auxiliary power supply required
VME Bus Interface Specifications
Bus Mode: VMEbus A16/A24 address, D08/D16 data width, standard Slave slave device
Interrupt Capability: Jumper configuration for VME IRQ0~IRQ7 interrupt levels, hardware interrupt triggered upon D/A conversion completion
Address Mapping: Board-mounted multiple sets of address jumpers, multiple XVME-505/1 can be parallel in the same rack without address conflicts
Bus Timing: Standard VME read/write timing, DTACK hardware response, compatible with XYCOM full series VME CPU motherboards
Mechanical, Interface and Electrical Power Consumption
Structural Dimensions
Circuit board 3U single-height; front panel widened to 6U height to adapt to standard 6U VME rack; standard P1 96-pin VME backplane connector
External Wiring
Front panel integrated high-density multi-pin terminal block, 4 AO signals, common shielding ground unified extraction
Power Supply: From VME backplane
+5V, ±12V standard VME power rails; typical power consumption of the entire machine 0.45A@+5V
Status Indicator Lights
Power PWR, bus BUS active dual-color LED rapid fault diagnosis
