RoHS compliant products

Features

16-bit resolution A/D converter board with 64 singled-ended and 32 differential input channels
Jumper switch can be used to set the input range for all channels at once to one of the following ranges: ±10V, 0 to 5V or 0 to 10V
High resolution (16-bit) and multiple channels (64 channels)
Input channels are isolated from the VME bus
Internal state machine automatically performs A/D conversion, so there is no burden on the CPU
Built-in pacer clock means A/D conversion can be periodically performed
Built-in 512-word FIFO
Interrupt can be issued after scanning is completed
Operates from a single +5V power supply by VME bus
LED lamp indicates A/D conversion in progress and bus access
C-language sample program provided
Device driver for VxWorks available (option)
