Product: VRM-A2613A

The VRM-A2613A is a 6U (double height), single slot width CompactPCI bus analog input board equipped with 12-bit resolution A/D converter, 64-channel single-ended and 32-channel differential input, Input voltage range can be set to +10V, 0 to 5V or 1 to 5V for all channels at once, 0 to 20mA or 4 to 20MA current mode can be set by jumper, Analog input and digital system isolated by photo-coupler, Interrupt can be issued to the CPU after completion of A/D conversion, All channels can be scanned automatically using a software trigger, Built-in pacer clock allows continuous scanning at a constant frequency for processing, Built-in 512-word FIFO enables the storage of eight batches of data for single-ended (64-channl) input, Full Hot Swap support.
