PMC341 modules provide fast, high resolution, simultaneous A/D conversion of eight channels.

These modules have sixteen analog inputs which are sampled as two eight-channel banks. Eight A/D converters (ADCs) permit simultaneous conversion of all eight channels in a bank. All 16 channels share two generous 512-sample memory buffers. Conversion of each bank requires only 8µS, and all 16 channels can be sampled in just 16µs.

Flexible configuration options give you extensive control over the conversion process. The channels or bank to be converted, timing, scan mode, and other parameters are user-programmable. Interrupt support adds further control to interrupt upon a programmable threshold when the memory is full.

  • Description

    Screw terminal panels simplify field signal wiring. A cable connector provides a clean interface to the I/O board or module.

    Many termination panels have a compact footprint and mount neatly on a DIN rail strip. Other panels are designed for mounting directly onto a standard 19-inch computer rack.

    All of Acromag’s I/O boards have a corresponding termination panel. This convenience saves you the time and hassle of finding a compatible panel or crafting your own.

    For more information see modules user manual.
