QMC mezzanine modules plug into a carrier card to interface connected I/O and provide a variety of signal processing functions. Acromag QMC450 modules offer 32 isolated solid-state relay outputs to safely control discrete level devices. A PCIe bus interface provides communication to the carrier and host computer.
Isolation protects your computer system from noise, transient signals, and field wiring faults. The outputs are grouped into four 8-channel ports. Ports are isolated from the logic and each other.
A major QMC450 advantage is its flexibility. The module supports wide-range, bipolar, AC or DC voltage switching. Each port is configurable for high or low-side switches.
Readback buffers simplify output status monitoring. And for easy closed-loop monitoring of critical control signals, use the QMC450 in conjunction with Acromag’s QMC440 digital input module.
QMC modules adhere to the VITA 93 standard for small form factor (SFF) mezzanine modules. Two high-performance 80-pin connectors provide separate field I/O and PCIe bus host interfaces. Modules can deploy on a variety of carrier card platforms including PCIe expansion cards, 3U/6U Eurocards such as VPX and CompactPCI, VNX+ SFF cards, and many other architectures. The rugged design is well-suited for use in laboratory, industrial, defense, and aerospace applications.
QMC modules have a much smaller footprint than PMC/XMC modules. Single-width QMC modules are only 26 x 78.25mm which facilitates mixing and matching of multiple functions on a single carrier card for high-density I/O solutions. They are ideal for computing systems with strict size, weight, power, and cost (SWAP-C) limitations.
An Intelligent Platform Management Interface (IPMI) facilitates system management. The QMC EEPROM holds module information and sensor data that is accessible by a smart carrier card with an IPMC controller over an I2C interface
