PMC Modules PMC440-x Isolated Digital Input PMC440 modules provide 32 optically isolated inputs to safely monitor a wide range of digital input voltage lev- els. A unique two-piece board design brings the proven reliability of Acromag’s Industry Pack (IP) modules to a PMC format. An IP440 module is embedded on a PMC The PMC440 safely isolates your input signals to protect your control system from harmful transients and surges. interface card that maintains maximum performance and transparent communication to the host. PMC Module Read Cycle: 1000nS typical measured from Specifications falling edge of FRAME# to falling edge of TRDY# providing Isolation protects your computer system from noise, Digital Inputs valid data. transient signals, and field wiring faults. The inputs are Input channel configuration: 32 optically isolated inputs. grouped into four 8-channel ports. Ports are isolated Environmental Isolation: Logic and field connections are optically isolated. from the logic and each other. Operating temp.: 0 to 70°C or -40 to 85°C (E version). Individual ports are also isolated from each other. Input lines of individual ports share a common connection and Storage temperature: -55 to 105°C. Change-of-state interrupts are supported using paired are not isolated from each other. Logic and field lines are Relative humidity: 5 to 95% non-condensing. channels.
