Industry Pack Modules IP440-x Isolated Digital Input IP440 Industrial I/O Pack (IP) modules provide 32 optically isolated inputs to safely monitor a wide range of digital input voltage levels. Isolation protects your computer system from noise, transient signals, and field wiring faults. The inputs are When used together, the IP440 input module and IP445 output module simplify loop-back monitoring of your critical signals. grouped into four 8-channel ports. Ports are isolated from the logic and each other. Environmental Specifications Operating temperature: 0 to 70°C (IP440-1/2/3) Change-of-state interrupts are supported using Digital Inputs or -40 to 85°C (IP440-1E/2E/3E models). Input channel configuration: 32 optically isolated inputs. paired channels. Debounce eliminates spurious Storage temperature: -55 to 125°C (all models). interrupts from noise and switching transients for Isolation: Logic and field connections are optically Relative humidity: 5 to 95% non-condensing. isolated. Individual ports are also isolated from each other. error-free edge detection. MTBF: 336,846 hrs at 25°C, MIL-HDBK-217F, Notice 2. Input lines of individual ports share a common connection Closed-loop monitoring of critical control signals is and are not isolated from each other. Logic and field lines Power: are isolated from each other for voltages up to 250V AC or +5V (±5%): 160mA maximum. easily accomplished using the IP440 in conjunction 354V DC on a continuous basis (unit will withstand a ±12V (±5%): 0mA (not used). with Acromag’s IP445 digital output module. 1500V AC dielectric strength test for one minute without breakdown).
