Industry Pack Modules Industry Pack Modules IP440A-x Isolated Digital Input IP440A 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 IP440A 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 (IP440A-1/2/3) Change-of-state interrupts are supported using Digital Inputs or -40 to 85°C (IP440A-1E/2E/3E models). Input channel configuration: 32 optically isolated inputs. paired channels. Debounce eliminates spurious Storage temperature: -55 to 150°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: Contact the factory. 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 rms +5V (±5%): 150mA maximum, 65mA typical. easily accomplished using the IP440A in conjunction 250V 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).
