IP440A: Digital Input Module, Isolated
Please sign in or register to see model options and to add products to your cart.
Product short description:
- 32 port-isolated input channels
- ±60V AC/DC input (three ranges)
- Interrupt support for each channel
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 grouped into four 8-channel ports. Ports are isolated from the logic and each other.
Change-of-state interrupts are supported using paired channels. Debounce eliminates spurious interrupts from noise and switching transients for error-free edge detection.
Closed-loop monitoring of critical control signals is easily accomplished using the IP440A in conjunction with Acromag’s IP445 digital output module.
The IP440A is a drop-in replacement for the IP440, please see the known differences document below for more information.

Specifications
Digital Inputs
Input channel configuration: 32 optically isolated inputs.
Isolation: Logic and field connections are optically isolated. Individual ports are also isolated from each other. Input lines of individual ports share a common connection and are not isolated from each other. Logic and field lines are isolated from each other for voltages up to 250V AC rms 250V DC on a continuous basis (unit will withstand a 1500V AC dielectric strength test for one minute without breakdown).
Bipolar input voltage range: IP440A-1: ±4 to ±18V DC or AC peak; IP440A-2: ±16 to ±40V DC or AC peak; IP440A-3: ±38 to ±60V DC or AC peak.
Input low-to-high threshold: IP440A-1: ±2V typical; IP440A-2: ±6.8V typical; IP440A-3: ±13.75V typical.
Input response time: On to off: 15μS typical. Off to on: 10μS typical.
Interrupts: 32 channels configurable as below. High-to-low transitions. Low-to-high transitions. Change-of-state (two inputs required).
Debounce: Selectable for 4μS, 64μS, 1mS, or 8mS.
IP Compliance (ANSI/VITA 4)
Meets IP specifications per ANSI/VITA 4-1995.
IP data transfer cycle types supported: Input/output (IOSel*), ID read (IDSel*), Interrupt select (INTSel*).
Access times (8MHz clock): 0 wait states (250ns cycle).
Updates: Requires four 8-bit reads to update all channels.
Environmental
Operating temperature: 0 to 70°C (IP440A-1/2/3) or -40 to 85°C (IP440A-1E/2E/3E models).
Storage temperature: -55 to 150°C (all models).
Relative humidity: 5 to 95% non-condensing.
MTBF: Contact the factory.
Power: +5V (±5%): 150mA maximum,65mA typical. ±12V (±5%): 0mA (not used).
- 32 port-isolated input channels
- Three input ranges (different models):
- IP440A-1: ±4 to ±18V DC or AC peak
- IP440A-2: ±16 to ±40V DC or AC peak
- IP440A-3: ±38 to ±60V DC or AC peak
- Interrupt support for each channel
- High-speed processing (0 wait states)
- Programmable polarity of event interrupts (low-to-high or high-to-low transitions)
- Programmable debounce
- Input hysteresis
- Reverse polarity protection
- Software configuration (no jumpers or switches)
- 0 to 70°C (IP440A-1/2/3) or -40 to 85°C (IP440A-1E/2E/3E models)
- Software configuration allows “on-the-fly” changes without removing modules.
- Pins are compatible with IP445 output module for loopback monitoring
- Loopback monitoring enables self-test and fault diagnostics to detect open switches or shorts.
