Industry Pack Modules Industry Pack Modules IP409 Differential Digital Input/Output The IP409 provides 24 differential I/O channels with interrupts. Each channel is programmable as an input or an output on a bit basis, in any combination. All channels can generate change-of-state (COS), low, or The IP409 has 24 channels with interrupts for reliable, high-speed serial or parallel data transfer across noisy environments. high level transition interrupts. Environmental Specifications Each channel uses a robust RS485/422A transceiver that Operating temperature: 0 to 70°C (IP409) or supports bi-directional data transfer in one direction at RS485 Transceivers -40 to 85°C (IP409E).
