Digital Input/Output Module, Differential I/O
|
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
high level transition interrupts.
Each channel uses a robust RS485/422A transceiver that
supports bi-directional data transfer in one direction at
a time (half-duplex). Differential data transmission
enables reliable, high speed communication across
distances of up to 4000 feet, even through noisy environments.
Differential transmission nullifies the effects
of ground shifts and noise signals which appear as
common-mode voltages on the line.
Features
- 24 digital input and/or output channels
- Output channels support readback monitoring
- Socketed termination resistors
- Ruggedized RS422A/485 transceivers
- Interrupt support on all channels
- change-of-state
- high or low level transition
- Positive and negative current limiting
- Parallel I/O for up to 24 bits
- All channels programmable as inputs or outputs.
- Differential data transmission is ideal for high-speed, long distance communication in noisy environments.
