This is a user manual for EDP-AM-DIO54 Digital IO Module, which introduces the module's digital outputs, using multiple digital IO modules, software drivers and more.
The EDP-AM-DIO54 is a digital I/O module designed for the RS EDP system. It features 12 input channels with overvoltage protection and optional pull-ups, plus 16 additional TTL inputs accessible via I2C. The module provides 16 high-current outputs (up to 500mA or 1A) suitable for driving relays and solenoids, along with another 16 logic-level outputs.
| Input Channels (Protected) | 12 channels with overvoltage protection and optional pull-ups |
|---|---|
| I2C Inputs | 16 TTL inputs accessible only via I2C |
| High-Current Outputs | 16 outputs with a current drive capability of 500mA |
| Logic Outputs | 16, 25mA logic outputs |
| Max Output Current (DO0-DO11) | 1A (sink) |
Up to 3 Digital IO Modules may be fitted to a single baseboard, or 4 if no CPU is fitted.
The module uses the NXP PCA9555 device.
