IP405 High Voltage Digital Output
The IP405 controls up to 40 low-side switches (open-drain MOSFETs). Operation of this module is very simple. Writing a ?0? bit to a channel data register opens the switch to turn off a field device. Similarly, writing a ?1? bit closes the switch to turn on the device. Each register can be read back to verify the value. Loopback monitoring of critical control signals is easily accomplished by reading back output states using Acromag?s IP400 Digital Input Module.
