ICP DAS PET-7284 PoE Ethernet I/O module with counter inputs

The ICP DAS PET-7284 is a PoE Ethernet I/O module with 32-bit high-speed counter/frequency/encoder inputs and a 4-channel digital output module.

The product offers a variety of input mode options, including Up Counter, Frequency Input, Up/Down Counter, Direct/Pulse Counter and A/B Phase Counter. The modes can be individually configured for all eight channels, where, for example, some channels can be set to Up Counter mode and other channels can be individually set to Frequency, Up/ Down Counter or Encoder input mode. The built-in programmable low pass filter can be used to eliminate noise where the width of the high/low pulse is narrower than the minimum high/low width of the low pass filter.

The module is equipped with FRAM memory to retain the counter values. FRAM is a type of non-volatile memory that can be used to store written data, even after the module has been powered off. This storage feature can be either enabled or disabled, and the data can be retained for up to 10 years.

It also has a 2-port Ethernet switch for daisy-chain topologies and a built-in web HMI, as well as support for both Modbus TCP and Modbus UDP protocols.
