egnite: CMI8848 1.0 Rev-B

CMI8848 expands the capability of the Ethernut boards by providing 8 galvanically isolated digital I/O channels, available at pluggable spring-cage terminal blocks. In combination with an Ethernut board, AC and DC loads and states can be remotely monitored and controlled over a TCP/IP network. The boards are stackable, 2 CMI8848 boards are supported by a single Ethernut board.
8 optocoupler inputs are individually jumper configurable to sense dry contacts or voltages between 3.3 V and 48 V. 8 solid state relay outputs can directly drive high loads like contactors, actuators or motors. All optocouplers and relays are mounted in sockets and may be replaced by pin-compatible components.
CMI8848 is compatible with Ethernut 1, 2, 3 and 5.
