Digital Link Coupler

This bus coupler connects the Slice I/O system to the PiCPro® network over the Digital Link communications network. It mounts to a 35mm DIN rail and connects to up to 32 slices with up to 256 digital inputs, 256 digital outputs, 16 analog inputs and 16 analog outputs. The coupler itself includes 16 fast inputs (24 VDC), and 16 fast outputs (24 VDC).
