input (with daughter board DB-16P)
» Functional Description
The PCI-M512 provides 512K bytes memory and the PCI-M4M provides 4M bytes memory.
They consist of one 12-bit input port and one 16-bit output port.
The user can use the DB-16P to connect the input ports (CN2) for isolation purpose, or use DB-16R to interface to the output ports (CN1) for relay control.
