CAN Analog Inputs Module (P325)

CAN Analog Inputs Module (P325)

The CAN Analog Input Module allows the PCI 208 

Motion Coordinator

 to be 

expanded with banks of 8 analog input channels. Up to 4 x P325 Modules may be 
connected allowing up to 32 x 12 bit analog channels in addition to the 4 poten-
tial analog inputs if the P184 is fitted. Convenient disconnect terminals are used 
for the I/O connections.   The input channels are designed for +/-10volt opera-
tion. Each bank of 8 channels is opto-isolated from the CAN bus.

I/O Connections

The CAN Analog Input Module has 3 disconnect terminal connectors:
