Perform all wiring with stranded wire no larger than 1.75mm
all local wiring practices and regulations.
Do not use a Mega or similar instrument to check for isolation or
continuity between signals on any of the S600 connectors. These
instruments produce voltages far in excess of design parameters and
may damage the S600.
The P144 I/O board measures process signals the CPU uses while
running the flow computer functions. The I/O board is comprised of 12
analogue inputs (AI) , 4 analogue outputs (AO), 16 digital inputs (DI) ,
12 digital outputs (DO), 4 pulse inputs (PI), 5 pulse outputs (PO), 3
frequency (density) inputs, and 3 PRT/RTD inputs. Refer to Figure 4-2
for the P144 I/O board terminations.
For field wiring, the S600 backplate provides three low-density D-type
connectors labeled SKT-A, SKT-B, and SKT-C (refer to Figure 4-1).
