This chapter provides information on plug-in connector blocks and
field wiring (ANIN and PRT signals) for the I/O, Prover, and HART
modules. This chapter also discussed the optional pulse-counting
mezzanine module (P148) which fits as a daughterboard on either the
I/O or Prover module.
Caution
Failure to exercise proper electrostatic discharge precautions (such as
wearing a grounded wrist strap) when accessing the back of the unit or
when handling CPU or I/O modules may reset the processor or damage
electronic components, resulting in interrupted operations
Perform all wiring with stranded wire no larger than 1.75mm
2
. Observe
all local wiring practices and regulations.
Caution
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+.
4.1 I/O Module (P144)
The I/O module (P144) measures process signals the CPU uses while
running the flow computer functions. The module provides 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 I/O module terminations.
