Installation Restrictions for I/O Module Nest
Yokogawa Small Electric Power Input Module AAM21
|
Model AMN12 High-speed Nest for Analog I/O Modules (*1)
-Always install in Nest No. 1.
-Do not install any I/O module nests in Nests No. 2 through No. 4.
-When using non-AMN12 I/O Module Nest with AMN12, always install it in Nest No. 5
Model AMM22T, AMM22TJ (*2)
-Do not install non-AMM22T, AMM22TJ I/O module
below AMM22T, AMM22TJ because AMM22T, AMM22TJ is a module for thermocouple entry. If there were a heat source below AMM22T, AMM22TJ, a reference junction compensation
error occur.
-If there is another module (heat source) below AMM22T, AMM22TJ when using 19” Rack Mountable Type,
a thermal shield must be inserted between AMM22T, AMM22TJ
and the heat source (See Figures 6 and 7).
Model AMN51 Nest for Communication Cards (*3)
-Only
one nest is installable in PFCS/PFCD.
Its position is fixed as Nest No. 2.
AMN52 Nest for PROFIBUS Communication Module
-Only one nest is installable in PFC￡. Its position is fixed as Nests No. 1 and 2. AMN52 cannot be combined with AMN51.
Small Electric Power Input Module
This
module receives signals from mV,
thermocouple, RTD and potentiometer.
