Installation Restrictions for I/O Module Nest
Yokogawa Current/Voltage Input Module AAM11B/ZCT
|
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.
Analog I /O Module
Current/Voltage Input Modules
These modules receive 4-20 mA from 2-wire transmitters and 1-5 V
standardized signals. They can also
receive signals other than standard 4-20 mA or
1-5 V signals. AAM11B/ZCT can be combined with a transmitter
which supports BRAIN communications. Use
our BRAIN terminal to specify parameters for a transmitter. Yokogawa Current/Voltage Input Module AAM11B/ZCT

*1: This module can be combined with MTL barrier 728. In this case, wiring resistance must be 10 Ω or less and the minimum operating voltage of the 2-wire transmitter must be 12 V DC or less.
*2: When the power of AAM11B/ZCT is OFF or an abnormal condition occurs, the current input loop is open.
Do not share current
signals with other receivers. To share signal, attach Shunt Resistance (250 Ω) to current-output module and share voltage output.
