Yaskawa Remote Analog I/O PCB for use with Microtrac DSD LAN - Manual

INTRODUCTION
The Remote Analog I/O [Input/
Output] PCB (ANIO) adds I/O capability to a
Remote I/O [Input/Output] Controller LAN
Node PCB (RIO) in a MicroTrac DSD system.
The ANIO is connected to the RIO through
use of an I/O expansion bus. Upon power
up, the RIO will realize that the ANIO is
present, and begin utilizing the added I/O.
This document explains the
hardware of the Remote Analog I/O PCB
(ANIO) and how to utilize its I/O capability.
HARDWARE DESCRIPTION
POWER REQUIREMENTS
The power connector on the RIO is
used to supply the RIO and the Remote I/O
PCBs with power. The RIO supplies power
to each of the Remote I/O PCBs through
the I/O expansion bus. The power
requirements for each of the voltages
connected to the RIO, therefore, include the
power drawn by the RIO and the power
drawn by each of the Remote I/O PCBs.
In order to select a properly sized
power supply, the current (I) requirements of
the PCBs for each of the voltages must be
known. The I requirements for the ANIO are
as follows:
I for +5 VDC = (I of ANIO) + (I of external
loads)
= (923 mA) + (I of external
loads)
I for +15 VDC = (I of ANIO) + (I of external
loads)
= (82 mA) + (I of external
loads)
I for -15 VDC = (I of ANIO) + (I of external
loads)
= (95 mA) + (I of external
loads)
I for +24 VDC = (I of ANIO) + (I of external
loads)
= (0 mA) + (I of external
loads)
