Ioem And Rem Features - Xylem YSI IOEM Safety And Installation Manual

Introduction
Thank you for purchasing a YSI IOEM and/or REM Expansion Module(s). The
IOEM-4, IOEM-8 and REM are networkable instruments that communicate with
YSI 5X00 family of programmable aquatic control and alarming instruments. (The
YSI 5X00 family of instruments include 5200A, 5400, 5500D-01, 5500D-02 and
5500D-04 instruments.) IOEM and REM expansion modules provide additional
inputs and outputs for 5X00 instruments existing on an RS485 network. Peripheral
devices wired and configured to IOEM and REM expansion modules add flexibility
and capability to a network. Configure IOEM and REM expansion modules as
needed for your application.
IOEM and REM instruments do not have a user interface, meaning no configura-
tion can be done at the instrument. Use AquaManager® PC software program to
configure IOEM and REM instruments.
Please see IOEM/REM terminology - page 71 for terms used throughout this
manual in describing IOEM/REM nstrument features and functionality.

IOEM and REM features

IOEM and REM expansion modules share many common features. The common
features are listed below. (IOEM & REM unique features are provided following
the common features listed below.)
A 5X00 instrument is required and must be configured as the master on the
RS485 network;
•
NEMA-4X / IP65 enclosure;
•
universal AC power;
•
optional DC 12 VDC power, including battery backup;
•
*AquaManager® PC software is required and serves as a management
tool using either a direct (RS232) or TCP/IP connection where a 5X00
instrument is configured as a master on the RS485 network;
•
1 32-bit processor;
• networking capability - With a 5X00 instrument configured as the master,
an additional 31 slave IOEM, REM and/or 5X00 instruments can be added
to the network. The network uses RS485 protocol;
• field upgradable firmware, including RS232 port for firmware updating;
•
power and communication status LEDs see Troubleshooting; Status
LED, page 85.

*AquaManager adds the ability to:
•
configure IOEM and REM channels to 5X00 networked instruments;
•
configure, graph and map IOEM systems and REM channels;
•
log and view IOEM channel system data and REM events;
In addition to the common features listed above, IOEM functionality includes:
• 4 (IOEM-4) or 8 (IOEM-8) 8 selectable I/Os; I/Os can be configured
as digital, analog (0-1VDC, 0-5VDC, 4-20/mA) or temperature inputs;
• 4 (IOEM-4) or 8 (IOEM8) selectable I/Os can be configured as 5X00
instrument system 4/20mA outputs;
In addition to the common features listed above, REM features include:
•
four (4) onboard output relays rated at 250VAC@10AMPs;
See IOEM and REM Product Specifications, starting on page 12, for complete
instrument specifications.
Use of this equipment for something other than the intended use of the instru-
ment is prohibited.
Figure 1.1 shows an REM front panel and enclosure. (IOEM front panel and
enclosure are identical.) Compression fittings located on the bottom of the en-
closure provide liquid-tight connections for wiring peripheral devices and IOEM
and REM devices and components.
