Management, Monitoring and Control of High-Value
Distributed I/O Assets
The monitoring and protection of high-value
distributed I/O assets involves more than simple access to
its data, it also involves the protection and control of
its physical environment along with the ability to take corrective
action when necessary. Digital and analog sensors, proximity
and mechanical switches, relays, pushbuttons, temperature
and humidity sensors can assist in determining the integrity
of the asset’s local environment. Information
from these sent back to a central support location over a
network can help an enterprise react more quickly to an important
event or failure. IOLAN DS I/O Device Servers are ideal for
these applications.
Access I/O Devices over Ethernet using Popular Central
Applications
An IOLAN I/O Device Server is ideal for remote
I/O management using common
SCADA or OPC Servers using Modbus/TCP protocol as well as Network Management
Systems ( NMS) utilizing SNMP.
Flexible and Reliable COM/TTY Access to Ethernet
I/O
An IOLAN I/O Device Server is ideal
for connecting COM/TTY based applications such as Modbus
ASCII/RTU to remote
I/O devices. Perle’s TruePort
re-director provides COM port or fixed
TTY connections across an IP network.
An Application Program Interface ( API ) is also available
so that custom applications can be developed to access distributed
I/O channels attached to remote
IOLAN I/O Device Servers. Common serial applications such
as Visual Basic can be used to send IOLAN API commands to
remote IOLAN I/O Device Servers across an IP network. This
API is available for the most popular operating systems today.
Universal I/O
The IOLAN DS I/O device server connects to a wide variety
of distributed I/O devices.

Universal I/O on IOLAN I/O Device Servers provides
flexibility when used across a wide array of environments.
Individual digital channels can be configured as either
inputs or outputs. Analog Inputs can support a broad range
of voltage or current type devices including industrial
grade temperature sensors such as thermocouples and RTDs.
Models with integated solid state relays can be used to
control remote contact closures.
Automated response to alarm conditions
IOLAN DS I/O Device Servers have the capability of measuring
input conditions and intelligently alerting enterprise resources
such as central TCP/IP based applications, Syslog or SNMP.
By instantly generating alerts when pre-defined threshold
levels have been exceeded, alarm notifications can be passed
along when needed. This eliminates the packet based overheads
associated with polled environments.
Rugged Industrial-Grade Design
Compact and protective metal enclosure for wall mount or
DIN rail mounting environments. Industrial grade unit protection
is provided though optical isolation of I/O channels of
2000 Vrms, Ethernet isolation of 1500 Vrms, open/short
detection logic on RTD/Thermocouple inputs and 15,000 volts
electrostatic discharge protection across all serial pins.
Advanced IP Technology
With support for Next Generation IP (IPv6) the IOLAN range
provides organizations with investment protection to meet
this rapidly growing standard. 
Lifetime Warranty
The Perle
IOLAN DS is backed by the best service and support in the
industry including Perle’s unique lifetime warranty.
Since 1976 Perle has been providing its customers with networking
products that have the highest levels of performance, flexibility
and quality.
