Introduction
The ICRL-U-8RJ45-DIN and ICRL-U8RJ45-DIN-NT switches are 8-port
Fast Ethernet industrial switch featuring a 2.0Gbps Packet Switch engine
with packet forwarding and filtering mechanisms to meet industrial
communications standards. It provides packet forwarding capabilities
to handle 64 to 1522 byte sizes in two priority queues to optimize data
forwarding performance. Broadcast storm filtering and flow control
functions ensure data delivery free of traffic congestion.
For installation in hazardous or industrial environments, the switches are
equipped with two redundant power inputs, feature wide input voltage
ranges, and operates within a broad temperature range. For ease-of-
maintenance, the switches have one alarm relay for port link and power
events to assist engineers with on-site notifications.
The ICRL-U-8RJ45-DIN provides an extended temperature range and
C1D2 certification. The ICRL-U-8RJ45-DIN-NT provides a normal
temperature range.
ICRL-U-8RJ45-DIN Only In CID2 Environments
The ICRL-U-8RJ45-DIN is open-type and is to be installed in an
enclosure suitable for the environment and only accessible with a tool.
The switch is suitable for use in Class I, Division 2, Groups A, B, C, and
D or non-hazardous locations only.
WARNING - EXPLOSION HAZARD – Substitution of any components in
the ICRL-U-8RJ45-DIN may impair suitability for Class I, Division 2.
Wiring the Power Inputs
The switch provides redundant power, reverse polarity protection and
accepts a positive or negative power source. If using redundant power
supplies, they must be in the same mode.
Use this procedure to wire the power:
1.
Insert the positive and negative wires into the + and - contacts on
the PW1 or PW2 on the terminal block connector.
2.
Tighten the wire-clamp screws to prevent the wires from being
loosened.
