Reliably connect industrial safety controllers to sensors and actuators

20-01-2016 | Molex | Subs & Systems

To provide a reliable solution for connecting industrial safety controllers
to sensors and actuators in harsh-duty environments, Molex has introduced
the Brad HarshIO Series Ethernet modules.

Machine mountable in an IP67 rated housing, Brad HarshIO modules are ideal
for industrial applications where liquids, dust or vibration may be present,
and have been tested to withstand shock, high-vibration and high
temperatures.

The modules are designed for safety applications, up SIL3 (Safety Integrity
Level 3), Cat4/Ple, where communication over EtherNet/IP is needed to
exchange safety and standard control data and diagnostics information over a
single Ethernet network.

The compact modules offer 12 safe inputs and 4 safe outputs, supporting
connection of single and dual channel safety devices - ideal for automotive
applications running robots in cells. The digital inputs and outputs can
connect to both standard and safety rated sensors and utilises test pulses
for connected standard outputs to perform diagnostics on panel lamps,
buzzers and standard actuators. An over-moulded on-board memory key,
available internally or M8, stores the configuration allowing module
replacement in a minute without any special tools or re-commissioning.

Advanced features such as built-in 2-port Ethernet switch with DLR,
diagnostic LEDs, and a flexible IP address-setup method make configuration
and operation simple. The integrated 2-port switch with DLR can be
daisy-chained, allowing the user to wire the entire application without
switches, thus achieving cost savings. Machine space is saved with the use
of Molex M12 Ultra-Lock push-to-lock connectors allowing sensing devices or
actuators to plug directly into the I/O module, creating an IP67
environmentally sealed Ethernet connection. The HarshIO modules are compact;
the overall product dimensions being just 240mm x 62mm x 46mm.

The units are Rockwell Automation ready and are compatible with all Rockwell
GuardLogix controllers. Commissioning is made easy with Molex’s SNCT
software and Rockwell Automation’s Studio 5000 Logix Designer application.
(Note according to RA The Logix Designer application is the rebranding of
RSLogix 5000 software.) Certification and regulatory approvals for the
modules include TÜV and ODVA, conforming to EN 61508 SIL3, Cat4/Ple
according to ISO 13849-1, CE, RoHS, REACH, UL/cUL, Korean CC and China
(CCC).
