Safe, Simple and Visible Safety Controller with No Programming

• Conforms to global safety standards.

• All-in-one constructions for easy multi-input safety circuits.

• Information where you need it: LED indicators, auxiliary outputs, and serial communications.

What is Safety Controller?

Are Your Safety Inputs Connected to Your PLC Built with Interlocks?

Generally, safety is jeopardized in PLCs and other programmable control devices due to partial memory loss, CPU runaways, and situations such as on-site overwriting of programs. Using Safety Light Curtains and Safety Door Switches on their own does not necessarily ensure sufficient safety for PLC operation. Nor is safety fully secured through the use of relays in interlocks due to hazardous events that occur as a result of fused relays or short-circuited wiring.

The F3SX offers safety and simple connections for an array of safety equipment, such as Safety Light Curtains and Safety-door Switches, functioning as a central hub to perform integrated monitoring of various safety equipment.

Configuration

The Modular Configuration Fits Your Equipment Perfectly. An All-in-one Solution for Delivering Required I/O

Note

1: Up to four sets of F3SN-A/B Safety Light Curtain/F3SH Multi-beam Safety Sensors can be supplied power from the F3SX. Consider this factor when selecting and wiring the Safety Controller. Up to four Modules can be connected if the Safety Light Curtains/Multi-beam Safety Sensors are supplied power directly from an external power supply.

2. To set the delay time, use the Function Setup Software for the F3SX or specify a model with the T[][][] suffix.

Safe!

The Safety Controller Complies with Global Safety Standards

In addition to International standards (IEC), the F3SX also conforms to European (EN), and U.S./Canadian (UL) safety standards, enabling trouble-free use in machinery for Europe, the U.S. and Canada.

Applicable Standards:

• European Machinery Directive 98/37/EC, Low Voltage Directive 73/23/EEC

• IEC 61508 1998 (EN 61508 2001) (SIL 1-3)

• EN 954-1 1996 (Category B 1-4)

• EN 50178 1997, UL 508, UL 1998, etc.

Technology-backed Safety Design

We pursued safety to the limit to deliver safety and reliability backed by the highest level of safety design and FMEA. Two CPU Units perform mutual checking and diagnostic monitoring of each I/O section, and the safety of operations is further verified by FMEA and process-controlled design and production.

Simple

Connection is Easy Using Plug-in Connectors for Even More Readily Accessible Safety

• No unnecessary wiring between Units allows considerable cuts in the cost of evaluating design safety.

• Reduced wiring, post terminals, and connector connections enable substantial reductions in the cost of maintenance labor.

• Width has been reduced by 50% from 225 mm to 112.5 mm max. (compared to previous OMRON products; connecting F3SN (4 sets), F3SP-B1P, and G9SB-301).

• Post terminals aid in preventing unintentional neglect to tighten terminal screws.

• Convenient F39-TB01 Junction Box for Safety Light Curtain. Using the Connector Cables specially designed for Safety Light Curtains/Multibeam Safety Sensors and a Junction Box for Safety Light Curtain makes for efficient wiring to a Control Box installed at a distance.

Visible

Providing Meaningful Safety Equipment information that Satisfies Needs for Safety and Peace of Mind

Previously:  Majority of time lost due to failures is from investigating the causes. In particular, most time is spent in determining the location of broken lines or faulty contacts.

Using F3SX: Shorter Downtimes! Indicator displays are easy to understand and more convenient. The F3SX uses indicators to show the status of each I/O, contributing to less time (downtime) spent investigating the cause.

Application

Applications Using Electromagnetic Lock Switches and Safety Light Curtains for Detecting Workers

Simple External Stop Input Connection

When an electromagnetic lock and Safety Light Curtain (worker detection) are used, as shown in the diagram, an external stop command input is required in addition to the Emergency Stop Switch.
Inputting a PLC operation command to the SSC input allows easy connection and control. Causes of failures can be determined from detailed communications data, which safeguards against any problem that may occur.

Indicator Lighting Pattern Shows Lock Release Timing to Operator

External indicator output lighting patterns can be utilized as work permission indicators. When equipment stops, the indicator turns ON. During OFF delays, indicator flashing gradually increases speed as the remaining time shortens to notify the operator of release timing. This contributes to increased productivity and dispels agitation due to unknown waiting times.
