IDEC Corporation is introducing the FS1B Safety Controller, an enhanced version of the well-received FS1A model, offering more features. The FS1B allows designers to develop efficient machine safety systems featuring various safety channels by utilizing any of the 24 pre-configured safety logic strategies chosen through DIP switch settings—eliminating the need for programming.
Replacing individual modules
Typical safety circuit configurations frequently utilize numerous safety relays to handle several inputs from emergency stop (E-stop) buttons, light barriers, and various safety devices to deliver a safety interlocking output for shutting down related equipment. The FS1B integrates this functionality into a small, independent design, featuring handy and dependable push-in terminals.
DIP switches along with a single “enter” button allow for swift and simple configuration of the safety logic strategy, inputs, and power off delay timer, and these configurations can be secured with a protective cover fastened by a labeled cable tie to avoid unintended modifications. Colored LEDs and seven-segment digital displays offer a clear view of device and input/output status at a glance.
The FS1B features 12 universal discrete inputs that can be assigned to a maximum of 6 safety channels. For safety devices, the default setting can utilize each dual-channel input pair, or it can be modified to: direct opening input, dependent input, NO/NC input, or safety input II—each option may include or exclude synchronization monitoring. Alternatively, separate inputs may be configured to track non-safety devices, like reset or other external signals, within the logic framework. Four safety outputs enable the capability to shut down various equipment or systems.
Simple safety setup
Other safety products may require multiple devices, configuration software and programming, drivers, and then additional program certification. The FS1B overcomes these shortcomings with 24 built-in safety logic strategies, each of which are certified on this device by a trusted independent body to ensure proper and reliable performance. This pre-certification enhances system safety, simplifies the design process, and streamlines the overall approval process for machinery certification.
Some examples of typical safety logic strategy options include partial stop, mode switching, switch/sensor combined, OR logic, and two-handed logic control. A web-based online simulator allows users to quickly select their application requirements, determine the best configuration, and obtain a circuit diagram output to document the settings.
The FS1B carries applicable IEC 61508, ISO 13849, UL508, and other approvals. Depending on the application, the safety performance can be up to SIL 3, PLe, Category 4. Powered by industry standard 24V DC, with a wide operating temperature range of -10 to +55 Deg C, and robust vibration resistance, the FS1B will excel in most any control panel location, whether on-board or external to the protected equipment.
Flexible safety for a multitude of applications
Whether for small-scale systems and production processes, or as part of a larger safety control system, the FS1B streamlines designs while improving safety. Typical industries and machines/equipment with these needs include injection molding, semiconductor manufacturing, metalworking, pharmaceuticals, food processing and packaging, robotics, automated guided vehicles (AGVs), autonomous mobile robots (AMRs), and others.
Of special interest for OEMs or other designers of equipment with multiple options or configurations, the FS1B can be designed into the controls once, and then adjusted with the safety logic strategy to adapt for various types of inputs. This allows for a standardized design supporting flexible equipment options, minimizing development effort, while simplifying stocking and control panel fabrication.
