IDEC FS1B safety controller

IDEC Corporation is launching the FS1B safety controller, an upgrade of the FS1A device providing additional features. The FS1B lets designers create streamlined machine safety systems with multiple safety channels by using any of 24 preset safety logic strategies selected with DIP switch configuration and no programming required.

Standard safety circuit designs often use many safety relays to accommodate multiple inputs from E-stop buttons, light curtains and other safety devices. The FS1B consolidates this functionality into a compact, standalone form factor, with convenient and reliable push-in terminals.

DIP switches and a single ‘enter’ pushbutton provide quick and easy setting of the safety logic strategy, inputs and power off delay timer, and these settings can be locked in with a protective cover secured by a marked cable tie to prevent accidental changes. Coloured LEDs and 7-segment numeric displays provide clear at-a-glance device and I/O status.

The FS1B includes 12 universal discrete inputs assignable as up to six safety channels. Each of the 24 built-in safety logic strategies are certified by a trusted independent body to streamline the overall approval process for machinery certification.

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 24 VDC, with a wide operating temperature range of -10°C to +55°C, the FS1B is suitable for most control panel locations, whether on-board or external to the protected equipment.
