OSSD signals are the outputs from the protective device (light curtain or scanner) to a safety relay. OSSD outputs are typically semiconductor or transistor outputs, as opposed to relay or contact type outputs. There are usually two independent channels, so-called OSSD1 and OSSD2.

Jun 24, 2024 · Safety light curtains require OSSD1 and OSSD2 (Output Signal Switching Devices) mainly to provide double safety protection, ensuring that the power supply of mechanical equipment can be reliably cut off when a fault occurs or potential danger is detected, thereby protecting the safety of personnel and equipment.

Typically there are two OSSD signals, namely OSSD1 and OSSD2. Both these signals are used to monitor the switch states of the light curtain, and can be interpreted by higher level safety controllers or other safety-related systems.

OSSD1 and OSSD2 form a pair of safety outputs that output the same status. The OSSD is connected to the safety-related control system. It is wired to a force guided relay, magnet contactor, or safety controller. Safety Input. This can be connected to the OSSD of another GS, allowing for cascading.

There are usually two independent channels, referred to OSSD1 and OSSD2. This technology makes it easy to monitor short circuits up to the highest safety level (PLe according to EN ISO 13849-1). Many components with OSSD outputs are …

The safety relay ReLy OSSD2 is an electrical switching device with inputs and outputs. The safety capable inputs of the safety relay are connected to safety sensors or safety switches.

May 9, 2023 · Figure 2 OSSD signal levels from IEC 61131-2. If the OSSD is on a sensor to detect someone approaching a robot, then it is ON (+11 to +30V output) when nobody is approaching and off (-3V to +2V) when a person is detected. The fact that off includes 0V ensures that in the event of a power failure in the sensor, the robot will be stopped.

Jul 11, 2023 · OSSD1 and OSSD2 represent the dual-channel PNP signal output of the safety grating, also known as the abbreviation of Output Signal Switching Device or Optical Signal Switching Device. These terms are mainly used in product descriptions of safety light curtains.

An OSSD (Output Signal Switching Device) is a safe switching output in the form of a safety output. An OSSD is the part of the safety component that is connected to the machine …
