AS-Interface Safety at Work
- Monitoring of up to 31 safe AS-i slaves
- Areas of application: door monitoring, light curtains, e-stop, two-hand control
- Safe AS-i modules for field applications and control cabinets
- Safe AS-i door switches with guard locking and guard lock monitoring

AS-Interface is a simple and economic wiring system for the first level of industrial communication. An AS-Interface network consists of a control unit, the so-called master, the modules for signal processing, and the associated sensors and actuators.
Safety components can easily be incorporated into an AS-i network via AS-Interface Safety at Work. Signals from standard units and safe components are transmitted via a common cable.
The fail-safe AS-i PLC is certified for use in safety-related applications up to SIL 3, PL e.
AS-i safety monitors are used to monitor safety components in AS-i systems. They monitor the code sequences to be transmitted in the AS-i network. In the case of message deviations or timeouts the monitor ensures the safe state of the system.
Safe AS-i modules detect safety-related switching states of 1- or 2-channel E-stops, position switches or door contacts. Using the safe input module safety-related components without integrated AS-i interface can be connected to the AS-i system.

Safety equipment on machines
- Fast and easy adjustment of safety light curtains and grids
- Reliable verification of the resolution of the safety light curtains
- Efficient vibration damping
- Reliable deflection of the light beam
- Protection of hazardous areas from several sides

Adjustable angle brackets and mounting bases ensure quick, easy and low-cost mounting and fixing of safety light grids and curtains.
Corner mirrors for safety light grids and curtains are used to protect hazardous areas with access from several sides.
The laser adjustment aid for safety light curtains works with visible laser light. This ensures fast and easy alignment of the transmitter and the receiver. The proper function of the safety light curtains must be checked by means of an appropriate test rod before work starts.

Fail-safe inductive sensors
- Certification to EN 60947-5-3 for electromechanical controlgear
- Ensuring operator and machine safety
- No special actuator for electronic fail-safe sensors required
- Connection to safety plc or safe AS-i module
- Series connection of sensors and contacts possible

Safety technology in automation has a share of the responsibility for safe human-machine interaction. Fail-safe sensors with safety functions are an important part of a safety system for persons and machines. The operating principle and thus the advantages of inductive sensors can also be used for safety applications. Direct detection of metal solves many applications. Magnetic or mechanical counterparts do not have to be considered in the design. A wear-free function due to the non-contact principle and a high protection rating guarantee high uptime of the machines and installations.

No special demands such as shielding, twisted cables or laying separately, are made on the socket. The sensor is directly connected to existing PLCs or logic modules using common existing unshielded 4-pole cables. The output characteristics of the sensor follow the characteristics of an input to EN 61131-2 type 1 or 2. Connection to ifm evaluation relays, AS-i Safety at Work, PROFIsafe, Interbus Safety bus systems or safe PLCs and logic modules is equally simple. For the unit family with dynamic pulse detection (Gx50xS) the corresponding software modules are required. The fail-safe sensors with 2 x PNP output (Gx70xS; Gx71xS) can be connected to approved two-channel safety relays without cross-monitoring. The evaluation units from ifm electronic enable functionalities such as muting or connection of e-stop devices to DIN EN 60947-5-1 without extra cost.

A magnet or coded target is not necessary for the function of the fail-safe sensor.

Safety controllers
- Safe inputs and outputs
- Layered safety concept, extended monitoring and test routines
- Performance configurable in case of a fault
- Quick boot-up and short fault detection time
- High-performance CAN interface for various communication tasks

The powerful, freely programmable 32-bit SafetyControllers are designed for use in harsh conditions. They are suitable for direct installation in vehicles and mobile machines using the on-board system. Thanks to special integrated hardware and software functions for safety-related tasks, these controllers can be used as safety controllers.
Hardware and software have been certified by the German TÜV association. The programmable, layered error handling feature ('Keep Alive') enables the SafetyController to switch off in case of a serious fault and bring the plant into a safe state. In case of less serious errors however, parts of the plant in previously defined areas can still be used. Not all components have to be switched off. The behaviour of the inputs and outputs can be adapted to the application easily and precisely using the CODESYS programming software.

Safety relays
- Evaluation units for fail-safe sensors and E-STOP switchgear
- Connection of mechanical fail-safe switches and fail-safe sensors
- Evaluation systems for safe rotational speed or standstill monitoring

Safety relays can be used in a variety of ways. They perform monitoring tasks in safety applications in combination with different non-contact guards. They are capable of evaluating signals from safety light grids, safety light curtains, position sensors with and without cross-fault monitoring, electronic safety sensors or mechanical safety switches for protective guard contacts.
Safety relays with relay outputs and muting function are used for the connection of safety light curtains and safety light grids. In handling and loading stations, the muting function reliably differentiates between the entry of personnel and material.
Standstill monitors and speed monitors are pulse evaluation systems for safe detection of underspeed or standstill or for safety-related minimum speed monitoring.
