Relay Modules
Safety gate monitoring
Safety gate monitoring modules watch the position of movable safety devices by interrogation of safety switches which are operated by safety device opening/closing.
Safety gate monitoring
- Wide range of products for a variety of applications
- All products comply with the safety category 4 acc. to EN 954
- Type-tested circuits in compliance with relevant norms
- Prewired modules for DIN rail mounting
Safety switches
- Reliable position monitoring of safety devices, e.g. safety gates
- Suited for raw environments thanks to hermetically sealed housing up to IP 67
- Long service life by wearless switching and proximity operation
Safety gate monitoring
Safety gate monitors are designed to comply with the safety category 4.
Line faults and interruptions can be detected by XOR arrangement (combination of NO and NC contacts).
Depending on model the position switches can be monitored for simultaneity with different time tolerances.
Safety switches
Safety switches are available either as Reed switches or with semiconductor outputs. They consist of an actuator and a sensor as decoder. The actuator is magnetically encoded. Sensor contacts switch when the sensor detects the encoding of the actuator.
DOLD’s safety switch NE 5020 has a cross fault detection function. When a fault occurs the output contacts of the evaluator are cut off for safety reasons and a restart is prevented. The safety switches are protected against short-circuit currents and interfering voltage pulses.
Safety gate monitoring
Safety gate monitors can be used for all applications where movable protective devices (safety gates) are required. This is the case where entering into or access to an area with dangerous movements for the purpose of machine operating, setting or fault elimination require such a safety device.
Safety switches
Proximity-operated safety switches are suited for position monitoring of sliding, hinged or detachable safety gates and guards, even in heavily polluted environments or for applications with stringent hygienic requirements. These products can also be used for sluggishly or inaccurately closing gates.
