Description
SAFE-DELAY Functional Safety Module | E-Stop monitoring up to SIL 3 with time-off delayed contacts
- SAFE-DELAY is an all-purpose emergency stop device that combines non-time-delayed and time-delayed contacts
- This permits dangerous components of a system to be switched off quickly and safely in an emergency situation
- At the same time, other circuits can continue to be supplied with voltage for up to 30 seconds to allow a tool to be moved to its idle position or to brake following parts, for example. The safety module provides two safe relay contacts without any delay and two safe relay contacts with a time-off delay up to 30 seconds (can be ordered with fixed or adjustable time). Further applications for the SAFEDELAY include single or dual channel emergency stop circuits and guard monitoring on machines and plants according to EN ISO 13849-1 and EN 62061.
- Features
- 2 non-delayed safety contacts
- 2 time-off delayed contacts (adjustable and fixed)
- Continuously adjustable time delay (1 to 30 s)
- Connection of:
- Emergency stop buttons
- Mechanical safety switches
- Non-contact safety switches
- Safety components with OSSD outputs
- Control: single or dual channel feedback loop for external contactors or extension modules
- Cyclical monitoring of the output contacts LED indicator for power and status
- Automatic or manual start
- Short-circuit monitoring and ground fault monitoring
- Up to PL e/SILCL 3/category 4 (EN ISO 13849-1/EN 62061)
- Function
- The moving parts of a machine or system can be quickly and safely stopped in case of danger with the non-time-delayed contacts of the SAFE-DELAY safety contacts with time- delay switch-off are also integrated into the SAFE-DELAY
- They are used whenever it is safer to keep supplying voltage to parts of a machine after the emergency stop switch is operated
- It is ensured that a single fault or malfunction does not lead to a loss of the safety function and that every fault is detect- ed by cyclical self-monitoring no later than when the system is switched off and switched on again
- The time-off delayed contacts are activated at the same time as the non-time-delay contacts; however, when the emergency stop button is pressed, the contacts are only deactivated after the time set on the potentiometer (1 ... 30s). During timeout, no power-loss is accepted
