For your safety
The unit meets all the necessary conditions for safe operation. However, please note the
following:
} Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120
VDC) are present on the unit, connected control elements and sensors must have a rated
insulation voltage of at least 250 V.
Unit features
} Positive-guided relay outputs:
– 3 safety contacts (N/O), instantaneous
– 1 auxiliary contact (N/C), instantaneous
} 2 semiconductor outputs
} Connection options for:
– 2 control elements (pushbuttons)
} LED display for:
– Supply voltage
– Switch status of the safety contacts
} Semiconductor outputs signal:
– Supply voltage is present
– Switch status of the safety contacts
Safety features
