Protected VARAN Digital Mixed Module Digital Inputs Galvanic isolation Input voltage The protected VARAN Digital Mixed Module PVDM 087 has four digital outputs +24 V/2 A (positive switching and four digital inputs. In- and outputs are gavanically separated from the VARAN bus. Inputs and outputs have a separate supply. The outputs are also back-readable. There are also diverse diagnostic functions available in this module. Input filters are available to suppress noise signals occurring in the signal lines. Next to the I/O connectors, LEDs show the signal status as well as the error status. The VARAN Out port allows the construction of the VARAN bus in a line structure. The component has IP67 protections. Maximum sensor supply current Signal level Switching threshold Input current Maximum allowable residual current Input delay Status display yellow LEDs Electrical Requirements Bus supply voltage Current consumption of the bus supply Current consumption of I/O supply depends on the load of the digital outputs and the current capacity on the sensor supply: maximum 4 A Article Number and Miscellaneous Interfaces Interfaces Short-circuit proof Galvanic isolation Voltage drop over power supply (output current 4 A) Environmental Conditions Maximum total current Software macro Dimensions 1x VARAN In (M12) (maximum length: 100 m) 1x VARAN Out (M12) (maximum length: 100 m) Digital Outputs Maximum continuous current load/ channel Article number 4 A (50 % of on time) 4 A (50 % of on time) 2 A (100 % of on time) Operating temperature Mounting position EMC stability Shock resistance Protection type Residual current (inactive) Turn-on delay Turn-off delay Status display yellow LEDs
