voltage (≤ 25 V AC or 60 V DC).| |---|---| ||Against adjacent modules in the support rail direction at least one
functional insulation on the output-side is complied with. If the
application has higher requirements on the insulation (basic insulation
or reinforced insulation), then these must be realized through suitable
measures (e. g. partition plates).| ## Dimensions |Width|112.5 mm| |---|---| |Height|58.5 mm| |Depth|77 mm| |Ambient conditions|| |Ambient temperature (operation)|-20 °C ... 50 °C| 01/02/2020 Page 1 / 8 https://www.phoenixcontact.com/gb/products/2281157 ## Interface module - FLKM-D50 SUB/S - 2281157 ## Technical data ## Ambient conditions Ambient temperature (storage/transport) -20 °C ... 70 °C Maximum altitude ≤ 2000 m Degree of protection IP20 ≥ IP54 (Installation location) General Max. permissible operating voltage 25 V AC 60 V DC Max. permissible current 2.5 A (per path) Max. permissible total current 90 A (TA = 50°C) Number of positions 50 Mounting position any Assembly instructions In rows with zero spacing ~~i~~ Connection data Connection name Field level Connection in acc. with standard IEC / EN Connection method Screw connection Stripping length 8 mm Screw thread M3 Conductor cross section solid 0.2 mm² ... 4 mm² Conductor cross section flexible 0.2 mm² ... 2.5 mm² Conductor cross section AWG 24 ... 12 Connection data 2 Connection name Controller level Connection method D-SUB pin strip Number of positions 50 ~~—~~ Standards and Regulations Connection in acc. with standard CUL Designation Air clearances and creepage distances Standards/regulations DIN EN 50178 Rated insulation voltage 125 V Rated surge voltage 1.2 kV Insulation Functional insulation Pollution degree 2 Overvoltage category II Environmental Product Compliance Lead 7439-92-1 China RoHS Environmentally Friendly Use Period = 50 ~~SS~~ 01/02/2020 Page 2 / 8 https://www.phoenixcontact.com/gb/products/2281157 ## Interface module - FLKM-D50 SUB/S - 2281157 ## Technical data Environmental Product Compliance For details about hazardous substances go to tab “Downloads”, Category “Manufacturer's declaration” ~~pp~~ ## Drawings ## Circuit diagram ## Classifications ## eCl@ss |eCl@ss 4.0|eCl@ss 4.0|27250300| |---|---|---| |eCl@ss 4.1|eCl@ss 4.1|27250300| |eCl@ss 5.0|eCl@ss 5.0|27250300| |eCl@ss 5.1|eCl@ss 5.1|27250300| |eCl@ss 6.0|eCl@ss 6.0|27242600| |eCl@ss 7.0|eCl@ss 7.0|27141152| |eCl@ss 8.0|eCl@ss 8.0|27141152| |eCl@ss 9.0|eCl@ss 9.0|27141152| 01/02/2020 Page 3 / 8 https://www.phoenixcontact.com/gb/products/2281157 ## Interface module - FLKM-D50 SUB/S - 2281157 ## Classifications ETIM ETIM 4.0 EC002780 ETIM 5.0 EC002780 ETIM 6.0 EC002780 ETIM 7.0 EC002780 ~~SSS~~ UNSPSC UNSPSC 6.01 30211824 UNSPSC 7.0901 39121421 UNSPSC 11 39121421 UNSPSC 12.01 39121421 UNSPSC 13.2 39121432 UNSPSC 18.0 39121432 UNSPSC 19.0 39121432 UNSPSC 20.0 39121432 UNSPSC 21.0 39121432 ~~——~~ Approvals Approvals ## Approvals UL Recognized / cUL Recognized / EAC / cULus Recognized ## Ex Approvals Approval details > UL Recognized  http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.htm FILE E 118976 Nominal voltage UN 125 V Nominal current IN 2.5 A mm²/AWG/kcmil 30-12 ~~————~~ > cUL Recognized  http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.htm FILE E 118976 Nominal voltage UN 125 V ~~———E~~ 01/02/2020 Page 4 / 8 https://www.phoenixcontact.com/gb/products/2281157 ## Interface module - FLKM-D50 SUB/S - 2281157 ## Approvals |Nominal current IN|2.5 A| |---|---| |mm²/AWG/kcmil|30-12| EAC  cULus Recognized  RU C- DE.A*30.B.01742 ## Accessories Accessories System cable Cable - CABLE-D50SUB/B/S/ 50/KONFEK/S - 2302269 Assembled shielded round cable;
