          How do the PDL 600 and 800 series product codes work?

          As a general rule of thumb -
          PDL items require PDL at the front of the code.
          600 series item codes start with 6.
          600 series switch codes start with 68.
          The number of switches fitted in the plate is the 3rd number in the code, 681 = single 600 series switch, 682 = double 600 series switch
          600 series socket codes start with 69.
          The 3rd digit in a socket code indicates the type of socket, 691 = single vertical socket, 692 = double vertical socket, 694 = single horizontal socket, 695 = double horizontal socket.
          Most codes require a colour code at the end, WH = white, BK = black.
          eg. To order a black double vertical switched socket the complete code would be PDL692BK.
          800 series (Modena) item codes start with 8 and follow the same format as above. (800 series items with Strato plates start with S8...)
          eg. An 800 series Modena double switch in white = PDL882WH, a Strato double horizontal switched socket in black = PDLS895BK 
          In both series metal cover plates are an extra option to be supplied separately, coded to fit the plate required, eg. 600 series single switch metal plate in Stainless Steel = PDL681MSS (M = Metal, BBZ = Brushed Bronze, PB = Polished Brass) Some plastic cover plates are available eg. PDL681CWH (C = Cover), PDL800PSCH (PS = Plastic Surround, CH = Champagne, there are 9 colour options in 800 series)
          Strato brushed aluminium plates also need BK or WH to decide the trim colour, eg. PDLS800CBABK or PDLS800CBAWH (C = Cover , BA = Brushed Aluminium)
          Module grids with covers are available in BK or WH, eg. PDL684VHWH (VH = vertical/horizontal since the grid is empty and module can be fitted either way), PDLS800GPSBK (GPS = Grid, Plate, & Surround).
          Grids without covers included are only available in Modena 800 series, PDL800G (horizontal) or PDL800GV (vertical)
          Refer for further details and options.

          What is the code for a single switch 600 series cover plate in white?

          Code = PDL681CWH

          What is the part number of the PDL mechanism to suit PDL681VH?

          The part number of the mechanism to suit PDL681VH is PDL681M20. PDL681M20 is rated to 20A/16AX, 250V AC, 1 pole, 1 way/2 way.

          User-added image

          What is the Code for the metal cover plate for the PDL685VH?

          The 685 and the 686 take the same coverplate so the code is the PDL686MSS (for stainless steel)

          Is there a white cover plate available for the PDL 681HWP?

          The PDL 681CWH is the white cover plate to suit the PDL 681HWP

          What is the permanent connection unit for the PDL 600 Series?

          There are two options available for PDL 600 series :
          Standard Item = PDL651
          Waterproof IP56 =  PDL651VWP 
          Colour options = White or Black 

          The standard PCU module only is PDL651M2, the IP56 module is not available as a spare part.

          Does the normal PDL681 have an IP56 rating?

          No it doesn't, but you can use the PDL681VWP as this is IP56 rated.
          Refer to PDL Catalogue and Pricing Guide Issue 70, page 33.

          What parts make up a PDL381-VW

          PDL381-VW  is a complete switch including grid plate & switch mechanism.

          The separate parts to make this are PDL381G + PDL381C-VW + PDL381M20

          What plate is required to fit the on/off and auto/manual switches with a 100MPIR?

          The installation sheet for the 100MPIR is at

          Please note, the code for the on/off switch is now 681M16HFS, if you want a switch with a hinged flap printed SENSOR, which is good to avoid the switch being turned off accidentally. Also please be aware of the load limitations on the PIR, it is not rated for use with LED's.

          With the 2 switches and the PIR as seen in the instructions you will need a triple plate, as long as these are the only switches you want on the plate, which is a PDL683VH. This is the grid and cover plate, available in white or black, and if you need a metal cover plate you will also need to order the PDL683M** where the ** is either PB for polished brass, BBZ for brushed bronze, or SS for stainless steel.

          There is another option if you find the triple plate too busy or you have other switches to go in the plate, there is a 3 position rotary selector switch available that does Auto Off Manual in one switch, so with the PIR you will only need 2 module holes (PDL682VH). The rotary switch code is 687M3A/M which you can see at:
