2.2.6 PDE3530 - Remote Panel Driver Card
The PDE 3530 card contains the I2C serial I/O circuitry required to drive the remote panel. This provides
a bi-directional serial data line for sending LED data and receiving switch data from a remote panel
containing the PDE 3531 PCB.
The D-type connector on the PDE 3530 also provides the DC supply for the remote panel.
2.2.7 PDE3531 - Custom Panel Card
The PDE 3531 card provides the necessary interface for display, switch and lamp combinations in a
remote control panel. PDE3531 cards have a modular design and may be cascaded as required.
2.2.7.1 PDE3531 Operation
The PDE3531 board is segmented into three parts. These are P(power), SL(switch lamps), and
D(display). Two configurations are available:
1. 1.The first PDE3531 card used in a remote panel must be of P/SL/D configuration. The PDE3531/
P/SL/D card contains the I2C line transceivers, psu circuitry and switch/lamp bank selection.
2. 2.Subsequent cards are of SL/D configuration, containing a four-bit comparator to enable the bank
and five, eight-bit ports. The ports are divided as follows: one for inputs, two for outputs capable of
lamp drive, and two for LED display interface.
Up to seven cards can be cascaded for switches or lamp combinations, including up to four with LED
displays.
Remote pots can only be supported by the addition of a version of the 4003 variable level control panel
serving as an extension to the 4016 Custom Panel Interface.
2.2.7.2 PDE3531 Installation Information
The remote panel can be connected to the 4016 interface over a maximum distance of 20m using a 15-
way screened cable or screened ribbon cable.
On the PDE3531 card:
Switch/lamp cable runs (from CON5-CON7 on the SL section) should be 7/0.2 cable contained within
the same panel box as the PCB to maintain EMC compliance.
LED display cable runs (from CON4 on the D section) can be up to 1m long and should be contained
within the same panel box as the PCB to maintain EMC compliance.
SL/D to SL/D connections (from CON1 on the SL section) should be a maximum of 150mm using a
screened ribbon cable.
Switch settings to configure each card for its panel function i.e. right-hand side of the keypad, Direct
Access keys 1-8 etc. are shown in the table below.
