  • Page 17: Installation

    Modular products require installation in a suitable PXI/LXI chassis. The module is designed for indoor use only. PREOPERATION CHECKS (UNPACKING) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident.
  • Page 18: Hardware Installation

    For a system comprising more than one chassis, turn ON the last chassis in the system followed by the penultimate, etc, and finally turn ON the external controller or chassis containing the system controller. 9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up sequence.

    MODULE ARCHITECTURE 40-280-021/121 The 40-280-021 is an array of 48, and the 40-280-121 is an array of 96 SPST relays. In the default state, all signal paths are open circuit. Energising a particular relay creates a signal path between the C and A terminals. The relay module’s channel architecture is shown in its default state in the diagram below.
