SECTION 2 - TECHNICAL DESCRIPTION pickering SECTION 2 - TECHNICAL DESCRIPTION FUNCTIONAL DESCRIPTION A functional block diagram is provided in Figure 2.1. The Power Relay Module is powered by +3.3V and +12V inputs via the Compact PCI connector (PXI versions) or PXIe Connectors (PXIe versions). The interface to the user test equipment is via a front panel mounted male 20-pin Positronic Scorpion connector.

Modular products require installation in a suitable PXI/PXIe/LXI chassis. The module is 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.
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.
Figure 3.2 - General Soft Front Panel Icon A selector panel will appear, listing all installed Pickering PCI, PXI or LXI switch cards and resistor cards. Click on the card you wish to control, and a graphical control panel is presented allowing operation of the card.

SECTION 4 - PROGRAMMING GUIDE pickering MODULE ARCHITECTURE - SPST The 40/42-166-001 is an array of 10, and the 40/42-166-002 is an array of 5 independent power relays. The relays are single pole, single throw and in the default state, all signal paths are open. Energising a particular relay creates a signal path between the C and A terminals.

For PXI modules which are supported in one of Pickering Interfaces’ Modular LXI Chassis (such as the 60-102B and 60-103B) no module software update is required. If the module was introduced after the LXI chassis was manufactured the module may not be recognized, in this case the chassis firmware may need upgrading.
