Chapter 3 Functional Description

3.1 Introduction

This card provides 32 high current Darlington Open Collector ( OC ) drivers connected to a 50 position panel connector. The Darlingtons are packaged 8 to a SIOC chip. Each driver is diode clamped inside the IC and the diodes are connected to a common output. The front panel connector contains +5V or +12V power supplied from the PWA. Use of an external power supply is also available through the front panel connector. The unit is completely compatible with PXI specifications. The module operates in the register only mode, which allows ease of design of complex switch systems.

Chapter 6 Programming

The Model 7017 is a PXI register based card assembly design to be used with PXI standard chassis. The Model 7017 can be programmed in 8, 16 or 32 bit wide data format. Through your PXI controller, write the data to the appropriate register as shown on the register map for the relay or relays in the register that is being closed. When the data bit is true, the relay chosen will be closed. The state of the relays in a register can be determined by reading the desired register. Data read back represents the value of the desired register. In addition, you can read back the coil state to verify that the coil is driven correctly by the program register. This scenario verifies that the program register has correctly controlled the relay coil.

The register map is organized to show the relay designation in each register. It is followed by the register’s functionality and the path connections to the front panel. PXI will automatically assign the starting address of the card, called Bar0. This will be the starting address of the first register. Each address location controls 8 bits. Shown are the control functions using 16 format.

Programming of the Model 7017 is very straight forward. The module is organized as a 32 channel driver. The location of the first register is assigned by the PCI enumerator. This is designated as “Bar0” or the starting address of the card. The program registers using 16 bit format are located as follows:

Register #1: read/write function: Bar0 + 0000h

Chapter 8 Configurations

The Model 7017 can exist as three different configurations. +5 V Power * E1 connected to E2 and E7 connected to E8. * Resistors Networks R16,R17,R19,R20,R23,R24,R25,R26 = 100 Ohms. +12 V Power * E3 connected to E4 and E9 connected to E10. * Resistors Networks R16,R17,R19,R20,R23,R24,R25,R26 = 20K Ohms External Power * E5 connected to E6 and E11 connected to E12. * Resistors Networks R16,R17,R19,R20,R23,R24,R25,R26 = As determined below. The resistor value chosen depends on the value of the voltage chosen. The object is to always provide a 4V logic signal to the input registers.

The value of R16,R17,R19,R20,R23,R24,R25,R26 is determined as follows: Rx = [( 10k )(Vr-4)]/ 4 Where Vr is the external voltage chosen Answer is in K-Ohms

The resistor packs are isolated resistors in a low profile 8 pin SIP package similar to BOURNS Type 4606X-102-xxy, where "xx" are the significant digits and " y" is the number of zeros following the significant digits.



Chapter 9 System Power Considerations A number of items need to be considered when designing a system using the Model 7017. 1. Driver IC Specifications The type of drivers used in the Model 7017 are Micrel p/n MIC2803BWM or ALLEGRO p/n ULN2803LW. These parts have 8 drivers per IC package. The maximum power dissipation per package is 1.5 W. The maximum power dissipation for any one driver is 1.0 W. ( P = Vce(sat) x I )

2. Number of Drivers Active at One Time. The number of drivers active at one time depends on the current drawn. Based on the IC power specification, a different number of drivers could be active at any one time. For example: All 32 drivers could be active if the current is less than 100ma per driver. or 8 drivers ( 2 from each IC package ) could be active if the current is less than 400ma per driver. 3. Chassis Power Considerations The amount of power available from the PXI chassis being used must taken Into consideration for +5V or +12V operation. Power supply limitations may Preclude even the examples shown above. The +5V supplies generally have a large current limit ( >20 A ) and each PXI is fed by 5 power pins from the backplane. The +12V supplies have considerable less current available. In addition the +12 V is supplied to each PXI card with only a single pin from the backplane. This single pin is limited by the PXI specification to 1 A ASCOR recommends the following: The total current drawn for +5V driver operation should be less than 2.75 A.
