2.3 Input Signal Jumper Setting Note: This section is for PCI-7250, PCI-7251, LPCI-7250, and LPCIe-7250 only. There are 8 jumpers (JP1 to JP8) on the PCI-7250, PCI-7251, LPCI-7250 and LPCIe-7250; each associated with one digital input to configure that channel as either AC-Filtered or Non-ACFiltered.
2.4 Hardware Installation Outline PCI Configuration PCI cards (or CompactPCI cards) are equipped with plug and play PCI controllers which can request base addresses and interrupts according to the PCI standard. The system BIOS will assign the system resources based on the PCI card configuration registers and system parameters (which are set by the system BIOS). Interrupt assignment and memory usage (I/O port locations) can only be assigned by the system BIOS.
2.5 Device Installation for Windows Systems Once Windows Vista/XP/2003/2000 has started, the Plug and Play functions of the Windows system will find and locate the new NuDAQ/NuIPC card. If this is the first time a NuDAQ/NuIPC card is installed in your Windows system, you will be prompted to input the device information source. Please refer to the “Software Installation Guide” for installation procedures for the device drivers. 2.

2.7 PCI-7250 and PCI-7251 Connection There are 8-relay outputs and 8-isolation inputs on both the PCI7250 and PCI-7251. The PCI-7251 is used as an expansion for the PCI-7250. The operations of the PCI-7251 are the same as that of the PCI-7250. There can be at most 3 PCI-7251 expansion boards to one PCI-7250. Therefore, the PCI-7250 can control up to 32 relays and detect 32 input signals.
3 Registers Detailed descriptions of the registers are specified in this chapter. This information is useful for programmers who wish to control the card with low-level programming. However, we suggest users fully understand the PCI interface before starting any low-level programming. In addition, the contents of this chapter will also help users understand how to use the software drivers to configure this card. 3.
3.2 I/O Address Map All 725X registers are 8 bits long. Users can access these registers using 8-bit I/O instructions. Using these registers will allow the relays and status of the inputs to be controlled. The following table shows the registers address map, including descriptions and their offset addresses relative to the base address. If the PCI-7251 expansion boards are not installed, corresponding registers have no significance.
The normal open signal line is ‘open’. Bit value ‘1’ means the relay is energized and the normal open signal line is now closed. The initial bit values of the control register are all ‘0’ and the status of the relay can be readback from the readback register. If the relay is open, the corresponding bit value read is ‘0’. If the relay is closed, the bit value read is ‘1’.
32 Registers
4 Operation Theory 4.1 Using Relay Output The PCI-7250/7251 contains two types of relays: Form C and Form A. Relays R0 - R3 are form C relays, and R4 - R7 are plain form A type. Note that the LPCI-7250, LPCIe-7250, and cPCI7252 contain Form C relays only. The differences between these two types of relays are: 1.
2. Form A Relay: (R4 - R7) NO NO COM COM Control Bit = High(1) Control Bit = Low(0) Figure 4-2: Form A Relay Form A relay only has two contacts: NO (Normal Open) and COM (Common). The COM post can make contact either with the NO post or not. When the control bit is high (1), the COM post and NO post are contacted. If the control bit is low (0), the COM post and NO post does not make contact. In normal power-up and reset, the relay is in low status.
4.2 Using Isolated Input The PCI-7250 (or PCI-7251) contains 8 identical opto-isolated control input channels. The circuit diagram of the differential input channel is shown below. 2.2k Ω DInH IF VIN Ri DInL PC-814 (opto-isolator) Figure 4-3: PCI-7250 Differential Input Circuit The digital input is first routed through a photo-coupler (PC-814), which is shown in the following diagram. The cPCI-7252 contains 16 identical opto-isolated control input channels.
The LPCI-7250 and LPCIe-7250 contain 8 identical opto-isolated control input channels through PC3H4 photo-coupler. The circuit is shown as the following diagram: 2.2k Ω DInH VIN IF Ri DInL PC3H4 (opto-isolator) Figure 4-5: LPCI/LPCIe-7250 Differential Input Circuit In addition, a single-pole filter with a time constant of about 5ms is used to filter AC inputs passing through. The normal input voltage range for an active high state is 3 to 24 VAC or DC.
Appendix Relay Contact Protection Circuits The contacts are the most important elements of a relay construction, Contact performance conspicuously influenced by contact material, and voltage and current values applied to the contacts. Another important issue is contact protection; the right contact protection circuit can suppress the counter EMF to a low level. However, note that incorrect use will result in an adverse effect.
Device Selection: As a guide in selecting R and C, X R: 0.5 to 1Ω per 1V contact voltage X C: 0.5 to 1μF per 1A contact current Values vary depending on the properties of the capacitor C acting to suppress the discharge the moment the contacts open. Resistor R acts to limit the current when the power is turned on. Test to confirm. Use a capacitor with a breakdown voltage of 200 to 300V. Use AC type capacitors (non-polarized) for AC circuits. Diode Circuit This circuit is suitable for DC applications.
Diode & Zener diode Circuit This circuit is also suitable for DC application. Effective when the release time i in the diode circuit is too long. Contact Diode Inductive Load Device Selection: Use a zener diode with a zener voltage about the same as the power supply voltage. Varistor Circuit This circuit is also suitable for both AC & DC applications. Using the stable voltage characteristics of the varistor, this circuit prevents excessively high voltages from being applied across the contacts.
