    Programming the Form C Switch ..... . .27 Form C Switch Description The E1463A 32-Channel, 5 Amp, Form C Switch module (Form C switch) is defined as a VXIbus instrument. VXIbus plug-in modules installed in a mainframe or used with a command module are treated as independent instruments each having a unique secondary address.

  • Page 13: Typical Configurations

    Typical The Form C switch accepts user inputs up to 125 Vdc or 250 Vrms. Maximum rated power capacity (external load) is 150 Wdc or 1250 VA per Configurations channel. Per module, you can switch 1500 Wdc or 12500 VA. As noted, the switch may be configured for general purpose switching/scanning or digital output applications.

    CAUTION Static electricity is a major cause of component STATIC ELECTRICITY. failure. To prevent damage to the electrical components in the Form C switch, observe anti-static techniques whenever removing a module from the mainframe or whenever working on a module. The Form C switch is susceptible to static discharges.

  • Page 16: Setting The Interrupt Priority

    Setting the Interrupt The Form C switch generates an interrupt after a channel has been closed. These interrupts are sent to, and acknowledgments are received from, the Priority command module (E1406, for example) via the VXIbus backplane interrupt lines. For most applications where the Form C switch is installed in a C-Size mainframe, the interrupt priority jumper does not have to be moved.

  • Page 17: Installing The Form C Switch In A Mainframe

    Installing the Form The E1463A may be installed in any slot, except slot 0, in a C-size VXIbus mainframe. See Figure 1-6 to install the Form C switch in a mainframe. C Switch in a Mainframe Set the extraction levers out.

  • Page 18: Configuring A Terminal Module

    Configuring a Terminal Module The E1463A 32-Channel, 5 Amp, Form C Switch consists of a relay switch card and a screw type standard terminal module. In addition, a solder eye terminal module (Option A3G) is available. User inputs to the Form C switch are to the normally open (NO), normally closed (NC), and common (C) terminal connectors on the terminal module.

    Wiring a Terminal Figures 1-10 and 1-11 show how to connect field wiring to the terminal module. When making wiring connections, be sure the wires make good Module connections on screw terminals. Maximum terminal wire size is No. 16 AWG. When wiring all channels, a smaller gauge wire (No. 20 - 22 AWG) is recommended.

  • Page 23: Protecting Relays And Circuits

    Protecting Relays and Circuits This section gives guidelines to protect relays and circuits in the Form C switch, including: • Relay Life Factors • Extending Relay Life • Adding Relay and Circuit Protection • Maximum Allowable Module Switch Current NOTE Relays that wear out normally or fail due to misuse should not be considered defective and are not covered by the product's warranty.

  • Page 24: Extending Relay Life

    Replacement Strategy The replacement strategy depends on the application. If some relays are used more often, or at a higher load, than the others, the relays can be individually replaced as needed. If all the relays see similar loads and switching frequencies, the entire circuit board can be replaced when the end of relay life approaches.

  • Page 25: Adding Relay And Circuit Protection

    Adding Relay and The Form C switch has space for adding relay and circuit protection. Relay protection can be added by placing a protective device across the specified Circuit Protection pads. This is done by adding metal oxide varistors (MOVs) between the common (C) and normally open (NO) or normally closed (NC) terminals.

  • Page 26: Maximum Allowable Module Switch Current

    Maximum Allowable The Form C switch has an individual channel current specification of 5A. However, if you apply 5A to all the channels with a relay contact resistance Module Switch of .25 Ohms, the power dissipation is 200 W. Since, for example, the Current E1401B mainframe can only provide cooling for 55W per slot (to keep the temperature rise to 10...

  • Page 27: Programming The Form C Switch

    Programming the Form C Switch This section gives guidelines to program the Form C switch, including: • Using SCPI Commands • Addressing the Form C Switch • Initial Operation Using SCPI There are several ways you can program the Form C switch. One way is to write directly to the registers.
  • Page 28 Card Numbers The card number (cc of the channel_list) identifies the module within a switchbox. The card number assigned depends on the switch configuration used. Leading zeroes can be ignored for the card number. In a single-module switchbox configuration, the card number is always 01. In a multiple-module switchbox configuration, modules are set to successive logical addresses.

  • Page 84: Relay Control Register

    Relay Control There are two relay control registers: Relay Control Register 1 (base + 06 and Relay Control Register 2 (base + 08 ). These registers are used to Register connect the common (C) to the normally open (NO) terminal. Reading any Relay Control Register will always return FFFF regardless of the channel states.

  • Page 87: Example: Making Measurements (Basic)

    Example: Making This BASIC programming example closes bit 1 on bank 0, waits for a measurement to be made, and then opens the channel. You must insert Measurements your own programming code for the measurement part of this program. For (BASIC) example, if you are using the E1411B, see the E1326B/E1411B Multimeter User's Manual for programming examples.

    Example: Making This C/HP-UX programming example closes bit 1 on bank 0, waits for a measurement to be made, and then opens the channel. You must insert Measurements your own programming code for the measurement part of this program. For (C/HP-UX) example, if you are using the E1411B, see the E1326B/E1411B Multimeter User's Manual for programming examples.

    Example: Scanning This BASIC programming example scans through the bank 0 channels (closing one switch at a time) and makes measurements between switch Channels (BASIC) closures. You must insert your own programming code for the measurement part of this program. For example, if you are using the E1411B, see the E1326B/E1411B Multimeter User's Manual for programming examples.
