GE VMIVME-2232 32-Channel Relay Output Board

GE VMIVME-2232 32-Channel Relay Output Board

DESCRIPTION

This board may be ordered with positive  or negative true relay drivers. With positive true drivers, a  relay is energized when a VMEbus logic one is written to the  corresponding relay driver. Also, when using negative true  drivers, a relay is energized when a VMEbus logic zero is  written to the corresponding relay driver.

FEATURES

• Contact ratings 

— 60 W, 125 VA maximum switching power 

— 220 VDC, 250 VAC maximum switching voltage 

— 2 A maximum switching current 

— 3 A maximum carry current 

• Optional contact protection electronics for DC operation 

• 8-, 16-, or 32-bit data transfers 

• Built-in-Test (all active components are tested) 

• Front panel with fail LED 

• Compatible with the Intelligent I/O Controllers 

• VxWorks driver available 

• Software compatible with the VMIVME-2532 and the VMIVME-2533

OUTPUT SPECIFICATION SUMMARY

Output Connector Type: Dual 50-pin compatible  connector (SCSI)

Output Organization: Four ports 8 bits wide

GENERAL SPECIFICATION SUMMARY

Compatibility: VMEbus specification-compatible  double height form factor

Built-in-Test Features: This board is designed with  internal logic that contains the state of each relay coil.  This data can be read by the host during on-line or  off-line operations to monitor the condition of the board.  The data read back by the host will depend upon the  board’s mode of operation.

During off-line operations, the test mode is active. The  board enters test mode under software control, on-board  power up, or after a system reset. In test mode, the relay  drivers are disabled, as a safety precaution, to prevent the  relays from coming up activated. Special test data can be  written to the board, and read back, as a health test for  the data path to the relay drivers. The written data is read  back from the output registers used to control the relay  drivers. Unlike the on-line test described below, the data  read back is true, not inverted.

Addressing Scheme: Four ports addressable on 8-,  16-, or 32-bit boundaries in the short I/O addressing.  These ports are accessed as 8-, 16-, or 32-bit words.

Address Modifiers Codes: Jumper-selectable for  short supervisory and/or short nonprivileged I/O access.  Factory configured for short supervisory I/O accesses.

Control and Status Register (CSR): A Control and  Status Register (CSR) is provided to control the front  panel Fail LED, internal Built-in-Test features, and to  enable/disable the relays.

Board Address: Address selection jumpers are  provided to select board addresses within the short I/O  memory map.

Fail LED: A front panel Fail LED is provided. The LED  is illuminated at power up and extinguished under  program control.
