VTI Instruments SM2001 10/20 SPST 10A, Power Switch Module
Feature:
Type: Power
Switching Time: 10ms
The SM2001 and SM2002 10A switch modules are the first to break
the 8A switching barrier found on other VXI power switching
cards. Up to 120 10A SPST or 72 SPDT relays can be accommodated
in two VXIbus card slots for maximum density, or mixed and
matched with other SMIP TM cards for flexibility. Some applications
include: AC line power switching, switching of DC or AC power
supplies, control or driving relays for industrial machines (robotics,
numerical control machines), automotive engine control, and
solenoid switching.
All relays are driven from the VXIbus +5V supply line since VXIbus
mainframes always have ample current capability on this supply
line, as opposed to the +24 or +12V supply lines. Since these
modules typically switch power to the UUT or interface, a fail-safe
interrupt input line is provided on the front panel that can open all
relays automatically if a safety condition occurs.This approach
