GENERAL DESCRIPTION 

 
The  M218  provides  16  one-wire  switches  on  a  single  wide  M-Module  adhering  to  the 
ANSI/VITA  12-1996  specification  for  M-Modules.    The  M218  may  be  installed  on  any  carrier 
board  supporting  the  M-Module  specification.    Carriers  are  available  that  allow the M218 to be 
used in Ethernet, VXI, VME, PCI, cPCI and other system architectures. 
 
1.1

 

PURPOSE OF EQUIPMENT 

 
The M218 is a general purpose relay switch that can be used to connect test points on a device 
under test to instrumentation or to switch factory automation and fixturing. 
 
 

CAUTION: 

This module uses latching relays that retain their last programmed 
state whenever power is removed (closed relays will remain closed 
until opened via your test program).

  

 

CAUTION: 

This  module  DOES  NOT  have  provisions  for  on-board  current 
limiting  components  (if  input  current  can  exceed  2A  DC  or  2A 
AC, you must install external current limiting circuitry)
