The Basic I/O 1

DIGITAL OUTPUTS:

Digital output modules, commonly referred to as solid state relays, control external AC or DC power sources. A dry-contact (mechanical relay) with very low contact resistance is also available.

Digital output instruction types are:

Set outputs

Can set individual or multiple outputs On or Off.

Pulse Generator

Can generate 1 to 65,535, 50% duty cycle pulses whose equal

 

On and Off periods can range from 0.01 to 2.55 seconds.

 

Resolution can be reduced by a factor of 1-256 on a system

 

wide basis to increase the maximum pulse width available.

Modifiers:

 

One Shot

Can generate On or Off pulse durations of up to 10.9 minutes

 

with a resolution of 0.01 seconds. Resolution can be reduced by

 

a factor of 1-256 on a system wide basis increasing duration up

 

to 46 hours. Re-triggering is available.

Delayed

Can generate delayed On or Off outputs after delaying up to

 

10.9 minutes with a resolution of 0.01 seconds. Resolution can

 

be reduced by a factor of up 1-256 on a system wide basis

 

increasing the delay before changing state up to 46.6 hours. Re-

 

triggering is available.

Square wave

Can generate square waves with programmable On and Off

 

periods. On and Off periods have a base range from 0.01

 

seconds to 10.9 minutes. Resolution can be reduced by a factor

 

of 1-256 on a system wide basis increasing duration to 46.6

 

hours.
