Outputs
The controller directly accommodates switched dc and
open-collector outputs only. These outputs can be used to
control a wide variety of loads. They are typically used to
control SSRs or other power switching devices which in
turn control, for example, heaters. They may also be used
to signal another device of an alarm condition in the con-
troller.
Analog outputs may be accomplished by using Dual DAC or
Serial DAC modules in conjunction with one of the control
outputs.
An open-collector CPU watchdog output is also provided so
that an external device may monitor the CPU state.
