3.9 H-DO Module
3.9.1 Outline
The H-DO module is used specially for digital output.
H-DO-A, H-DO-B and H-DO-D type modules can output alarm statuses* such as temperature and
heater break alarms independently for each channel.
* Alarm statuses of Temperature alarm 1, Temperature alarm 2, Burnout alarm, Heater break alarm, Loop
break alarm, AI alarm 1, and AI alarm 2.
For H-DO-C type modules, dedicated alarms or control unit operations can be independently output as
event outputs.
