How to Add External Alarms to the 5 Digit Display Controller?

Hi everyone, I have an ATO-DDC5-CHB 5 digit display controller, and I want to add external indicators for the alarms. Where can I find the output voltage necessary for these alarms? What are the size requirements? Voltage? Amps? etc.? Thanks.

Hi Tobias, for the ATO-DDC5-CHB, this unit has 2 sets of alarm outputs, AL output and AH output (with normally open and normally closed contacts).
The contact capacity is 250VAC/3A, resistive load, and the corresponding parameters are OUT1 and OUT2. Please refer to the attached manual for instructions.

I want to confirm that the product will work with US circuits of 110 to 115 volts, as this was the power cable supplied. I want to ensure we don't damage the product and that we have everything we need.

This unit TY5D/A3 operating voltage supports the 110V voltage of the United States.
No problem. As long as the working voltage is available in the range of 100-240VAC.
