How many relay outputs does the HI 3010 have, and at what voltage?

The HI 3010 Filler/Dispenser standard is 4 relay outputs, with an option of 3 additional for 7 total relay outputs. The relay's are 48-240 VAC SPST N.O. (solid state).  DC voltage relays are available upon request.

It should be noted that these outputs are not assigned to any function. The relays can be mapped and assigned a task. These are solid state relays and will not operate like a dry contact relay. For operations requiring a contact closure a second relay will be required.  You would also need a secondary relay to accommodate a contact closure with a higher than 4 amp current draw.
