Ohaus 5000 and 7000 Series Indicators. The AC relay kit is used to control up to
three external AC circuits. The DC relay kit is used to control up to three external DC
circuits. Each solid-state relay output is equivalent to a single pole, single throw
switch (SPST). Each relay circuit is protected by a replaceable fuse.
Applications include: driving external Over/Accept/Under displays, motor controls for
semi-automatic filling systems, sorting systems, interfacing to industrial PLC
systems, etc. The Relay outputs can also be used as slave relays to drive higher
power relays in larger systems.
