A popular output choice, relay output modules can drive both AC and DC loads. Relay modules offer no source power but provide NO/NC contacts that switch user-supplied power on and off internally, allowing for higher current loads. Do-more H2 series PLC relay output modules provide up to 12 points of AC/DC switching with replaceable fuses on select models.
