8030-HOM-221. The Symax Class 8030 Type HOM-221 8 Function 120VAC Output Module contains 8 optically isolated outputs, each capable of driving loads such as motor starters, solenoids, or pilot lights. A red LED indicator on the front of the module for each output illuminates when the processor issues a command to energize that output. Two neon lamps on the front of the module, one for each group of 4 outputs, illuminate when a blown fuse is detected. A marking area is provided next to each LED for output identification.
