eI/O Configurations & Specifications
110 SERIES – 4 OPTICALLY ISOLATED INPUTS/4 FORM A REED RELAY OUTPUTS
eI/O-110 modules provide 4 optically isolated inputs and 4 Form A Reed Relay outputs. Inputs can range
from 5-30VDC, while the Form A Reed Relays provide long life switch closures that are well suited for low
current applications. Each pair of inputs shares a common and field wiring is simplified via 3.5mm field
removable terminal blocks.
Do not connect protective earthing or protective bonding conductor wiring of any equipment to relay
contact outputs.
