Control and monitor four optically isolated inputs and four dry-contact Reed relay outputs via an internal USB connection with the 8111-KT. Inputs can range from 5-30VDC and provide 3500VDC (2500VAC RMS) isolation to ground, while the Reed relays provide long-life switch closures well suited to low-current devices. Each Reed relay has a discrete common and each pair of inputs share a common. Status LEDS display I/O activity and field wiring is simplified via 3.5mm removable terminal blocks.

The SeaMAX software suite supports the SeaDAC Lite family and is designed to work with third party applications via the SeaMAX API. Sealevel's SeaMAX software drivers and utilities make installation and operation easy using Windows and Linux operating systems.

The 8111-KT is USB bus powered, so no external power supply is needed. A 2mm 4-pin Molex vertical header provides an internal USB connection to your host system. Standard operating temperature range of SeaDAC modules is 0C to +70C and extended temperature range (-40C to +85C) is optional.

The intelligent Porthole design is perfect for expanding industrial computing platforms using only an internal USB connection. iPorthole modules include an intelligent USB I/O board with Sealevel's innovative Porthole mounting plate for installation in a Relio or custom enclosure. Simply design the 3.2" x 3.1" Porthole mounting footprint into your enclosure to mix and match iPorthole USB I/O modules for maximum configurability. The Porthole footprint offers a standardized method for interfacing real-world I/O connections.
