Call for price


Control and monitor four Form C (SPDT) relay outputs via an internal USB connection with the 8115-KT. The high-current Form C relays can switch up to 6A loads at 250VAC and up to 5A at 60VDC. Each Form C relay has a discrete common and can be wired for either normally open or normally closed operation. 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 8115-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.
