Overview

Control and monitor four optically isolated inputs and four high-current Form C relay outputs via any 10/100Base-T Ethernet connection with the 120E digital I/O module. Inputs can range from 5-30V DC and provide 3500V DC (2500V AC RMS) isolation to ground, while the high-current Form C relays can switch up to 6A loads at 250V AC and up to 5A at 60V DC. Each Form C relay has a discrete common and includes normally-open and normally-closed contact connections. Each pair of inputs shares a common and field wiring is simplified via 3.5mm field removable terminal blocks.

The 120E receives power via a removable spring-clamp terminal block. The lever-style clamping mechanism requires no tools, which simplifies field installation. The module is powered by your 9-30V DC source, or select from a variety of Sealevel power supply options.

Ready for DIN rail mounting, the 120E includes a removable plastic clip that snaps onto 35mm DIN rail. The clip can also be attached to any flat surface such as a wall or under a counter. Standard operating temperature range of eI/O Ethernet digital I/O modules is 0C to 70C. Status LEDs on the front show power and I/O activity. Additionally, LEDs on the RJ45 connector display Ethernet link and communication activity.

Communicate with eI/O Ethernet digital I/O modules using industry standard Modbus TCP protocol or Sealevel SeaMAX software. The SeaMAX suite is designed to work with third-party applications via the SeaMAX API. Sealevel SeaMAX software drivers and utilities make installation and operation easy using Windows and Linux operating systems.
