160PoE overview


Control and monitor up to 32 channels of buffered drive digital I/O via any 10/100BaseT Ethernet connection with the 160PoE digital I/O module.

The module addresses the 32 channels of I/O as four eight-bit ports, each programmable as input or output. Use a standard 50-pin IDC ribbon cable to connect an industry standard relay rack for PC based control and automation of equipment including sensors, switches, security control systems, and other industrial automation systems. The 160PoE 50-pin (TTL) digital interface is pin compatible with the Sealevel SeaDAC Lite 8126 and accepts the same accessories.

The 160PoE is a Class 0 (IEEE 802.3af-2003) Power over Ethernet device. This allows power and data to be transferred over a single CAT5 cable and eliminates the need for an external power supply. With PoE, power can be supplied by power sourcing equipment including PoE injectors (midspans) and switches (endspans).

Ready for DIN-rail mounting, the 160PoE 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 0°C to +70°C. Status LED's on the front show power and I/O activity. Additionally, LED's 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 use the Sealevel SeaMAX API software libraries from your application program. Sealevel's SeaMAX software drivers and utilities make installation and operation easy using Microsoft Windows operating systems.

The Sealevel Modbus Connect app for iOS allows you to access the registers, coils and discrete I/O of your Sealevel Modbus devices and is available on the App Store. Use the app to remotely access I/O in the field or for testing and troubleshooting during application development.

Impulse is the exclusive UK distributor of Sealevel products and can supply you the 160PoE along with a wide range of accompanying industrial computing and communication products.
