8 Optically Isolated Input / 8 High-Current Form C Relay Output SeaI/O Expansion Module

SEALEVEL 520N
SeaI/O-520N |
|
| |
The SeaI/O-520N adds 8 optically isolated inputs and 8 high-current Form C relay outputs to your SeaI/O network. Compatible with all SeaI/O base units (Ethernet, USB, RS-485, RS-232), the SeaI/O-520N connects easily using an RS-485 input. Cabling is accomplished via the units RJ45 connector or removable screw terminals. RS-485 line conditioning allows easy installation of termination and pull-up/pull-down resistors.
All SeaI/O N-series expansion modules ship with an expansion and strap kit that includes four metal straps, four #4-40 screws, and a 5” RJ45 RS-485 interconnect cable. The metal straps allow you to connect multiple SeaI/O modules together in a "stack". The interconnect cable can be used to connect SeaI/O modules together via the RJ45 pass-through connectors, providing an easy method to cascade RS-485 signals and power from one module to the next. Alternatively, use inexpensive CAT5 cabling to pass data signals between SeaI/O modules to create a distributed network.
