The SeaI/O-570N, designed using the Linear Technology LTC1867 A/D chip, adds eight single-ended 16-bit analog inputs, eight optically isolated inputs and eight 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-570N easily connects using an RS-485 input. Cabling is accomplished via the RJ45 pass-through connector or removable screw terminals. RS-485 line conditioning allows easy configuration of termination and pull-up/pull-down resistors via external dipswitches.

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 I/O network.
