Rugged, High-Density Ethernet I/O

EtherStax I/O provide a dependable solution for interfacing a lot of signals to a PLC, DCS or SCADA system. A single unit can monitor or control up to 96 I/O channels

New! USB-to-USB Isolator

Protect your PC and USB devices

This small, industrial- grade isolator is very easy to use and provides a high-voltage barrier to protect against surges, noise, and ground loop errors.

Digital I/O

These digital I/O modules interface on/off, hi/lo, or open/close discrete logic devices and relays to a control network.

BusWorks 900EN Series
Digital I/O
Digital I/O modules monitors and/or controls up to 16 devices per unit. These units provide an isolated interface for discrete I/O signals. Outputs provide on/off, high/low, or open/close device control. Inputs sense the level/status of motors, valves and other equipment.

♦ Bi-directional I/O controls and verifies level in one unit
♦ Selectable failsafe modes
♦ Pulse counting capability with non-volatile memory
