XR Series II: Controls
Standard Front Panel
XR models provide stepless analog control from front panel potentiometers. With a simple configuration change, the power supply can be programmed from the rear I/O connector or through software on one of the communications bus.
Computer Control - C Series
XR models utilizing the C Version front panel, XRC, only allow control from the rear connector or by RS232/GPIB/Ethernet communications. These models are intended for process control applications where front panel controls and displays are not required or desired.
Isolated External I/O for Automation
Using the rear 37-pin I/O connector, the XR Series power supplies can be completely controlled and monitored using external signals. The voltage, current, over voltage trip, and over current trip set points are set by applying a 0-10 Vdc signal. Each diagnostic condition is given a designated pin, which reads 10 Vdc when high. Also, the power supply features an external interlock, which when enabled, allows the power supply to be tied in with other emergency stop equipment. All these pins are isolated to earth-ground as standard--no additional isolation equipment necessary!
LXI-Certified Ethernet Option 
LXI is an instrumentation platform based on industry standard Ethernet technology designed to provide modularity, flexibility and performance to small- and medium-sized systems. LXI’s advantages are exemplified in its compact, flexible package providing high-speed I/O and reliable measurements. These features meet the needs of R&D and manufacturing engineers delivering electronics for the aerospace/defense, automotive, industrial, and medical markets.
Certified to the LXI Standard (Class C), the XR Series Ethernet option includes an embedded web-server, allowing web browser power supply control and monitoring from virtually anywhere.
