KBRG SI-4X Bipolar Signal Isolator Board for KB Electronics Models KBRG-240D, KBRG-225D, KBRG-212D and KBRG-225 Regenerative Drives.
KBRG SI-4X Bi-Polar Signal Isolator is designed to provide input signal isolation for regenerative drive models when used with nonisolated input voltage following signal sources.
This unit is easy to install, and is equipped with multiturn "zero" and "max" trimpots.
It contains a jumper selection for input voltage range (0 to ± 25, 0 to ± 250 VDC) and isolated enable circuit. The isolator is especially useful when connecting a programmable controller or process controller with analog output card to the KBRG.
A separate power supply is not required since the SI-4X contains a built-in supply. The SI-4X is factory calibrated so that a 0 to ± 10 VDC input signal will provide 0 to ± 110% of motor speed.
