The SI-4X provides complete electrical isolation between input voltage signals which are derived from programmable controllers, transducers and digital/analog converters and the KBRG. The Module contains two input ranges (±25, ±250 VDC) which are jumper selectable. The input/output ratio can be scaled via the included “ZERO” and “MAX” trimpots. The SI-4X installs easily onto the KBRG chassis.
