Analog load cell transmitter SCT-1100

digital

Overview
The SCT-1100 is a compact signal conditioning transmitter for up to four load cell inputs. It can operate as independent or dependent four-channel weight transmitters to provide direct net, gross and tare readings for industrial weighing applications. DIN-rail mounting and a red LED display make it suitable for control panels and machine enclosures.
