Voltage Repeater
Description
This isolated barrier is used for intrinsic safety applications. 1-channel isolated barrier, 24 V DC supply (Power Rail), Voltage input 0 mV .. ± 500 mV, Voltage output 0 mV .. ± 500 mV, Selectable up/downscale sensor breakage detection, Transfer direction: to the control systempa. It transfers low voltage signals from load cells, strain gauges, operational amplifiers, and inductive oscillation sensors located in hazardous areas to safe areas. The input voltage of the terminals 4 and 5 is transferred to the terminals 7 and 8. The input, output, and power supply are galvanically isolated from each other. Upscale or downscale lead breakage monitoring is selectable via switches located on the front panel of the device. Note:. This unit requires three minutes after power-up to reach the accuracy cited in the technical data.
