Description –

The Data Handler (DH) at the local site accepts a 4/20 mADC tank level signal and compares it to internal turn on and turn off setpoints. The DH, in turn, transmits pump on and off commands to the remote site DH via the Spread Spectrum Radios (SSR). The remote DH converts those commands to contact outputs for operating the motor starter. The remote site DH accepts one 4/20 mADC pump flow signal and pump running contacts and transmits them to the local site and converts them back to 4/20 mADC and contact closure for local display and recording. The local site DH closes a contact in the event there is a communications failure.
