MTL5546Y MTL Isolating Driver for 4-20mA HART valve positioners with line fault detection
The MTL5546Y-T accepts a 4/20mA floating signal from a safe-area controller to drive a current/pressure converter (or any other load up to 800Ω) in a hazardous area. For HART valve positioners, the module also permits bi-directional transmission of digital communication signals. Process controllers with a readback facility can detect open circuit in the field wiring: if this occurs, the current taken into the terminals drops to a preset level.
