Digital Epic D460/D470 Control Transmitter
Brand: Westlock
Discrete position control and precision, non-contact position feedback with digital communication via HART protocol in an explosionproof, integrated package.
With options for linear or rotary control valves and remote PST/ESD initiation.
Features- Microprocessor based technology allows digital communication via HART protocol
- Remote and local partial stroke test (PST) and emergency shut down (ESD) initiated remotely via HART signal for safety system applications
- Valve position measurement via a non-contact magnetic pick-up eliminates mechanical drive arms or linkages increasing reliability in high cycle applications or where vibration is present
- Highly visible position indicator
- Available with low power Falcon solenoid valve
- Solenoid coils integrated within enclosure
- Choice of factory pre-wired 3 and 4 way Falcon solenoid valves
- Solenoid valves with a choice of Cv ratings and coil voltage
- Model D460 features a low copper aluminum enclosure with powder coat finish
- Model D470 features a heavy duty stainless steel enclosure
