VEGAMET 861 Controller for one 4-20mA/HART sensor input (With ATEX intrinsically safe sensor supply)

1 x 4-20 mA sensor input, 1 x 4-20 mA current output, 4 x operating relay (1 of which can be used as a fail-safe relay).

ATEX/UKEX approved for installation in an Ex-free area but with intrinsically safe sensor supply. Appropriate sensor can be installed Zone 0, 1, 2 (Class I Division 1, 2)

The VEGAMET 861 controller feeds a connected 4- 20 mA sensor, processes the measured values and displays them.

A large display for data visualisation is integrated in the housing designed for rough field conditions.

With a VEGAMET 861, tank level readings can be reliably monitored and displayed as level, volume and/or percentage full, and 1amp relays can be switched based on tank levels, e.g. for overfill protection alarm activation or pump/valve activation.

Integrated Bluetooth technology means the controller can be programmed, commissioned and troubleshooted quickly and easily via the free VEGATOOLS smartphone/tablet app or using a Bluetooth enabled PC with free VEGA software.
