Ergonomics

With a comfortable keyboard, with large keys (22 x 22 mm), a clearly arranged display and the flexible functionality it is easy to realize simple as well as com- plex batch applications directly in hazardous area, without huge wiring expense to a e.g. panel room in safe area.

Simple remote control
It is possible to realize a remote control for the basic functions "START", "STOP", "RESET"

Process monitoring
The DC155 has a comfortable malfunction and disturbance monitoring system to monitor the sensor wiring and the flow.
To avoid wrong warnings, it is possible to turn off the monitoring for a programmable delay time at the start up phase. This is also possible for over or under-run of limit values.

Analog output
The analog output of the DC155 has a 14 bit resolution and it can drive an impedance up to 600 W, respectively 1000 W, using the separate analog output supply option.

MODBUS interface
With the modbus interface it is possible to view process data (like actual filled amout, total amount, etc) on a DCS for instance.
