Universal interfacing device, 4-character current/voltage displays and meter/totaliser with additional functions and external power supply.

The AMS400A interfacing devices are used between the control unit and field devices.
It carries out the manual simulation of automatically controlled loops. Typical applications are manual start-up of sensitive processes before handover to automatic control and manual override in case of controller failure or malfunction.

The current/voltage displays of the PMX420 series are available as a pure PMX420 display unit and optionally with analogue outputs or four alarm outputs


The basic model is suitable for displaying all standardised current or voltage signals.

The programmable meter components from the PTX800A are for measuring flow quantity:
they process standardised analogue current and voltage signals. Linearisation and interference-suppression functions are available for processing measurement signals. In addition, the meters have a 24 VDC power supply for external loop-powered sensors.
