Displays are used in industrial and process automation for the visual display of data or for the analogue presentation of electrical and non-electrical measurement values. They are an important tool for user prompting, diagnostics and logging when operating machines and systems. Displays support dialogue-based operation, display measured values and fault reports, and are used to monitor processes.
Features, such as the internal calculation of process variables, digital and analogue outputs or interference suppression functions upgrade simple displays to high-quality process interfaces which can independently control sub-processes .
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.
3 1/2-character digital displays with an auxiliary power supply in the 1/8 DIN IP 65 housing for installation in the control panel. The DI350 is an inexpensive digital display for analogue current and voltage signals in industrial applications. With this display, analogue signals can be displayed universally from 4 to 20 mA or from 0 to 10 V. An integrated regulated power supply can supply two-wire measuring transducers connected on the input side.
3½- and 4½-character digital displays in loop-powered (two-wire) design for current-loop signals and 3½- character digital displays with auxiliary power supply in 1/8 DIN IP65 housing for installation in the control panel.
The LPD350 is a compact, cost-effective, 3½-character LCD digital display designed specifically for current loop signals.
The LDP450F comes with IP67 protection and is thus suitable for mounting in the field. The display is with equipped with a 4½-character LCD display that is easy to read even when poorly lit.
The DI350 is an inexpensive digital display for use in industrial applications with analogue current and voltage signals. With this display, analogue signals can be displayed from 4 to 20 mA or from 0 to 10 V. An integrated regulated power supply can be connected on the input side. This can be used to supply two-wire measuring transducers.
4-character temperature displays with optional additional functions and external power supply.
The PMX400 series offers high-quality 4-character LED displays in 1/8 DIN format with additional functions.
The displays can record temperature values from PT100 3-wire and thermocouples. On the output side, optional analogue signals are available, as well as either two or four relay contacts for limit-value monitoring.
An integrated power supply can be used for supplying external sensors and input devices. Displays from the PMX400 series are designed for control panel installation and feature IP65 protection.
Frequency meter and totaliser with additional functions and external power supply for installation in control panels.
The PMX400 series provide high-quality 4-character LED displays with additional features . A variety of frequency signals can be processed on the displays. On the output side, analogue signals are optionally available, as well as either two or four relay contacts for limit-value monitoring.
The programmable counter components of the PTX800 series with 8-bit digital display can process input-side TTL signals or, optionally, pulses from NAMUR and NPN/PNP sensors. Comprehensive linearisation and interference-suppression functions are available for processing measurement signals. On the output side, there is the option of a mA/V analogue signal and 2 CO contacts for limit-value monitoring.
Both counters offer 24-VDC voltage for supplying external two-wire sensors.
