A panel mountable unit for display of standard electrical signals used in measurement and control engineering applications.

The units are available as either models ZA (3½-digit) or ZB, ZP (4½-digit) and comply with standard mounting dimensions 96 x 48 mm.  They are both fitted with 14mm high red LED displays and are accurate to 0.1% of the effective range limit.  The display value is easily set using the two-point method, by applying respective measurement signals and setting the required display variable. The use of various supply voltages and optional  sensor supply contribute to the universal applicability of the display units.  While in the ZA and ZB models, the setting potentiometer is located safely behind the protective front panel away from unauthorized access, the model ZP can be digitally programmed at the front using a disconnectable keypad and also equipped with up to a maximum of 4 relay contacts and an analogue output or digital serial interface.

The digital display units of the 1275 series are used in mechanical installations, as evaluating units for pressure gauges and temperature monitoring devices, as indicators for flow meters or to display electrical signals of the kind supplied by all GEMÜ sensors and pick-ups.

They are used as units for measured value acquisition for computers.  The a precision display in any required unit of measurement, simple limiting value adjustment and range of useful options, these digital indicator models provide an invaluable aid to operating staff.

Type 1275/000/ZA and ZB (Basic configuration)

Type 1275/000/ZP (Multi-function display)

The E-module 1572 provides a power supply for d.c. actuators with integral motor protection from a specified a.c. voltage.

The E-module converts an a.c. voltage to a 20 V pulsed unidirectional voltage.

An external switch can be used to reverse the voltage polarity and hence the direction of rotation of d.c. actuators.

The respective end positions of the actuator, "open" or "closed" are indicated by LED’s (green LED or red LED).  The power supply is indicated by a yellow LED.

In parallel with the programmable outputs, an additional unsmoothed 20 V d.c. terminal is available (e.g. the pilot conductor for E-module 1570).

The voltage transformer is built into a universally compatible housing which is designed for panel mounting or direct attachment to the respective GEMÜ actuator.

The output voltage is protected by a 1.6 A fuse.

Voltage: 24 V d.c.
Permissible voltage variation: ± 10%
Power consumption: 2W
N.B.: A charging period of at least 16 h is required before putting the unit into service

Max. input/output loading:   24V d.c., 4A
Output voltage:  UB16.5 V d.c.
Capacity: 110 mA/h
Internal fuse: M 4/250 V
Weight: 410 g  (.90 lbs.)
Cable gland: PG 13.5

Temperature transducer in an all-plastic housing with Pt 100 resistance sensor for temperature measurements for 0-100° C (0-212°F).

The temperature transducer type 3220 converts to the physical variable temperature proportionally into an electrical signal.  It is available in the form of a two-wire transducer (4-20 mA) and as a temperature measuring instrument with an optional power (0/4 – 20 mA) or relay output (MIN and MAX switching points).

The process connection is configured as standard with male threads, to DIN 3852 in sizes G 1/2 A and G 3/4A.

Electrical connections are effected using an electrical plug in compliance with DIN 43650, PG 11.

The transducer can be mounted in any position.

After screwing in the connecting element, the upper part of the housing can be turned up to ±180° to the required position by releasing the fastening screws.

Components coming into contact with the medium are made of PVDF or stainless steel, the housing is made of ABS and the seal of FPM.  Other seal materials are available on request.
