Specifications :


Type High intensity transflective numeric and alphanumeric LCD, UV-resistant, with bright backlight. Intensity can be adjusted via the keypad.
Note When battery powered, the backlight is only operational after a keypad touch, to extend battery lifetime.
Dimensions Ø 65 x 45mm (2.56” x 1.77”)
Digits Seven 12mm (0.47”) and eleven 7mm (0.28”) digits. Various symbols and measuring units.
Refresh rate User definable: 8 times/sec. – 30 secs
Speedometer To indicate the actual flow rate the bargraph runs from 0 to 100% in 20 blocks, each block is 5%

-Operating Temperature

Ambient -40°C to +70°C (-40°F to +158°F)

Power Requirements

Type PB Long life Lithium battery – lifetime depends upon settings and configuration – up to approx. 3 years
Note PB The battery can power the backlight for a short time after a keypad touch but cannot power the relay output (OR) or the real sensor supply (Terminal P3)
Type PD 9 – 27V DC. Consumption max. 4.5 Watt
Type PX 9 – 27V DC. Consumption max. 3 Watt
Type AH Loop powered, analog output. 11 – 27V DC, Min. 3.5mA. Consumption max. 675mW (25mA @ 27VDC)
Note AH The loop powered analog output cannot power the backlight, mechanical relay output (OR) or the real sensor supply (Terminal P3)

-Sensor Excitation

Type AH/PB/PX Terminal S3: 3V DC for pulse signals and 1.2V DC for coil pick-up, Iout max. 100μA
Note AH/PB/PX This is not a real sensor supply. Only suitable for sensors with a very low power consumption like coils (sine wave) and reed-switches
Type PD Terminal P3: 8.2 / 12 / 24V DC 8.2V DC, Iout max. 20mA 12V DC, Iout max. 30mA 24V DC, Iout max. 75mA (this voltage varies depending on the input supply voltage)

-Terminal Connections

Type Removable plug-in terminal strip. Wire max. 1.5mm2 and 2.5mm2

-Data Protection

Type EEPROM backup of all settings. Backup of running totals every minute. Data retention at least 10 years.
Password Configuration settings and clear total can be password protected.
