| BJ\P VD4 MICROPROCESSOR DIGITAL READOUTS VD4 microprocessor panel readouts can read either analogue or digital signals. The following versions are available: | |||||||||||||||||||||||||||||||||||||||||||||
| Vcc One voltage input channel. Input range: ± 2 Vdc, ± 20 Vdc, ± 200 Vdc Vcc2R One voltage input channel and 2 relay outputs Lq Input by potentiometer with resistance 1 t 20 KOhm Lq2R Input by potentiometer and 2 relay outputs Icc One direct current input channel. Input range ±20mA, ±200mA, ±2A (Configured at factory) Icc2R One direct current input channel and 2 relay outputs Ica2R One alternate current input channel. Input range: 2A. 2 relay outputs F Tachometer with digital input. Max Frequency 10 KHz | |||||||||||||||||||||||||||||||||||||||||||||
| To allow the best visibility in any environmental condition, the values of the process variable are displayed on four 12.7 mm 7-segment red displays. The readout versions named with suffix 2R have two comparing alarms on the displayed variable. Each of them can be configured for > or < and for excitation type: steady or pulse one with settable time. The polyester flat keypad is used to enter the presets and the instrument set-up. The user friendly interface simplifies the daily use of the instrument, as well as the installing operation. A password protects the set-up phase from accidental accesses. Thanks to the excellent price/performance rate featuring this instrument series, VD4 readouts can be used for all those applications where visualization and control must be performed at a contained price level.Complying with C€ standard. | |||||||||||||||||||||||||||||||||||||||||||||
