MEASURING AMPLIFIER Via Monginevro 262/7, 10142 Torino, ITALY Tel +39 011 5360884 - FAX +39 011 19835705 E-Mail: info@asa-rt.com http://www.asa-rt.com ADS-R Technical datasheet CANopen Dimensions in mm ADS-R is a digital measuring amplifier for strain gauges bridge, including a 24 bit acquisition circuit with programmable gain and 3 analog outputs towards a supervision unit. In the standard mode, the measuring amplifier allows the analog signal zeroing (calibration), and the output gain increasing / decreasing, by a three-buttons interface; the output tension is continuously visualised on the display, allowing, therefore, the adjustment without external instruments (tester or screw-driver). In the advanced mode, it is possible to program all operational parameters of the units, by the keyboard and the display: zero, gain (full scale in engineering unit), pass-band of the filter on the signal etc.; in normal operation, the display visualises the tension measurement, calculated according to the current parameters. The ADS-R is also available with an RS485 interface, a CANopen DS404 interface, a Profibus DPv1 interface or a Profinet I/O interface TECHNICAL CHARACTERISTICS - External power supply 24VDC ± 10% / 0.2A - Interface for strain gauges bridge, characterised by: bridge supply 5 VDC - 60 mA total (4 load cells 350 Ohm in parallel). acquisition with a 24 bit ADC converter. linearity 0,05% F.S. thermal drift 0,001% F.S. / ° C independent sense wires. - N. 2 analog outputs ± 10 VDC, Ro > 2 KOhm. - N. 1 analog output 4..20 mA , Ro < 150 Ohm. - N. 2 opto-isolated digital inputs 24 VDC (positive logic). - N. 2 opto-isolated digital outputs 24 VDC / 50 mA (positive logic). - 5-digits display indicating the measured value (from +9999 to -9999). - Key for zeroing the measured value / enter for the value in edit. - Key for gain increasing / increasing digit for the value in edit. - Key for gain decreasing / decreasing digit for the value in edit. - Key for entering parametrization / abort for the value in edit. - Key for selecting the digit in edit. - Assembling on DIN guide step 23 mm (standard solution) or 35 mm (with expansion card). - RS 485 optional expansion card. - Profibus DPv1 optional expansion card. - CANopen DS404 optional expansion card. - Profinet I/O optional expansion card with integrated 2-ports switch.
