PRODIS-TDC Digital Process Meter for Time-of-Flight Sensors · For Sensors with pulse output: · Automatic sensor parameter upload at power-on – no calibration necessary · Integrated sensor supply · 6-digit LED display · RS-232 interface · Optional 4 comparator outputs · Easy programming Description PRODIS-TDC displays measurement values of magnetostrictive position sensors, programmable scaling is provided to display units like mm or inch. The request signal will be sent to the sensor periodically. The time between the start pulse and the stop pulse will be counted by a high-resolution time-digital-converter (TDC). When used with POSICHRON sensors the calibration parameters of the sensor will be uploaded to the meter at power-on. This avoids a calibration when the sensor has been changed. A tare function or programming lock can be activated with two control terminals. Sensor excitation is supplied from the meter. Optional comparator functions with 4 NPN open-collector outputs are available, additional 2 of them have relay output.

The position sensor responds with a START and a STOP signal. Position value x = t(x) · vs To calculate the position value the time interval t(x) must be multiplicated with the conversion factor vs on the type label. When ASM POSICHRONâ sensors are used the conversion factor vs will be uploaded at power-on. 52 CAT-PC-E-04 Tel.: +49-8123-986-0 Fax: +49-8123-986-500 www.asm-sensor.com ASM GmbH PRODIS-TDC Digital Process Meter for Time-of-Flight Sensors Outline drawing LED1 LED2 Control panel cutout acc. to DIN 43700 PD - TDC - 24VDC PD - TDC - 230VAC Dimensions informative only For guaranteed dimensions consult factory!
