CALOG INSTRUMENT’s versatile CALOG by INSTROTECH DPM9000 series – a miniature DIN-rail mount programmable isolated transmitter range – has consistently sold well into the market, partly due to its reliability and partly to the versatile wide range of programmable inputs. With dimensions of 92 x 92 x 26mm, the CALOG by INSTROTECH DPM9000 series is definitely a space-saver. Configuration and field calibration is done via any Windows based computer or tablet, running the user-friendly SmartView® software, available for download on the Instrotech website (http://www.instrotech.co.za/Media-Downloads/Software).
The model DPM9000 transmitter offers complete 3-way isolation between power supply, input and output. The inputs are programmable to accept thermocouples of type J, K, N, R, S, T & W5, RTD’s of type Pt100 or Ni100, mV inputs up to 52mV, 0-20mA / 4-20mA inputs, volt inputs up to 10V, potentiometer inputs, and frequency inputs from NPN / PNP proximity switches.
Integral 2-wire transmitter power is supplied as standard with the units, as well as a precision reference for potentiometer inputs. The analogue output is programmable for 0-20mA / 4-20mA or 0-10V outputs. The power supply comes standard as 95-265V AC/DC as well as the RS-232 serial. The serial interface allows connections to remote computers and SCADA systems using Calog’s DIGIbus protocol. The RS-485 option allows for up to 99 transmitters to be linked on the same bus. The unit can also accept an ASCII based serial input signal for conversion to an analogue output signal. The linearizer feature is standard and the user can select s-curve, sphere, square-root extraction or off (no linearization)
The model DPM9240 offers a 10 – 30 VDC isolated power supply instead of 95-265V AC/DC.
Also available in the series are the Models DPM9004, 95 – 265 VAC/DC supply, and the DPM9244, 10 – 30 VDC supply, ideal for load cell applications. The model DPM9006 is a High Current (0 – 5A) or High Voltage (0 – 500 VAC/DC) input version.
All units meet the European EMC directive 89/336/EEC & Low Voltage directive 73/23/EEC.
Locally designed and manufactured by CALOG INSTRUMENTS, the DPM9000 series forms part of their extensive range of high quality process control instrumentation.
