    INSTALLATION 3.1. Mounting / Fixing The Datalogger IDL 101 has a snap-on mounting for installation on standard profile rails 35 mm (1.4 inch) according to DIN EN 50022. The four straps on the backside of the module will perform the mounting on the DIN rail. First you push the two straps on the bottom behind the notch of the DIN rail and then you press the module on the DIN rail until the two straps on the top snap in.

    * The terminal designations A and B are exchanged, compared with the PROFIBUS-definitions, for all devices of the ISM series “100“ and the Datalogger IDL 101. This means that in multi-vendor-systems the bus lines A and B must be exchanged when they are connected to a device of the ISM-line or a Datalogger IDL 101.
  • Page 20: Connection Technique

    Figure 3.2 Connection of the distribution voltage Non-regulated DC voltage between +10 and +30 VDC is sufficient for the power supply of the Datalogger IDL 101 . The input is protected against excess voltage and current and against polarity conversion. The power consumption remains approximately constant over the total voltage range, due to the integrated switching regulator.

  • Page 42 IDL 101 FUNCTIONAL DESCRIPTION Notice: The Datalogger IDL 101 supports resistance measuring in 2 and 4-wire technique. With resistance measuring in 2-wire technique the supply lines cause an additional fall of potential, thus distorting the measuring result and influencing the measuring accuracy. Therefore it is necessary to pay attention specially with resistance measuring in 2- wire-technique to use as low-impedance leads as possible to the sensors and to make sure that the leads are well- connected with the data logger and the sensor.
  • Page 43 It can be measured and can be used for temperature measurement purposes. With the Datalogger IDL 101 the thermoelectric voltage is measured differentially. Since thermocouples can only measure a temperature difference (difference between temperature to be measured and temperature at the connecting terminals on the sensor module), a terminal temperature or a known temperature reference also have to be determined.
  • Page 44: Analog Output Channel

    0 and 10 V by means of the Configuration Software ICP 100. Via the analog output (AOut +, AGND) at the Datalogger IDL 101 actual measuring values or sensor variables can be output depending on the configuration. Thus for example it is possible to assign the value of a Setpoint Channel or the result of an Arithmetic Channel to the Analog Output Channel and to output them as analog set values.
  • Page 45: Digital Input Variable

    For the acquisition of digital status information (on/off, closed/open, left/right, etc.) the signal applied at the digital input is collected and is held ready for further processing in the Datalogger IDL 101 or for transmission via bus. The digital input is set (switch closed) as long as the applied signal voltage remains under the threshold value of 1.0 V.
  • Page 46 Notice: Frequency measurements can only be performed at the digital inputs I/O 01 to I/O 06 at 2000 Hz. As soon as more than 6 frequency measurements have to be realized, the high-end frequency is 100Hz. HB_IDL101_E_V222.doc Gantner Instruments Test & Measurement GmbH...
  • Page 47 When configuring a digital input as a progressive counter the Datalogger IDL 101 constantly monitors the digital input for a signal variation. If a negative signal edge (1 -> 0) occurs at the input, the current result is increased by 1.
  • Page 48: Digital Output Variable

    Via the digital inputs/outputs I/O 01 to I/O 16 on the Datalogger IDL 101 digital status information or measured quantities and sensor variables respectively can be output in digital form, according to the configuration. Digital status information can be withdrawn from the process (Process Out).

EN50081-1:92/-2:93 (interference emission) and EN50082-1:92/-2:95 (interference immunity) for industrial and residential areas. The stricter requirements have been applied. At present, further standards concerning CE-marking are not relevant for the IDL 101 . The IDL 101 is Labelled with the CE-Sign.
