USER MANUAL Option Boards PREFACE Option boards to customize your data logger Option boards can be used to add additional inputs/features to an ML-417 data logger or to perform signal conditioning. • Mechanically stack up to three option boards. • Maximum two similar boards, with a switch to choose a different CID.
1 Assembly The Option Boards have been designed to operate in conjunction with a ML-x17-xxx Data Logger. On the main PCB, there is a special “option port ” for supporting the various range of YDOC option Input /Output /Convertor boards.
USER MANUAL Option Boards Please note: Only one board of the ML-OI-AD-XXX family, may be present inside the Data Logger.

USER MANUAL Option Boards High Frequency mode Using high frequencies, be also sure to use the high frequency mode and to use a proper value for unit /pulse. Use 60 for rpm. Wiring The wiring of this board is very simple. Wire your sensor to X1.1 and X1.2. Connect a single wire between X1.3 and the digital input of your interest.
USER MANUAL Option Boards 8.1.6 Configuration The ML-OC-W2P needs no configuration. It is used as a convertor only. The converted signal must be applied to a regular digital input of the Data Logger. Manufacturers of low power instruments page 43...
USER MANUAL Option Boards 9 OP type Board Option Power Board. 9.1 ML-OP-524 9.1.1 Description ML-OP-524, to power external sensors or usable as standalone power supply. Power switches on in parallel with logger sensor power switch (internal control), from an external signal or continious. 9.1.2 CID CID Selector: 0x50 &...
USER MANUAL Option Boards 9.1.1 Connecting input power The ML-OP-524 converts the input power to a selectable output voltage. The power is taken from the batteries directly, so NOT loading the Data Logger. The 2 white connectors, shown in figure 2: 2, are connected in parallel.
USER MANUAL Option Boards More info Attention: when selecting 5 V, the output voltage is higher when no load is connected. Be aware of this phenomenon. The output voltage is exactly 5V, with a load, dissipating 1.5 mA or more. 9.1.6 Configuration The ML-OP-524 has no software settings, so it is NOT listed in the ML-x17 menu.
USER MANUAL Option Boards 9.1.7 Mode of operation There are 3 modes the board can operate with: - Internal operation - Standalone operation - Constant operation These different modes are selected by jumper(s) and explained below. Internal operation This mode is enabled when a jumper is installed on the location: “Internal”. This is the “normal” mode of operation.
Logger. The board is intended to be used with the YDOC Powerboard series (ML-PB-XX-XX). The board has NO fuse and is short circuit proof. In case of usage with the YDOC Power Boards, the fuse is already provided on the Power Board.

Now, you can setup the properties of the port. This is analogue to the settings of the normal analog ports of the Data Logger, with the addition of a selectable range. (Port Mode). Further information on this is found in the Data Logger Manual. (https://ydoc.biz/docs/ydoc-datalogger-manual/). Analog input...
To calibrate your board, follow the next section. Calibration Process To Calibrate your board, use two external resistors (or order them with YDOC, using Resistor 1k and Resistor 1k3). Goto the Analog Inputs menu and choose your sensor’s port. Then choose “[8] Determine linear conversion function (2 calibration points)”.

USER MANUAL Option Boards After this, the board is very accurate in measuring in both resistance and temperature. (<0.1%) Calibration of your board does NOT calibrate your sensor. Only the measured resistance is calibrated, but any deviation of R0 in your sensor in not eliminated. Manufacturers of low power instruments page 55...
