Transcription

1 Configurable Analog Frequency Transducer INTERFACE Data Sheet PHOENIX CONTACT - 02/2006 Description The configurable analog frequency transducer MINI MCR-SL-UI-f(-SP) is used to convert analog standard signals to frequency signals or pulse width modulated (PWM) signals. On the input side, there are the analog signals 0 ma ma, 4 ma ma, 0 ma ma, 2 ma ma, 0 V V, 2 V V, 0 V... 5 V, or 1 V... 5 V. The DIP switches are accessible on the side of the housing and allow the following parameters to be configured: Input signal, Output signal, Output behavior with measuring range overrange or underrange, and Filter type (for smoothing interferences on the input signal). The voltage supply (19.2 V DC V DC) can be provided via connecting terminal blocks "3"/ "4" or "7"/ "8" of the modules, or together, via the DIN rail connector (see Figure 6 on page 6). Please also observe point "Power Supply" on page 7.. Make sure you always use the latest documentation.

5 Installation Screw Connection Spring-Cage Connection Figure 3 MINI MCR-SL-UI-f Figure 4 MINI MCR-SL-UI-f-SP The device may only be installed and put into operation by qualified personnel. The corresponding national regulations (e.g. VDE, DIN) must be observed. Notes for Ex: The device is category 3 electrical apparatus. Please observe the instructions given here for installation. The device must be installed in a housing with IP54 protection in acc. with EN The limits for mechanical or thermal loads described for the device must not be exceeded. Only devices designed for operation in the hazardous areas of Zone 2 may be connected. Under no circumstances may repairs be carried out by the user. Only engage or connect conductors in the hazardous area when the device is deenergized! The assignment of the connecting terminal blocks is shown in Figure 5.

6 Using DIN rail connector ME 6,2 TBUS-2 1,5/5-ST-3,81 GN (Order No.: ) Please also pay particular attention to the direction of the MINI Analog module and DIN rail connector when snapping into position: Snap-on foot (Figure 6, detail D 7) below and plug (Figure 6, detail C 11) left! First position the DIN rail connector in the DIN rail to bridge the voltage supply (see Figure 6).. Figure 6 Mounting/removing _02_en PHOENIX CONTACT 6

7 Power Supply Never connect the supply voltage directly to the DIN rail connector! It is not permitted to draw power from the DIN rail connector or from individual MINI Analog modules! Feeding in power via the MINI Analog module Where the total current consumption of the aligned MINI Analog modules does not exceed 400 ma, the power can be fed in directly at the connecting terminal blocks of a MINI Analog module. We recommend connecting a 400 ma fuse upstream. Feeding in power with a power terminal block Power terminal block MINI MCR-SL-PTB (Order No.: ) or MINI MCR-SL-PTB-SP (Order No.: ), of the same shape, is used to feed in the supply voltage to the DIN rail connector. We recommend connecting a 2 A fuse upstream. Feeding in the power with a system power supply unit System power supply unit MINI-SYS-PS-... (Order No.: ) with 1.5 A output current contacts the DIN rail connector with the supply voltage, allowing several MINI Analog modules to be supplied from the network. Configuration Electrostatic Discharge! The module contains components that can be damaged or destroyed by electrostatic discharge. When handling the module, observe the necessary safety precautions against electrostatic discharge (ESD), in accordance with EN and EN , as well as IEC and IEC At delivery, the modules are configured as follows: Input 0 V V Overrange: Freeze at 100% measuring range end value Underrange: Freeze at 100% measuring range start value Output: Frequency output 0 khz khz Moving Average Filter: 1 value Oversampling: 1 value (All DIP switches in the "off" position).

Analog IN 0 V V 1 V... 5 V 0 V... 5 V 2 V V 0 ma ma 4 ma ma 0 ma ma 2 ma ma The moving average filter can group values (1, 2, 4, 6) according to the bucket chain principle to form a new measured value. In the bucket chain procedure, the average of a fixed number of measured values is taken, whereby the oldest value is always dropped and the most recent added. 5 6 Moving Average Filter 1 value 2 values 4 values 6 values In order to smooth the measured values, an average can be formed from several measured values (1, 10, 50, 100) (Oversampling). DIP Switch S2 Using DIP switch S2 (see Figure 1, detail 9), you can set the output values and the overrange and underrange values.
