Reserved space for signal-conditioning circuits such as low-pass filter, voltage attenuator and current shunt. Industrial-grade screw-clamp terminal blocks for heavy-duty and reliable connections. PCLD-8115 only Supports PCL-818 series multifunction cards Nylon standoffs, screws and washers included for easy mounting Dimensions (W x L): 169 x 112 mm (6.7" x 4.4" ) PCLD-8710 only PCLD-8710 Supports PCI-1710/1710L/1710HG/1710HGL/1711/1711L/1716/1716L cards DIN-rail mounting case for easy mounting Dimensions (W x L x H): 169 x 112 x 51 mm (6.7" x 4.4" x 2.0") PCLD-8115 Introduction The PCLD-8115 screw-terminal board offers convenient and reliable signal wiring for multifunction cards with 20-pin flat cable connectors or DB37 connectors, such as the PCL-818 series cards. PCLD-8710 is designed to match multifunction cards with 68-pin SCSI-II connectors, such as the PCI-1710/1710L/1710HG/1710HGL/1711/1711L/1716/1716L cards. This screw-terminal board also includes cold junction sensing circuitry that allows direct measurements from thermocouple transducers. Together with software compensation and linearization, every thermocouple type can be accommodated. Due to its special PCB layout, you can install passive components to construct your own signal-conditioning circuits. So you can easily construct a low-pass filter, attenuator or current shunt converter by adding resistors and capacitors onto the board circuit pads. Applications Field wiring for analog and digital I/O channels of PC-LabCard™ products. Signal conditioning circuits can be implemented as illustrated in the following examples: a) Straight-through connection (factory setting) RAn = 0 Ω (short) RBn = none Cn = none c) 10 : 1 voltage attenuator: RAn = 9 KΩ RBn = 1 KΩ Cn = none Attenuation = (Assume source impedance << 10 KΩ) d) 4 ~ 20 mA to 1 ~ 5 VDC signal converter: RAn = 0 Ω (short) RBn = 250 Ω (0.1% precision resistor) Cn = none Ordering Information PCLD-8115 PCLD-8710 PCL-10137-1 PCL-10137-2 PCL-10137-3 PCL-10168-1 b) 1.6 kHz (3 dB) low pass filter RAn = 10 KΩ RBn = none Cn = 0.01 μF PCL-10168-2 f3dB = Industrial Wiring Terminal Board with CJC circuit and DB37 cable assembly Industrial Wiring Terminal Board with CJC circuit for DIN-rail mounting (cable not included) DB37 cable assembly, 1 m DB37 cable assembly, 2 m DB37 cable assembly, 3 m 68-pin SCSI-II cable with special shielding for noise reduction, 1 m 68-pin SCSI-II cable with special shielding for noise reduction, 2 m Online Download www.advantech.com/products Terminal Board Dimensions PCLD-780 5.0mm 93.25mm PCLD-782 5.0mm 5mm D=4.5mmX4 m 5mm 205mm 5 5.0mm 5.0mm 5mm PCLD-782B D=3.0mmX4 1 m 104.25mm 107mm D=5.0mmX4 m 5mm 5 210 mm 5 mm 5.0mm 5.0mm 5 mm 5.0mm PCLD-785 5 mm 5 mm 5 mm 210 mm PCLD-786 5 mm 5 5 m m 220 mm PCLD-785B 5mm 5.0mm D=5.0mmX4 D=5.0mmX4 105 m m m 122 107 m m D=3.0mmX4 5 5 195mm 5mm PCLD-789D PCLD-880 5mm 5mm PCLD-788 5mm 9.7mm 9.7mm 203.23mm 9. 9 D=5.0mmX4 D=4.0mmX4 1 105mm 105mm m m D=4.5mmX4 m 5mm 5mm PCLD-885 5mm PCLD-7216 5.0mm 5.5mm 97.25mm 5.0mm 6 5.0mm 345.77mm 6. 5mm PCLD-8115 5mm 7.2mm m D=4.5mmX4 D=5.0mmX4 m D=5.0mmX4 9.7mm 9.7mm 5mm 5.0mm 205mm 195mm 5mm m m 5mm 9 9 195mm 5mm 6 m m 5.5mm 5.0mm 5.0mm 5mm 104.25mm m 106mm 7 6. 7.2mm 5.0mm Online Download www.advantech.com/products 5.0mm
