| PCLD-780 PCLD-880 Screw Terminal Board with Flat Cables Wiring Terminal Board with Flat Cables and Adapter Features Pin to pin design Low-cost universal screw-terminal boards for industrial applications 40 terminal points for two 20-pin flat cable connector ports Reserved space for signal-conditioning circuits such as low-pass filter, voltage attenuator and current-to-voltage conversion Table-top mounting using nylon standoffs. Screws and washers provided for panel or wall mounting PCLD-780 Only Screw-clamp terminal-blocks allow easy and reliable connections Dimensions: 102 x 114 mm (4.0" x 4.5") PCLD-880 Only Supports PC-LabCardTM products with DB37 connectors Industrial-grade terminal blocks (barrier-strip) permit heavy-duty and reliable connections Dimensions: 221 x 115 mm (8.7" x 4.5") PCLD-780 PCLD-880 Introduction PCLD-780 and PCLD-880 universal screw-terminal boards provide convenient and reliable signal wiring for PC-LabCardTM products with 20-pin flat-cable connectors. PCLD-880 is also equipped with a DB37 connector to support PC-LabCardTM products with DB37 connectors. PCLD-780 and PCLD-880 let you install passive components on the special PCB layout to construct your own signal-conditioning circuits. You can easily construct a low-pass filter, attenuator or current-to-voltage converter by adding resistors and capacitors onto the board's circuit pads. Applications Field wiring for analog and digital I/O channels of PC-LabCardTM products which employ the standard 20-pin flat cable connectors or DB37 connectors (only PCLD-880) Signal conditioning circuits can be implemented as illustrated in the following examples: a) Straight-through connection (factory setting) RAn = 0 jumper d) 4 ~ 20 mA to 1 ~ 5 VDC signal converter RAn = 0 (short) RBn = 250 (0.1% precision resistor) Cn = none Pin Assignments RBn = none Cn = none b) 1.6 kHz (3dB) low pass filter RAn=10K RBn=none Cn=0.01F f3dB = c) 10 : 1 voltage attenuator RAn = 9 K RBn = 1 K Cn = none Attenuation = (Assume source impedance << 10 K) Ordering Information PCLD-780 PCLD-880 PCL-10137-1 PCL-10137-2 PCL-10137-3 PCL-10120-1 PCL-10120-2 Screw Terminal Board w/ Two 20-pin Flat Cables Wiring Board w/ Two 20-pin Flat Cables & Adapter DB37 Cable, 1 m DB37 Cable, 2 m DB37 Cable, 3 m 20-pin Flat Cable, 1 m 20-pin Flat Cable, 2 m Online Download www.advantech.com/products |
