32-channel Isolated Digital I/O PCI-1750 and Counter Card Features • 16 isolated DI and 16 isolated DO channels • High voltage isolation on all isolated channels (2500 VDC) • High sink current on isolated output channels (200 mA/channel) DC • Supports dry contact or 5 ~ 48 V isolated inputs • Interrupt handling • Timer/Counter interrupt capability Introduction • Input range: 5 ~ 48 VDC or dry contact The PCI-1750 card offers 16 isolated digital input channels, 16 isolated digital output channels, and one isolated counter/timer for • Isolation voltage: 2,500 VDC the PCI bus. With isolation protection of 2,500 VDC, and dry contact • Throughput: 10 kHz support, the PCI-1750 is ideal for industrial applications where high- voltage protection is required. Digital Output Each I/O channel of the PCI-1750 corresponds to a bit in a PC I/O • 16 Optically-isolated outputs port. This makes the PCI-1750 very easy to program. This card also • Output range: Open collector 5 ~ 40 VDC offers a counter or timer interrupt and two digital input interrupt lines • Sink Current: 200 mA max. per channel to a PC. Users can easily configure them through software. • Isolation voltage: 2,500 VDC • Throughput: 10 kHz PCI-Bus Plug and Play The PCI-1750 uses a PCI controller to interface the card to the PCI Programmable Counter/Timer bus. The controller fully implements PCI bus specification Rev 2.1. • One 32-bit timer All bus relative configurations, such as base address and interrupt • One 16-bit optically-isolated counter assignment, are automatically controlled by the software. No jumper - Shares pin with isolated input 15 or DIP switch is required for user configuration. - Throughput: 1 MHz max. On-board Programmable Counter/Timer - Isolation voltage: 2,500 VDC The PCI-1750 provides a programmable counter/timer for generating General periodic interrupts to the host computer. The counter/timer chip is • Interrupt source: Isolated input 0, 8, counter and timer an 82C54, which includes three 16-bit counters based on a 10 MHz clock. One counter is used to count events coming from the isolated • Power consumption: 5 V @ 850 mA (typical) input channel. The other two are cascaded together to make a 32-bit 5 V @ 1.0 A (max.) timer. • Operating temperature: 0 ~ +70° C (32 ~ 158° F) • Storage temperature: -20 ~ +80° C (-4 ~ 176° F) Applications • Operating humidity: 5 ~ 95% RH non-condensing (refer to IEC 68-2-3) • Industrial ON/OFF control • Connectors: One 37-pin D-type female connector • Contact closure monitoring One 2-pin terminal block for extended ground • Switch status sensing • Dimensions: 175 mm (L) x 100 mm (H) (6.9" x 3.9") • BCD interfacing • Digital I/O control Ordering Information • Industrial and lab automation PCI-1750: 32-channel isolated DIO and counter card Specifications PCL-10137: DB-37 cable assembly, 1 m ADAM-3937: 37-pin D-type cable wiring terminal for DIN-rail Digital Input mounting • 16 Optically-isolated inputs PCLS-OCX: ActiveX control for data acquisition and control DA&C Series 7-40
