PCI-7250/7251 8/16/24/32 Channels & Isolated Digital Input Cards Features 32-bit PCI bus, plug and play 8 Relay actuator outputs 8 Photo-isolated digital inputs LED indicate the energized relay On-board relay driving circuits Jumper Selectable for AC/DC isolated input On-board digital input signal conditioning  circuits Extendable to 32 Relay & 32 DI card with three  PCI-7251 boards

PCI-7251 / 8 Relay and 8 DI Extension Card   The PCI-7251 is an 8 Relays & 8 isolated DI extended board for PCI-7250. All the I/O functions of PCI-7251 are the same as PCI-7250, but the PCI-7251 must be connected with PCI-7250 and the bus interface is controlled by PCI-7250. Up to 3 PCI-7251 boards can be connected to one PCI-7250, therefore, extends the PCI-7250's DIO from 8 DIO to 16/24/ 32 DIO.   Specifications Relay Output Numbers of relay: 8 Relay type: Single-pole double-throw (SPDT) Output channels (SPDT): - Relay # 0~3 are Form C (includes normal open and close contacts) - Relay # 4~7 are Form A (includes normal open only) LED indicates each relay's ON/OFF status for monitoring. Contact Type: 120VAC @ 0.5A or 24VDC @ 1A Contact resistance: Bifurcated Relay ON/OFF time: 5 ms typical Coil voltage: +12V @ 33mA for each relay Isolated Inputs Number of channels: 8 Photo isolators: PC-814 Input signal type: AC or DC - AC: don't care polarity - DC: with polarity Input voltage: 5 ~ 24VDC or AC 50 ~ 1,000Hz Input filters: RC low pass filter Input impedance: 1.2 KW Isolation voltage: 5,000 V rms channel-to-channel and/or channel-to-ground Response time: - 20 m sec without AC Filter - 2.2 ms with AC Filter     General Specifications Operating temperature: 0°~ 60°C Storage temperature: -20°~ 80°C Humidity: 5~90%, non-condensing Power consumption: PCI-7250: +5VDC: 120mA typical PCI-7251: +5VDC: 110mA typical PCB dimensions: - PCI-7250: 162 mm x 102 mm - PCI-7250: 141 mm x 101 mm Software Support PCI-7250Library &Utility for DOS library and Windows 95 DLL, shipped with card PCIS-DASK/NT [/98] are the data acquisition software kits for Windows NT or 98.
