Universal PCI, PCI-X, 3.3V and 5V compatible (Call for PCI-Express availability)
Watchdog timer to detect computer malfunction
Optional computer power supply monitor
Optional internal computer temperature monitor
Optional measurement of computer internal temperature
Optional fan-failure detection, watchdog time-out buzzer, and opto-isolated reset output
Time-out: Software selectable from 4 µSec to 2060 seconds.
Output Pulse Width: 16 mSec minimum.
Clock: 2.08333 MHz, derived from computer clock (33 MHz÷16).
Address: Continuously mappable within 000 to FFFF hex I/O range.
Relay Output: DPDT, Form C, max. switching current 2A DC at 30W or 1.25A AC at 30VA max.
Interrupt Output: PCI-INTA.
Status Monitor Options
Option 1: IRQ and status register indication if +5, +12, or -12 V exceed +/- 6% of nominal.
Option 2: Temp. Alarm IRQ and status register indication at 122o F and above.
Option 3: Temp. Measurement from A/D converter, LSB = 0.7o F (factory adjustable).
Option 4: Fan Speed: IRQ and status register indication whenever fan's tachometer output drops below 50pps (custom factory settings available). o Buzzer: Audio Alert signals watchdog timeout. Can be disabled by software. o LED Output: 5VDC, through 470 ohm resistor o Isolated Outputs: Complementary opto-isolated reset outputs (2). o Isolated Inputs: Two, opto-isolated, 5 mA typical load. Can be read at base address + 4. These bits generate Change-of-State IRQs.
Option 5: Replaces opto-isolated Reset outputs with computer generated digital outputs. The Buzzer does not function when this option is installed.
Option 6: Pulse-width modulates power to the fan to control fan speed. Speeds fan up when excessive internal computer temperature is sensed.
Operating Temperature Range: 0o to +60o C.
Storage Temperature Range: -50o to +120o C.
Humidity: 10% to 90% RH, non-condensing.
Power Required: +5 VDC at 125 mA with no options, 250 mA with all options installed.
