CPCI voltages; +5V, +3.3V, +12V, and –12V
Absolute Accuracy: ±2%
Sensor Semiconductor type, Range:
−
55 to 150°C,
Resolution: 0.03°C
Absolute Accuracy: ±2.5°C max, ±0.9°C typ over entire range.
Backplane One sensor located in the back cavity
Slots (only available on STLITE-CPCI-
16R+/8R+) One sensor positioned above each slot on a circuit card mounted
inside the chassis
Current Monitoring 15 mA < I < 450 mA, 6% absolute accuracy. Independent for left
and right-side fan pairs. Each fan pair protected with 500 mA
resetable fuse. Fan currents of 15 mA or less indicate an OFF or
OPEN condition.
Fan Tray Connector Each chassis includes a fan tray cable with Positronics
PLA03F0000 connector. Mates with Measurement Computing’s
optional STLITE-CPCI-FAN unit.
Timeout Jumper-selectable for 1, 10, and 30 seconds
Alarm Alarm outputs provide TTL, 500 mA current sink and
SPDT relay NO/NC/C pins.
