PECIFICATIONS
General
– for the Mother Board
Signal Logic Level:
Automatically supports either 5V or 3.3V CPCI bus
Power (Motherboard):
+5 VDC @ 750mA and ±12V @ 15mA, then add pwer for each individual
module
Temperature, Operating:
“C” =0°C to +70°C; “E” =-40°C to +85°C (See part number
)
Storage Temperature:
-55°C to +105°C
Size:
Height -
3.94” / 100 mm (3U)
Width -
0.8” / 20.3 mm (4HP)
Depth
– 6.3” / 160 mm
Weight:
4 oz. (115 g) unpopulated,
Add weight for each module (typically 1 oz. each)
Add 2oz. (57g) for reference supply
Add 2 oz. (57g) for wedgelocks
D/S (Module 3*, 4*)
– One Isolated Digital-to-SYN/RSL Ch, 3.0 VA Output
*See P/N
(Applies to each channel unless noted otherwise)
Resolution:
16 bits (.0055°)
Accuracy:
0.067º (4 arc minutes) for passive loads; 30 arc minutes for TR’s
Output Format:
Synchro or Resolver, (see part number), galvanic isolation
Output Voltage:
(See code table and part number)
Output Load:
3.0 VA max. /Channel. Short circuit protected
Output Control:
Channel output can be turned ON/OFF
Regulation (VL-L):
5% max. No load to Full load
Rotation:
Continuous rotation or programmable Start and Stop angles. 0 to
13.6 RPS with a
resolution of 0.15
/sec. Step size is 16 bits (0.0055)° up to 1.5 RPS, then linearly
increases to 12 bits (0.088°) at 13.6 RPS
Reference Input Voltage:
2 to 115Vrms, Galvanic isolated. Uses @ 1 ma max/Channel
Reference Frequency:
47 Hz to 10 KHz (See part number)
Phase Shift:
0.5° max. (Between output and reference)
Programmable Phase Shift:
Programmable, ± 90
with 0.1
resolution
Settling Time:
Less than 100 microseconds
Module Power:
+5VDC @ 50 mA
±12VDC @ 115 mA (no-load); (Add 1.1 watts of ±12V for every VA of output).
Therefore, a 3.0 VA Load adds to ±12VDC 138 mA average, or 157 mA peak
External ±12VDC input power can be utilized
Ground:
Isolated signal and reference. Channels individually isolated from each other and
from system ground
Weight:
1.5 oz. (42g)
D/S (Module 1*,2*)
– Two Isolated Digital-to-SYN/RSL Ch, 1.5/2.2 VA Outputs
*See P/N
(Applies to each channel unless noted otherwise)
Resolution:
16 bits (.0055°)
Accuracy:
±1 arc-minute (.017°) from No Load to Full Load
Output Format:
Synchro or Resolver (see part number), galvanic isolation
Output Voltage:
(See code table and part number)
Output Load:
1.5 VA @ 11.8 VLL or 28 VLL, and 2.2 VA @ 90 VLL max. per Channel
(Power reduces linearly as output voltage is reduced.) Shortcut circuit protected
Output Control:
Module outputs can be turned ON/OFF
Regulation (VL-L):
5% max. No load to Full load
