Ratio:
Dual speed, Programmable, Set any ratio between 2 and 255
Rotation:
Continuous rotation or programmable Start and Stop angles. 0 to 13.6 RPS with
a resolution of 0.015/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 isolation. 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 @ 570 mA ±12VDC @ 160 mA (no-load) per channel
(Add 2.9 watts of ±12VDC for every VA of output per channel)
Therefore, a 1.5 VA Load adds to ±12V 181 mA average, or 288 mA peak per channel
External ±12V input power can be utilized
Ground:
Isolated signal and reference. Channels individually isolated from each other and
from system ground
Weight:
1.5 oz. (42 g)
DLV (Module 5*) – Two/Four Isolated DLV Simulation Ch, LVDT/RVDT Outputs
*See P/N
(Applies to each channel unless noted otherwise)
Number of Channels:
2 (3/4-wire) / 4 (2-wire)
Resolution:
16 bits (.001526% FS)
Linearity:
0.1% FS
Output Gain:
0.1%
Output Format:
Configurable for either 3/4-wire or 2-wire.Galvanically isolated. Output voltage
is programmable fixed or ratio-metric
Output Voltage:
Programmable (See code table and part number)
Output Load:
1.5 VA max @ 11.8 VRMS or 28 VRMS (de-rates linearly as voltage is
decreased) (See code table)
Regulation (VL-L):
5% max. No load to Full load
Excitation Input Voltage:
(See part number), Galvanic isolated. Uses 1 ma max/Channel
Excitation Frequency:
47 Hz to 10 kHz (See part number)
Phase Shift (A/B):
0.5° max. (Between output and reference) (Programmable phase shift)
Settling Time:
Less than 100 microseconds
Module Power:
+5VDC @ 570 mA
±12VDC @ 160 mA (no-load) per channel. (Add 2.9 watts of ±12VDC for every
VA of output per channel). Therefore, a 1.5 VA Load adds to ±12V 181 mA
average, or 288 mA peak per channel
External ±12V input power can be utilized
Ground:
Isolated signal and excitation; Channels individually isolated from each other
and from system ground
