RESOLVER
INPUT
S1 and S3, S2 and S4, and RH and RL should be ideally twisted shielded, with the shield tied to GND at the converter.
For DDC-49530: Ri = 70.8 K
, 11.8 V input, synchro or resolver.
For DDC-49590: Ri = 270 K
, 90 Volt input, synchro or resolver.
Maximum additional error is 1 minute.
When using discrete resistors: Resolver L-L voltage = Ri
≥
6 k

S1, S2, S3 should be triple twisted shielded; RH and RL should be twisted shielded;
In both cases the shield should be tied to GND at the converter.
11.8 Volt input = DDC-49530: Ri = 70.8 K
, 11.8 V input, synchro or resolver.
90 Volt input = DDC-49590: Ri = 270 K
, 90 Volt input, synchro or resolver.
Maximum additional error is 1 minute.
When using discrete resistors: Resolver L-L voltage = Rf
≥
