Specifications

The series 8000 Single-Turn and Multi-turn (dual) Resolver
Decoder Input Modules use state-of-the-art CMOS circuits to
provide high-noise-immunity and low-backplane-current
requirement. These modules are used to decode resolver signals
and provide decoded digital position information to an Allen-
Bradley PLC*.
Single and Multi-Turn
The single-turn module decodes resolver signals into 3 or
4-digit BCD rotary position and the multi-turn module pro-
vides 6-digit BCD linear position. All models feature digital
static-offset thumbwheels to facilitate aligning resolver zero
during machine set-up. In addition, these modules have a
bright-LED display, a built-in BCD remote display driver bus
for each digit (compatible with AVG Automation 1855D
remote display).
Allen-Bradley-Compatible
The Resolver Decoder Input Modules are fully Allen-Bradley-
compatible and plug directly into any A-B 1771 I/O rack. The
single-turn modules use single-turn resolvers such as the AVG
Automation RL100, RL101, E7R, or E8R.
The multi-turn modules use multi-turn (dual) resolvers such
as the AVG Automation SAC-RL210. The single-turn 3 and
4-digit input modules occupy two I/O slots (1 word) and
the multi-turn 6-digit input modules occupy three I/O slots
(1
1
/
2
words).
Fully Absolute Rugged Encoder
Series 8000 resolver decoder, in conjunction with AVG
Automation's resolvers, provides a fully absolute encoder.
Even if a machine moves during power outage the resolver
always knows its true position when the power is restored.
The NEMA 13 resolver can withstand hostile environment
such as mechanical shock, vibration, extreme humidity &
temperature changes, oil mists, coolants, solvents, and can be
mounted 2,500 ft (762 m) away from the decoder. The ratio-
metric converter assures high tracking speed of 1,800 RPM
and very-high noise-immunity.
Variety of Models
A variety of resolver decoder input models are available to
meet the requirements of different application needs.
