Circle count: 2 bit multi-circle counter (up to 4 circles)

Sampling period: Programmable from 500 μs to 32.767 s

Input signal: Resolver (Resolver) sine / cosine analog signal

External synchronization: With external strobe input (Strobe Input), can be synchronized with external events

Operating voltage: 5 V DC (power supply from the backplane)

Power consumption: Approximately 2.5 W

Size (approx.): 170 × 170 × 40 mm

Weight (approx.): 1.4 kg

Installation: Standard AutoMax backplane slot installation

III. Interfaces and Communications

Resolver interface: 1 resolver input, differential sine / cosine

Backplane communication: Compatible with Reliance AutoMax PLC bus

Status indication: LED power / fault indicator lights

External synchronization: 1 external Strobe input (TTL level)

IV. Core Functions

Resolver position decoding: Converts resolver analog signal to digital position value

High-precision position feedback: Used for closed-loop control of servo motors / spindle angles and speeds

Multi-circle position tracking: 2-bit counter, supports absolute position memory within 4 circles

High-speed sampling: Updates position data at least once every 500 μs

System synchronization: Synchronous sampling triggered by external Strobe signal

V. Application Scenarios

Servo position feedback for Reliance AutoMax PLC system

High-precision angle control for machine tools, rolling mills, textile machinery, etc.
