CEV58M-SSI-1-D-1 TR Electronic SSI Encoder

The CEV58M-SSI-1-D-1 operates at a nominal voltage of 24 VDC with a supply range of 11 to 27 VDC.

It draws a typical nominal current of 80 mA under unloaded working conditions.

The unit meets NEC Class 2 requirements for safe power supply in UL and CSA approved systems.

This encoder supports both single-turn and multi-turn counting with a total resolution up to 33 bit.

It provides up to 32768 steps per revolution and can track up to 256000 revolutions accurately.

The output capacity reaches a maximum of 27 bit for precise position feedback.

The CEV58M-SSI-1-D-1 uses an SSI interface with optocoupler clock input and RS‑422 data output.

Its SSI clock frequency ranges from 80 to 1000 kHz with a typical mono time of 20 µs.

An optional incremental interface provides square signals with 1024 or 2048 pulses per revolution.

Incremental outputs use TTL RS‑422 drivers at 5 VDC for stable signal transmission.

The internal cycle time of the CEV58M-SSI-1-D-1 is fixed at 250 µs for fast data updating.

Users can adjust resolution and multiple functions through programmable parameter settings.

It supports TR‑Soft TRWinProg programming tools for easy configuration and setup.

External inputs include count direction control and electronic preset adjustment with defined logic levels.

The device provides 8 short‑circuit proof push‑pull external outputs with up to 50 mA load capacity.

Output levels match the supply voltage and can be programmed according to application requirements.

Mechanically, the encoder reaches a maximum speed of 12000 rpm for high‑speed applications.

Axial shaft load is limited to 50 N and radial load to 100 N to protect internal components.

Bearing life exceeds 3.9×10¹⁰ revolutions under defined speed, temperature and load conditions.

Shaft diameter options include 6 mm, 8 mm, 10 mm, 12 mm and 3/8 inch versions.

Maximum allowable angular acceleration is up to 10⁴ rad/s² for dynamic motion systems.

Moment of inertia is typically 2.5×10⁻⁶ kg·m² with a start‑up torque of 2 Ncm at 20 °C.

Unit weight ranges from 0.3 kg to 0.5 kg depending on mechanical configuration.

The CEV58M-SSI-1-D-1 withstands vibration up to 100 m/s² between 50 and 2000 Hz.

It resists shock up to 1000 m/s² with a half‑sine waveform of 11 ms duration.

The unit complies with DIN EN 61000‑6‑2 for EMC immunity and 61000‑6‑3 for emissions.

Standard operating temperature ranges from 0 °C to +60 °C.

An optional extended range of -20 °C to +70 °C is available for harsh environments.

Storage temperature spans -30 °C to +80 °C in dry non‑condensing conditions.

Relative humidity can reach 98% without condensation to ensure stable performance.

The standard protection class is IP65 against dust and water ingress.

Before installing the CEV58M-SSI-1-D-1, confirm the shaft diameter matches your mechanical design.

Mount the unit using the standard flange position with a 10 mm offset from the shaft load origin.

Ensure axial and radial forces stay within rated limits to extend bearing and service life.

Connect the 24 VDC supply within 11 to 27 VDC to avoid undervoltage or overvoltage damage.

Wire the SSI clock and data lines following RS‑422 standards for reliable long‑distance communication.

Configure desired resolution, counting direction and preset values using TRWinProg software.

Set up incremental output pulses to 1024 or 2048 based on your control system requirements.

Install the encoder in a clean, dry location to maintain IP65 protection and avoid condensation.

Ground the housing properly to improve EMC performance and reduce electrical interference.

After installation, verify position values and output signals to ensure correct operation.
