Absolute Electro Magnetic Encoder Series TBA / TRA - Analogue Output - Technical Data Sheet

Q: What analogue signal outputs are available for Series TBA / TRA?

Outputs support 0 (4) to 20 mA and 0 to 10 VDC, with ±10 VDC available as an option. Current and voltage outputs can be selected according to the provided electrical output options.

Q: What are the measuring ranges for TBA and TRA encoders?

TBA provides a 360° measuring range (one turn). TRA provides up to 1,474,560° using 4096 revolutions (360° x 4096), with a default-adjustment of 3600° during standard setting.

Q: Which parameters can be changed via Teach-in?

Teach-in allows adjustment of the set zero point, set final value, preset value (middle of the measuring range), code sense (CW or CCW), and the setting of default values.

Absolute electro magnetic encoder Series TBA / TRA with analogue output provides robust position measurement for harsh industrial applications. The design features seawater-proof aluminium or stainless-steel housing, ball bearings for angular recording, and magnetic sensor systems. Using a 12-bit D/A converter, outputs support 0 (4) to 20 mA and 0 to 10 VDC or ±10 VDC. Measuring ranges reach 360° (TBA) and up to 1,474,560° (TRA, 4096 revolutions) with configurable Teach-in parameters, including zero point and final value, and protection up to IP65/IP67.

Absolute electro magnetic encoder Series TBA / TRA Singleturn / Multiturn Analogue output Design - Robust housing (Wall thickness max. 5 mm) manufactured from seawater-proof aluminium (AlMgSi1- 3.2315) or stainless steel (Material: 1.4305 or 1.4404) . - Shaft fitted with ball bearings bears the magnet for recording the angular position and the drive gear of the multiturn transmission for absolute revolution counting - Design form in Ø 42, Ø 50, Ø 58 mm diameter and customer specific applications - Magnetic sensor system(s) for position measurement - Signal output via 12-Bit D/A converter Analogue Signal outputs: 0 (4) to 20 mA, 0 to 10 VDC or ± 10 VDC available. - Electrical connection via connector M12x1 or via cable Data sheet No.: TBA/TRA 14269 FE Date: 09.11.2020 􀂄 Robust design for harsh applications e. g. cranes and construction machinery 􀂄 Magnetic Sensor system(s) 􀂄 Measuring ranges TBA: 360° TRA: 1,474,560° (4096 revolutions x 360°) 􀂄 Protection grade IP 65/ IP67 (IP 69K option) 􀂄 TBA Options - Redundant design (Data sheet 15241) 􀂄 TRA Options: - Redundant design (Data sheet-TRA 12665) - TRA draw wire sensor, see page 11 and 15 Function The rotary encoder has an analogue interface. The D/A converter has a resolution of 12 bits, which are distributed over the maximum measuring range of 360° (TBA) or 360° x 4096 revolutions (TRA) . The sensor TBA has a measuring range of 360 degrees, that means one turn. The encoder TRA provides additionally the revolutions (max. 4096) absolute with a gear. The standard values are 360° at TBA and 1,474,560° (360° x 4096 revolutions) at TRA. The output signal can be parameterised and referenced via Teach-in by means of two multifunction pins (MFP) . For both sensors TBA and TRA the Teach-in functionality is integrated. Via the Teach-in functions following parameters can be changed: Set zero point, set final value, set Preset value (middle of the measuring range), code sense (CW or CCW) and also the setting of the default values. With the functions set zero point and set final value the gradient of the signal output can be changed.
