9.14 K50, Sensor Module Cabinet-Mounted SMC30
X521/X531 encoder connection 2 for HTL/TTL/SSI encoder with open-circuit monitoring
Table 9- 29
Connector
Max. connectable cross-section: 1.5 mm²
Note
Operation of unipolar HTL encoders
When unipolar HTL encoders are used, terminal block A*, B*, and R* must be jumpered with
M encoder (-X531).

Connector
Max. connectable cross-section: 1.5 mm²
Measuring current via temperature sensor connection: 2 mA
Accuracy of the temperature measurement:
1)
- KTY: ±7 °C (including evaluation)
- PT1000: ±5 °C (PT1000 tolerance class B according to EN 60751 including evaluation)
- PTC: ±5 °C (including evaluation)
