| Explanation: |
Series ETR - MDR servo signal interface modules; this breakdown covers ETR-20, ETR-36 and ETR-50 only. |
Connector Contacts 20 - 20-contact MDR connector |
ETR modules provide terminal connections for servo drive I/O signals through an MDR connector. Choose the connector contact count to suit the cable assembly and check its signal assignment against the drive. The three models have different footprints and terminal arrangements.
| Model | MDR contacts | Length × width × height | Cable family |
|---|---|---|---|
| ETR-20 | 20 | 66mm × 55mm × 39mm | MDR cable series |
| ETR-36 | 36 | 111mm × 55mm × 39mm | MDR cable series |
| ETR-50 | 50 | 99mm × 55mm × 39mm | MDR cable series |
| Characteristic | All three models |
|---|---|
| Rated voltage | 24VDC |
| Rated current | 1A |
| Dielectric withstand voltage | 2000VAC minimum; test duration not specified |
| Insulation resistance | >5000MΩ at 500VDC |
| Suitable wire size | 26-16AWG |
| Ambient temperature range | -55°C to +105°C |
ETR-50 uses an additional terminal row on the opposite side of the MDR connector. Select by the dimensions of the individual model rather than assuming module length increases with contact count.
