• Separate sensor input cabling from high-voltage motor power lines to minimize induced electrical noise.

Frequently Asked Questions

• What internal logic polarity is implemented on the DRT2-ID16-1 input channels?

  The module utilizes a PNP internal I/O common configuration designed for sourcing sensor inputs.

• What voltage threshold defines an active ON state for the inputs?

  An input channel transitions to an active ON state when the signal voltage reaches 15 VDC or higher.

• What are the signal response times for channel switching on this terminal?

  The hardware provides a 1.5 ms ON-delay time and a 1.5 ms OFF-delay time for digital input processing.

• What dual power supply connections are required to operate the module?

  The unit requires 11 to 25 VDC for DeviceNet communications and 20.4 to 26.4 VDC for field I/O circuit supply.

• What degree of environmental ingress protection does the housing provide?

  The physical enclosure carries an IP67 protection rating for harsh industrial environment installations.

• How many input circuits share a single common line on the DRT2-ID16-1?

  All 16 discrete input points are mapped to a single common circuit grouping within the housing.

• What is the maximum allowable OFF-state leakage current per point?

  The input circuitry permits a maximum OFF-state leakage current of 1 mA before triggering an ON state.

• What mounting standard is supported by the physical terminal body?

  The terminal housing features an integrated mounting clip engineered specifically for 35 mm DIN rail mounting.
