Profinet / EtherNet-IP Deterministic Networks and I/O Density Scaling

The MNB1000-15 performs local point expansion through the TAC I/A Series MicroNet BACnet architecture. The module increases controller capacity by adding six Universal Inputs, three Universal Outputs, and six Triac Digital Outputs. A single MNB-1000 controller can support up to eight MNB1000-15 expansion modules, providing a maximum system capacity of 152 I/O points.

The hardware uses removable electronics with screw terminal connections for field wiring access. DIP-switch addressing defines the remote I/O position, while LED indicators provide status information for power, communication, and output activity.

Frequently Asked Questions

Q: What physical signals can the MNB1000-15 Universal Inputs accept?
A: The six Universal Inputs support thermistor signals, RTD inputs, 0-5 VDC analog voltage, 0-20 mA analog current with external shunt resistance, dry contact switching, and pulse input signals.

Q: How are the Triac Digital Outputs electrically configured?
A: The six Triac Digital Outputs provide individually isolated outputs rated at 12 VA at 24 VAC, 50/60 Hz.

Q: What installation interface is provided for field wiring?
A: The module uses fixed and removable screw terminals designed for AWG #14 to #18 wiring connections.

Field Installation Guidelines

Install the MNB1000-15 on a suitable panel or wall-mounted surface according to the MicroNet BACnet controller installation requirements. Verify the 24 VAC power source polarity and wiring separation before energizing the module.

Use dedicated field wiring paths for input signals, analog outputs, and Triac outputs to reduce electrical interference. Shielded cables should be applied where signal noise conditions require additional protection, with cable shields terminated according to site grounding practices.

Confirm DIP-switch addressing before connecting the remote I/O bus. Ensure removable terminal blocks are fully seated and verify LED status indicators after power application.
