SDx Module

Introduction

An SDx module can be used with ComPact NSX circuit breakers equipped with MicroLogic trip units.

The SDx module receives data from the trip unit through an optical link:

For MicroLogic 2 trip units, one output (non-configurable) for remote monitoring of the thermal trip alarm
For MicroLogic 4 trip units, two outputs (non-configurable) for remote monitoring of:
- The thermal trip alarm
- The earth-leakage trip alarm
For MicroLogic 5, 6, and 7, two outputs (configurable) for remote monitoring of alarms

NOTE: The SDx module cannot be installed in a ComPact NSX400K circuit breaker.

Installation

The slots used to install the SDx module depend on the circuit breaker type.

ComPact NSX100-250	ComPact NSX400-630

The SDx module cannot be installed at the same time as an MN/MX release and OF contact.

For more information about installation, consult the instruction sheet on the Schneider Electric website: GHD16241AA, ComPact NSX100–630 - SDx Output Module.

Connection

Connect the SDx module and the outputs in strict accordance with the wiring diagram.

MicroLogic 2	MicroLogic 4

MicroLogic 5	MicroLogic 6	MicroLogic 7

The characteristics of the SDx module outputs are:

Voltage: 24–415 Vac/Vdc
Current:
- Active outputs: 80 mA maximum
- Idle outputs: 0.25 mA

Output Assignment Factory Setting

The functions offered by the SDx module outputs depend on the type of trip unit installed with the module

MicroLogic	Output 1 (SD2/OUT1)	Output 2 (SD4/OUT2)
2	Thermal fault indication alarm (SDT)	Not available
4	Thermal fault indication alarm (SDT)	Earth-leakage fault indication alarm (SDV)
5	Thermal fault indication alarm (SDT)	Long-time pre-alarm (PAL Ir). Alarm activated as soon as the current in the load reaches 90% Ir.
6	Thermal fault indication alarm (SDT)	Ground-fault indication alarm (SDG)
7	Thermal fault indication alarm (SDT)	Earth-leakage fault indication alarm (SDV)

NOTE: Outputs SDT, SDG, and SDV return automatically to their initial state when the circuit breaker closes.

Reconfiguring the SDx Module Outputs

Use EcoStruxure Power Commission software to reconfigure the assignment of SDx output 1 (SD2/OUT1) and output 2 (SD4/OUT2), when they are used with MicroLogic 5, 6, and 7 trip units.

For more information about the list of alarms and configuration options using EcoStruxure Power Commission software, refer to DOCA0141EN, ComPact NSXMicroLogic 5/6/7 Electronic Trip Units - User Guide.

The operating mode of the outputs can be configured:

Without latching
With latching (the return to the initial state takes place by acknowledging the latched output using the communication network or the MicroLogic keypad)
Time-delayed without latching (the return to the initial state takes place at the end of the time delay)
Forced to the closed state (the return to the initial state takes place by acknowledging the latched output using the communication network or the MicroLogic keypad)
Forced to the open state (the return to the initial state takes place by acknowledging the latched output using the communication network or the MicroLogic keypad)
