Threshold Value Switch for Railway Applications

WAGO’s new threshold value switch with a coated PCB meets all major standards – from railroad noise (per EN 61373) to temperature influences (per EN 50155) to electromagnetic compatibility (per EN 50121-3-2).

• ▪An even broader portfolio of suitable signal conditioners to choose from
• ▪Reach deeper into the railway industry with standard-compliant products
• ▪Safe 3-way isolation with 4 kV test voltage per EN 61010-1

At a Glance

A wide variety of functions for a huge range of different applications:

• ▪Signal Conditioners
• ▪Frequency Signal Conditioners
• ▪Temperature Signal Conditioners
• ▪Threshold Value Switch
• ▪Potentiometer Signal Conditioner
• ▪Current and Voltage Signal Conditioners and Power Measurement Modules
• ▪3-Phase Power Measurement Modules

Frequency Signal Conditioners

WAGO’s frequency signal conditioners record 0.1 kHz to 120 kHz signals from NAMUR, NPN or PNP sensors and convert the frequency into an analog standard signal.

• ▪Signal acquisition from NAMUR, NPN or PNP sensors
• ▪Frequency range: 0.1 … 120 kHz
• ▪Fault signaling: Wire break/short-circuit detection for NAMUR proximity sensors
• ▪Signaling measurement range underflow/overflow

Temperature Signal Conditioners

With WAGO’s temperature signal conditioners, signals from Pt, TC, Ni, KTY and RTD sensors and resistors can be recorded and converted into an analog standard signal on the output side. Whether a resistive temperature device or a thermocouple is used depends on factors such as the maximum temperature range, the installation environment and the required measurement accuracy:

• ▪Resistive temperature device (RTD): Temperature range up to 850 °C, high accuracy
• ▪Thermocouple (TC): Temperature range up to 2320 °C, better response time

• ▪Signal acquisition from Pt, TC, Ni, KTY and RTD sensors and resistors up to 4.5 kΩ (e.g., Pt100 sensors)
• ▪2-, 3- and 4-wire connection technology
• ▪Fault signaling: wire break/short-circuit detection of the sensor
• ▪Signaling measurement range underflow/overflow

Threshold Value Switch

WAGO’s threshold value switches monitor various measurement signals such as temperature, current or voltage. If a value falls above or below a limiting value setting, emergency stops or alarms can be triggered, for example. In addition to threshold value switches for analog signals, WAGO also offers RTD threshold value switches for resistance temperature sensors and potentiometers, as well as TC threshold value switches for thermocouples, allowing both signal monitoring and measurement.

• ▪Input/output response simulation (2857 Series)
• ▪Relays as threshold value switches (e.g., activation/deactivation delay)
• ▪A digital signal output (DO) reacts to freely configurable measurement range limits (this allows use as a threshold value switch – with activation/deactivation delay).

Potentiometer Signal Conditioner

This potentiometer signal conditioner records resistance signals; e.g., from potentiometers, and converts them into a standard analog signal.

• ▪Signal acquisition from potentiometers and resistors
• ▪Automatic potentiometer identification
• ▪Configurable input and output parameters
• ▪A digital signal output (DO) reacts to freely configurable measurement range limits (this allows use as a threshold value switch – with activation/deactivation delay).

Current and Voltage Signal Conditioners and Power Measurement Modules

Besides current and voltage signal conditioners which record DC and AC currents and voltages, this impressive range also includes a power measurement module that can measure current and voltage in parallel, convert them to power and output them as an analog standard signal. Additionally, WAGO’s signal conditioner for Rogowski coils offers a solution for retrofitting existing systems. Thus it is not necessary to disconnect the live conductor. The new WAGO 3-Phase Power Measurement Module measures all relevant parameters in a three-phase supply network – voltage, current, power, harmonics, etc. – from within the control cabinet.

• ▪Signal acquisition of DC and AC voltages up to 300 VAC/VDC using modules that are just 6 mm wide
• ▪AC currents up to 4000 A via Rogowski coil
• ▪Switchable filter function to prevent signal interference
• ▪A digital signal output (DO) reacts to freely configurable measurement range limits (this allows use as a threshold value switch – with activation/deactivation delay).

3-Phase Power Measurement Modules

The power measurement modules in a DIN-rail mounting enclosure offer the ideal solution for measuring currents and voltages in a three-phase supply network remotely from the control level. Measured variables such as active/apparent/reactive power, energy consumption, power factor, phase angle and frequency can be accessed via Modbus® interface. Two integrated RJ45 sockets streamline the interconnection of up to 32 devices.

• ▪Measurement via current transformers or Rogowski coils: Flexible selection of upcoming measurement tasks
• ▪Slot for microSD cards: Fast and secure mobile measurement, including recording
• ▪Compact device in DIN-rail-mount enclosure: Saves space in building technology
• ▪Modbus® Interface (RS-485): Provision of the measured values via Modbus®
• ▪Digital signal output as pulse output (pulses/kWh are configurable): Continuous energy consumption monitoring

Interface Configurator

The signal conditioners are all user-friendly and easy to configure with the interface configurator.

• ▪Simulation of input and output parameters (2857 Series)
• ▪Automatic module detection
• ▪Configuration and visualization of process values
• ▪Parameterization of the digital switch output (threshold functionality)
• ▪Communication via WAGO USB Service Cable (750-923) or WAGO Bluetooth® Adapter (750-921), pluggable on both series

Configuration Display

The Removable Display can be quickly and easily attached to the housing. It includes an innovative touch panel for intuitively configuring devices. The multicolor display changes between orange, red, green and white depending on the device’s current status. Integrated capabilities, such as the copy function, can transmit stored configuration data from one device to another of the same type. Passwords for protecting configured data can be assigned to prevent unauthorized access and changes.

• ▪Can be easily plugged into signal conditioners
• ▪Touch functionality via control environment
• ▪Automatic module detection
• ▪Configuration and visualization of process values
• ▪Copy function for copying configuration data from device to device
