Description

LINKNET HT all-in-one machine

8 AI/2 AO, 4-20mA, loop powered

Woodward LINKnet HT distributed I/O nodes are small modules based on CANopen, designed specifically for turbine control in harsh vibration and temperature environments

The LINKnet HT distributed I/O node powered by the Woodward circuit is a small module based on CANopen, designed specifically for turbine control in harsh vibration and temperature environments.

Woodward control systems such as MicroNet Plus can easily program these nodes to collect I/O sensor data from remote locations. Woodward’s GAP graphics application software provides automatic node initialization, RateGroup operation, and diagnostic functions when using these nodes for control:

Gas and Steam Turbines

Gas and diesel engines

Hydraulic turbine

Due to the fact that LINKnet HT nodes can be pried together with turbines or engines, typical installation and maintenance costs for cable, sensor wiring, and on-site troubleshooting can be significantly reduced.

 

Features:

Loop power supply

High temperature operating range from -40 ° C to+100 ° C

High vibration operation with pry mounted vibration and impact levels

18 V to 36 V (DC) isolated input power supply with isolated CAN communication

Benefits:

Suitable for skid mounted turbines and engine control devices

Designed specifically for high-temperature and high vibration operations

Designed for easy integration with Woodward controls such as MicroNet Plus

Provide plug and play integration with Woodward GAP software and RateGroups

Provide a convenient upgrade path for legacy LINKnet distributed I/O nodes

A switch or circuit breaker shall be included in the building installation that is in close proximity to the equipment and within easy reach of the operator. The switch or circuit breaker shall be clearly marked as the disconnecting device for the equipment. The switch orcircuit breaker shall not interrupt the Protective Earth (PE) conductor. Hazardous Locations The Peak200 Digital Control (Front Panel version) shall not be installed in areas exceeding Pollution Degree 2 as defined in IEC 60664-1. Wiring must be in accordance with Zone 2 wiring methods and in accordance with the authority having final jurisdiction. Field wiring must be suitable for the following temperatures: Power Input rated minimum of +95̊C. All remaining connections; +10̊C above highest ambient. Protective Earth Grounding of the Peak200 Digital Control is required to be connected to the PE terminal. The Real Time Clock Battery located on the CPU board is not to be recharged and is not user replaceable. Contact a Woodward Authorized Service Center if a replacement service is needed. The Low Voltage ATEX Peak200 Digital Control is suitable for use in Class I, Div 2, Gas Groups A, B, C and D & European Zone 2, Group IIC environments. For Zone 2 installations, the Peak200 must be installed in an area or enclosure providing adequate protection against high impact (7 Joules). The control is rated for 2 Joules impact. For ATEX/IECEx the Peak200 Digital Control (Front Panel version) shall be installed in an enclosure that is coded Ex nA or Ex e, providing a minimum IP54 ingress protection in accordance with IEC 60079-15. The installer shall ensure that the maximum surrounding air temperature does not exceed the rated temperature of +70 °C at the final installation location. For Zone 2 installations, transient protection for the Peak200 Digital Control is to be provided externally by the end user at the supply terminals of the control. The transient protection device is to be set at a level not exceeding 140% of the peak rated voltage (36Vdc). The risk of electrostatic discharge is reduced by permanent installation of the Peak200 (Bulkhead version), proper connection of the equipment ground lugs, and care when cleaning. This device must not be cleaned or wiped off/against unless the area is known tobe non-hazardous.
