HECM INPUT OUTPUT MODULE

19” RACK TYPE MODULAR CONSTRUCTION

HECM Modular Input/Output, having 1U 19” physical structure, provides flexible, smart, functional and reliable solutions for protection and control automation.It could be easily used in the wide area protection systems, thanks to the parallel working feature on a RS485 bus.

COMMUNICATION

The integrated RS485 serial communication port with galvanic isolation protection, supports Modbus RTU protocol and get easily adapted to the SCADA systems. Via optional IEC61850 Protocol Management Card, it can connect to the IEC61850 compatible systems.

INTERNAL EVENT RECORDER

It is an ideal device for wide area protection systems with sequential event recording in 1ms resolution timestamps, enhanced storage(2.000 event buffer) and software supported reporting features. Additionaly by installing optional IRIG-B card, you can time synchronize it with Irig-B format.

LED INDICATION

It has energy saving LED indication, providing high quality illumination. It provides isolated independent LED for each channel status and supervision and ultra bright illumination which could be seen even in the high lighting environments.

FULL SOFTWARE CONFIGURATION

With the help of ISPsim™ software; just one response and release time valid for all channels as well as ModbusID setting can be programmed. Additionally, all I/O channels could be tested in simulator screen and all of time stamped events could be viewed. ISPsim™ software can be downloaded from here

INPUTS AND OUTPUTS

All inputs are isolated with opto-coupler, protected with varistor, having common return terminal and filtered. Fulfill EU Electromagnetic Compatibility (EMC) and Low voltage directive (LVD). False alarm possibility is completely eliminated. The maximum input current is 5mA, the input voltage can be ordered as 24/48V,110/220Vdc upon request.

Outputs could be relay or solidstate type upon switching current requirements. Outputs are voltage supervision type, so that supervision LED corresponding this channel will indicate the situation, in case of any fault or wiring break in the channel.

INPUT AND OUTPUTS ALTERNATIVES

Input card alternatives for each slot ;

• 16 channels input card, 110/220Vdc
• 16 channels input card, 24/48Vdc

Output card alternatives for each slot;

• 8 channels, relay outputs card, breaking rating of [email protected]/ 0,[email protected],
• 8 channels, relay outputs card, breaking rating of [email protected]/ 0,[email protected],
• 4 channels, solidstate outputs card, breaking rating of [email protected]

PROGRAMMABLE RESPONSE AND RELEASE TIME

There are “software programmable” response – release times which provide flexible and safe performance for protection against induced magnetic fields resulted from maneuvers i.e CB opening/closing especially. With the help of ISPsim^TM software; Response and release time valid for all channel are set between 3msec and 250msec. Response time is set to 5msec, release time is set to 20msec by default.
