SYNC 200 series – IED Protocol Upgrade Module

SYNC 200 series – IED Protocol Upgrade Module

With the advent of superior protocols like IEC 61850, there is an increasing need for Intelligent Electronic Devices (IEDs) to be compliant with these new protocols while still maintaining interoperability with legacy ones. Kalkitech’s SYNC 200 series of embedded chip products act as upgrade cards for incorporating latest smart grid substation and metering protocols in existing IED equipment design.

SYNC 200 module series offer the IED manufacturers the ability to upgrade to support almost any protocol like IEC 61850, DNP3.0, IEC 608570-5-101 / 103 / 104 and DLMS/COSEM with minimal change in product design, enabling faster go-to-market, while saving on R&D and product development costs. Additionally, the incremental R&D efforts in keeping up with the latest protocol developments is borne by experienced professionals from Kalkitech rather than the device manufacturers, allowing them to focus on their core strengths.

SYNC 200 series comes in numerous models for varying performance and dimension requirements.

1-SYNC_211 SYNC 211 (OEM S1) One serial and one Ethernet port for low scale protocol conversion; very small form factor. It is an ultra-compact embedded module with an ARM7 based processor, one 10/100 Base T Ethernet network interface, and one TTL serial interface. SYNC 211 enables the future-proofing of legacy devices at an attractive price-point. Dimensions: 36.7 mm x 19.05 mm x 21.69 mm
2-SYNC_221 SYNC 221 (OEM S2) Two serial ports and one Ethernet port for medium/high duty protocol conversion like IEC 61850; small form factor.SYNC 221 is the latest model in Kalkitech’s SYNC 200 series and is designed for the flexibility and performance requirements of small but powerful devices like RTUs and Relays. It has two TTL serial interfaces as well as one 10/100 Base T Ethernet interface. Dimensions: 45mm x 40mm x 21.6mm.
SYNC 200 Series_Model Variants_SYNC 241_V1 SYNC 241 (OEM S4) Four serial ports and one Ethernet port for medium/high duty protocol conversion like IEC 61850; medium form factor. SYNC 241 offers the scalability of 4 TTL interfaces and one 10/100 Base T network interface as well as support for upto 20GPIOs, all in a form factor that is suitable for most applications. Dimensions: 55.4mm x 62.2mm x 24mm
4-241_v3 SYNC 241 CUProvides the same functionality as the SYNC 241 and differs only in size. Dimensions: 55.4mm x 62.2mm x 36mm mm.SYNC 241 FOWill have one fiber optic (FO) interface instead of the one 10/100 Base T network interface. Dimensions: 55.4mm x 62.2mm x 32mm.

Kalkitech has built a Developer Kit that will help test and integrate Kalkitech’s SYNC 200 modules into the vendor end devices quickly and with minimal costs.  The developer kit comes with the necessary developer board and sample embedded modules hardware, configuration tools and documentation.  In addition, up to 20 hours of free Technical Support is available.


SYNC 205 Development board provides a development platform for the SYNC 200 products and projects all the features of a SYNC 200 module for testing and integration. The developer can use the board for customized development of the SYNC 200 products and to explore the possibility of integrating the device into the system. This development platform provides developers with opportunities to implement and test solutions and also to verify the various operations work as intended.

The main features of the development board are:

  • Four serial RS232 ports with full modem on COM 1 and Console port
  • RS485 support
  • On-Board RTC
  • Wide power input range
  • GPIO expansion with LED indication
  • Sockets for various SYNC 200 modules
