Alternative / Replacement for 1770-KF2, 1784-P(KTX), 1784-PCMK or SST 5136-SD

The DataLink GW1000-DHP1 is a low cost, compact alternative to Allen-Bradley’s 1770-KF2. Also provides the same functionality as the 1784-P(KTX), 1784-PCMK or SST 5136-SD.The DataLink converts A-B DF1, (Modbus & ASCII also available) serial protocol to A-B DH+ network protocol providing a serial interface to DH+ for computers, modems and OEM equipment. Applications include PLC programming and graphical user interfaces (GUIs and MMIs) such as RSLINX, RSLOGIX, Wonderware, Kepare, Intellution, Citect, etc. The serial DF1 to DH+ conversion protocol available in the GW1000-DHP1 is the same one available in the GW1000 product. The GW1000”s size, portability, and the choice between a freestanding and DIN rail model make it especially convenient for use in the office, the plant floor, or when travelling.
