Product features KST RS 485 temperature converters
KST RS 485 - RS 485 temperature converters is intended to convert the signal from resistance type temperature sensing elements Pt 1000/3850 to digital RS 485 / MODBUS RTU signal. These converters can be used in any control system compatible with RS 485 digital output. The converter standard measuring ranges are -50 to 200 ° C. The operating temperature range is -40 ° C to 80 ° C. These limits should not be exceeded even for a short time.
The converters are designed to operate in a chemically non-aggressive environment.
KST RS 485 converter - the plastic housing is made of LEXAN material conforming to the requirements of EN 45545-2 and is identical, for example, to the connection head of KS 120 sensors. It is supplied with a wall bracket or with a clip for fixing on a DIN rail. The plastic housing meets the IP 65 protection requirements according to EN 60 529.
