INSTRUMENTATION
New developments in electronics PROMPT PRODUCT updates With the high pace of innovation in electronics, Keller components are regularly assessed and updated to meet the current and increasing demands of its customers.
T
he X-Line digital transmitters have undergone a drastic change in electronics where a completely new electronics series has been developed. Complete with improved specifications and more digital interfaces, the new series is fully compatible with Keller communication protocol and software. For a smooth transition, these adjustments are implemented in phases. The first series was equipped with a new firmware version and an updated Modbus protocol in June 2021. This modification concerns the 23X, 23SX, 26X, 33X, 35X, 36X, 36XW and PD-33X series. The change also applies to custom-made sensors that are equipped with the X-Line electronics (type numbers with an ‘X’ such as the 10LX). The user will not notice any changes to the electronics. There are no changes in usage. The latest updates result in the electronics reacting faster. Furthermore, it can be determined what output signal the sensor will receive. Whether
analogue, digital, RS485, SDI-12 or I2C, Keller can now flexibly choose the signal given to the sensor. The well-known accuracy and competitive price of Keller sensors now have the added advantage that they are equipped with the latest electronics for many different applications.
CANopen This is the communication protocol for bus systems in the automotive industry. CANopen software ensures a universal exchange of data and controls all kinds of basic functions such as an address, to be able to address a participant directly, or a heartbeat, to continuously check whether participants are still present or active. The Series 23SX-C sensors have a CANopen output.
New IO-Link The new Series 21Zio is the first Keller sensor with an IO-Link interface. The compact pressure transmitters of the 21Zio series can be used as both pressure transmitters and pressure switches. Thanks to the universal IO-Link interface, according to IEC 61131-9, the sensor is flexible and can be easily and quickly integrated into intelligent automation and other systems. The switching functions and other parameters can be called up and configured directly via IO-Link. In this way, machine downtimes are kept to a minimum and personnel are relieved.
