[. . . ] Digital Indicators K3HB Series Distinct by Design, Distinguished in Performance K3HB-H K3HB-S K3HB-X K3HB-V Features Red-Green Display Allows Easy Recognition of Judgment Results · The measurement value display can be set to switch between red and green in accordance with the status of comparative outputs. This means that the status can be ascertained at a distance. Short Body with Depth of Only 95 mm (from Behind the Front Panel) · A short body of only 95 mm (see note) contributes to the development of slimmer and smaller control panels and installations. Position Meter Enables Easy Monitoring of Operating Status Trends · The present value with respect to the measurement or display range (full scale) can be viewed on a bar display. The operating status can be grasped intuitively, allowing easy judgement of levels and threshold values. HH H P L LL 27% shorter than earlier models Depth: 95 mm (See note. ) (The depth is 100 mm when mounted to the terminal cover. ) Note: Depth of DeviceNet models is 97 mm. Max Min B L T-ZR CMW Zero Hold TG T HH LL H L Position meter Select a Comparative Output Pattern to Suit the Discrimination or Control Application · The output pattern for comparative outputs can be selected. In addition to high/low comparison with set values, output based on level changes is also possible. [. . . ] DeviceNet models also include a DeviceNet connector (Hirose HR31-5. 08P-5SC(01)) and crimp terminals (Hirose HR31-SC-121) (See note 3. ) Note: 1. DC power supply models require a control power supply capacity of approximately 1 A per Unit when power is turned ON. Particular attention is required when using two or more DC power supply models. For K3HB-series DeviceNet models, use only the DeviceNet Connector included with the product. The crimp terminals provided are for Thin Cables.

Sampling and Comparative Output Response Times The K3HB-S sampling and comparative output response times depend on the calculation methods, timing hold type, and, for simple averaging, the averaging times. Refer to the following description for details. Output Refresh Period The K3HB-S repeats input reads, calculation, and judgement output processing. The output refresh period differs depending on whether there are one or two inputs, as outlined below. Output Response Time The comparative output response time is the sum of the data processing time and the output (relay or transistor) response time.

Power supply input + Digital Indicator Digital Indicator - Surge suppressor 3. In order to prevent inductive noise, wire the lines connected to the terminal block separately from power lines carrying high voltages or currents. Other measures for reducing noise include running lines along separate ducts and using shield lines.
