HD Bus Terminal, 16-channel digital output 24 V , 0.5 A, with diagnostics The KL2819 Bus Terminal has 16 digital output channels for the switching of 24 V loads up to 0.5 A. The integrated diagnostics can be evaluated by the controller and indicated by the LEDs. Overtemperature and the lack of a voltage supply to the terminal are supplied as diagnostic information.

These are limited by an integrated freewheeling diode to approx. -35 V. Since the current reduces only slowly, a delayed switch-off can occur in many control applications. For example, a valve remains open for many milliseconds. Switch-off times are realized that correspond, for instance, to the switch-on time of the coil. KL2819 Version: 1.1.0...
This can be achieved, for example, through adherence to load-specific standards. ◦ Option 1: Ground feedback and all-pole disconnection The ground connection of the connected load must be fed back to the safely switched ground. Version: 1.1.0 KL2819...
If solution option 1 is not feasible, the ground feedback and all-pole disconnection can be dispensed with if the danger of feedback due to a cable short-circuit can be excluded by other measures. These measures, which can be implemented alternatively, are described in the following sections. KL2819 Version: 1.1.0...
• Surroundings (working place, packaging and personnel) should by grounded probably, when handling with the devices. • Each assembly must be terminated at the right hand end with a KL9010 bus end terminal, to ensure the protection class and ESD protection.

To mount the mounting rails with a height of 7.5 mm under the terminals and couplers, you should use flat mounting connections (e.g. countersunk screws or blind rivets). Version: 1.1.0 KL2819...
EL91xx, EL92xx) interrupt the power contacts and thus represent the start of a new supply rail. PE power contact The power contact labeled PE can be used as a protective earth. For safety reasons this contact mates first when plugging together, and can ground short-circuit currents of up to 125 A. KL2819 Version: 1.1.0...
Power Feed Terminals can be released and pulled at least 10 mm from the group of terminals. WARNING Risk of electric shock! The PE power contact must not be used for other potentials! Version: 1.1.0 KL2819...
Insert the new component and plug in the connector with the wiring. This reduces the installation time and eliminates the risk of wires being mixed up. The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3 mm. The maximum height of the terminal remains unchanged. KL2819 Version: 1.1.0...
Ultrasonically “bonded” (ultrasonically welded) conductors Ultrasonically “bonded” conductors It is also possible to connect the Standard and High Density Terminals with ultrasonically “bonded” (ultrasonically welded) conductors. In this case, please note the tables concerning the wire-size width [} 23]! Version: 1.1.0 KL2819...
The cables are released, as usual, using the contact release with the aid of a screwdriver. See the following table for the suitable wire size width. KL2819 Version: 1.1.0...
EL/KL terminals to face forward (see Fig. Recommended distances for standard installation position). The terminals are ventilated from below, which enables optimum cooling of the electronics through convection. “From below” is relative to the acceleration of gravity. Version: 1.1.0 KL2819...
Other installation positions All other installation positions are characterized by different spatial arrangement of the mounting rail - see Fig Other installation positions. The minimum distances to ambient specified above also apply to these installation positions. KL2819 Version: 1.1.0...

All registers can be read or written via register communication [} 35]. They are used for the parameterization of the terminal. R8: Terminal description Register R8 contains the designation of the KL2819 terminal: 0x0B03 (2819 R9: Firmware version Register R9 contains the ASCII coding of the terminal's firmware version, e.g. 0x3141 (1A) .
