Page 8: Product Overview
KL2784 - Introduction Fig. 1: KL2784 The KL2784 digital output terminal is able to switch voltages up to 24 V AC/DC using advanced MOSFET transistors. The semiconductor switches connected to the power contacts represent a substitute for relay contacts. They are short-circuit proof and free from wear, thereby increasing the availability of the application. -
Page 9: Kl2794 - Introduction
The output is short-circuit-proof to a limited extent. The output transistor can cope with short-term overcurrents until the fuse is triggered. The Bus Terminal has four channels, whose signal state is displayed by LEDs. KL2784 und KL2794 Version: 2.0.0... -

Page 12: Mounting And Wiring
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: 2.0.0 KL2784 und KL2794... -

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. KL2784 und KL2794 Version: 2.0.0... -
Page 14: Fig. 6 Power Contact On Left Side
Power Feed Terminals can be released and pulled at least 10 mm from the group of terminals. Risk of electric shock! The PE power contact must not be used for other potentials! WARNING Version: 2.0.0 KL2784 und KL2794... -
Page 15: Connection
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. KL2784 und KL2794 Version: 2.0.0... -
