DANGER
Hazardous voltage.
Will cause death or serious injury.
Disconnect power before working
on equipment.
Reliable functioning of the equipment is only ensured with certified components.
The devices must be installed in a switchgear cabinet with the IP32, IP43 or
IP54 degree of protection, depending on the ambient conditions.
IMPORTANT NOTICE
The products described herein are designed to be components of a custom-ized
machinery safety-oriented control system. A complete safety-oriented system
may include safety sensors, evaluators, actuators and signaling components. It
is the responsibility of each company to conduct its own evaluation of the effec-
tiveness of the safety system with the help of suit-ably trained persons. Sie-
mens AG and its subsidiaries and affiliates (collectively "Siemens") are not in a
position to evaluate all of the characteristics of a given machine or product or
machine not designed by Siemens.
Siemens accepts no liability for any recommendation that may be implied or sta-
ted herein. The warranty contained in the contract of sale by Siemens is the sole
warranty of Siemens. Any statements contained herein do not create new war-
ranties or modify existing ones.
Application
The 3TK2830 is used to expand the enabling circuits. You can combine it with
any 3TK28 basic unit. The maximum achievable safety category according to
DIN EN 954-1 is the category of the basic unit, providing the external circuit
(connection between the basic unit and the expansion unit) is fail-safe.
Functions and connections
The 3TK2830 has four safe enabling circuits as NO circuits and one positively-
driven NC circuit. Two LEDs indicate the operating condition.
The 3TK2830 can be controlled via any enabling circuit in the basic unit. NC cir-
cuit 51/52 of the 3TK2830 is looped into the feedback circuit of the basic unit.
The internal circuit is functionally tested by the upstream basic unit.
