Page 4: Introduction
Section 1 – Introduction Introduction The electronic switches of the TOE 9261 series are used for time-specific switching on and off of load and signal currents. These devices use an electronic, unidirectional power switch as well as four electronic bidirectional signal line switches. The power switch can be used either to switch a positive supply line or to switch the return line, e.g. -
Page 5: Overview Of Features
- Protected against overcurrent / short-circuit, excessive temperature, excessive switching frequency Model overview Series TOE 9261 devices are available in models for various rated currents. The rated current of the power switch is indicated by a hyphenated number added to the basic part number. -
Page 6: Operation
( 2.6.4 Excessive temperature protection). Series TOE 9261 devices are designed so that they can be used either as tabletop units or in 19" rack systems. Appropriate adapters for 19" rack use are available as an option. -
Page 7: Description Of The Controls
Description of the controls At the end of the manual you will find the various operating and display elements for the series TOE 9261 numbered with front panel and rear views. In the following the individual operating elements are explained in detail. - Page 8 Terminal block for signal line switches S3 and S4. These can be used with suitable [14] terminal block plugs ( 4.1 Technical data TOE 9261, Connections, Signal line switches). The control and signal lines to be switched are routed through the signal line switches indicated by the switch symbols S3 and S4.

Page 10: Connection Of The Consumer For Switching The Positive Supply Line
In the described switch configuration, the negative return line must always be connected from the consumer to the voltage source via the minus sockets of the TOE 9261. These minus sockets must never be bypassed, because otherwise some protection mechanisms of the Electronic Switch are without effect, and damage to the Electronic Switch may result. -

Page 12: High-Impedance Base Load
The current which is drawn by the consumer during the turn-on phase of the PWM is allowed to have values up to the rated current of the TOE 9261. If the current draw is higher, the overcurrent protection on the TOE 9261 may be triggered during the turn-on phase of the PWM. -

Page 14: Protection
Feedback from the (buffered) load side to the OUT output of the power switch must have the indicated polarity and not exceed the rated voltage of the TOE 9261, i.e. the voltage connected to OUT must not be more positive than the voltage at the Plus sockets or more... -
Page 15: Excessive Temperature Protection
If the component temperatures continue to rise, the internal driver stages are shut off, i.e. the switching paths are no longer driven. This fault condition is indicated by the OVL LED. After an appropriate cool-down time the unit can be reset by turning it off and on using the mains switch. TOELLNER Electronic Instrumente GmbH... -
