DOLD UG 6960 Multifunctional Safety Timer Review: Specs, Price and Applications
UG 6960 combines a defined safety input function with selectable delay behavior and both instantaneous and delayed safety contacts. DOLD offers application variants for functions such as emergency stop, safety gates, light curtains and two-hand control. These variants are not one interchangeable universal input circuit: the full ordering code determines the function, monitoring and timing range.
Quick Verdict
Consider UG 6960 for a compact, hardware-configured safety sequence where the required delay is established by the machine design. Its rotary selection avoids a programmable-controller project, but time-function selection, wiring and validation remain engineering tasks. A timer does not measure actual standstill.

Design and Engineering Assessment
A release delay can keep a guard permission withheld while motion decays, but its set time must cover the actual worst-case stopping behavior. Temperature, payload, worn brakes and interrupted power can change that behavior. If the application requires verified standstill rather than elapsed time, a timer alone does not provide that measurement.
Instantaneous and delayed contacts perform different jobs. Map each output into the intended stopping and release sequence, including the de-energized state. The semiconductor monitoring outputs are diagnostic signals; do not silently substitute them for the documented safety-contact path.
The manufacturer lists several maximum time ranges, including long-duration versions. Those family options are not settings available on every delivered unit. For example, a 300-second ordering configuration must not be described as a 300-minute unit merely because both appear in the selector.
Select Function Before Wiring
Specify the safety-input variant, cross-fault monitoring, supply, terminal style, delay function and range together. Use the particular wiring diagram and permitted contact load; thermal-current figures do not establish switching capability for every inductive load.
Set and protect the adjustment as required by the instructions. Record the accepted switch positions, timing value and hardware identity with the machine documentation.
Validate Delay and Recovery
Measure the implemented sequence against actual stopping time and the defined acceptance margin. Test power interruption, manual or automatic start behavior and relevant faults through the approved safety-validation procedure.
Verify that restoring the timer, closing a guard or resetting the circuit does not unexpectedly restart the process. A successful timed production cycle alone is insufficient evidence of a protective function.
Applications and Selection
Timed industrial safety sequences with a defined input circuit and validated stopping or access-release requirement.
For DOLD UG 6960 Multifunctional Safety Timer, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Request a quote for the exact ordering code, supply, contact arrangement, accessories and integration scope. Confirm the applicable instructions and documentation with the delivered configuration.
Compare complete installed alternatives using the same required protective function, diagnostic coverage, service procedure and acceptance criteria. Hardware cost alone does not represent the engineering and validation effort.
Pros and Cons
Advantages
Instantaneous and delayed safety contacts in 22.5 mm
Hardware-selectable delay functions
Application variants for several defined safety inputs
Limitations
Not a standstill sensor
Input and timing scope vary by order code
Contact loading and restart behavior require validation
Who Should Consider DOLD UG 6960 Multifunctional Safety Timer?
Consider this configuration when timed industrial safety sequences with a defined input circuit and validated stopping or access-release requirement matches a documented project requirement. Preserve the complete selected identity, interfaces and accepted operating procedure for commissioning and maintenance.
DOLD UG 6960 Multifunctional Safety Timer FAQ
Is UG 6960 a standstill monitor?
No. It implements a configured time function; it does not directly measure whether the mechanism has stopped.
How many safety contacts are described?
Two instantaneous normally open contacts and two delayed normally open contacts.
Are monitoring outputs equivalent to safety contacts?
No. Use them only for the diagnostic role permitted by the selected instructions.
Does every unit have a 300-minute range?
No. The delivered time range follows the exact ordering code.
Can one input variant cover every sensor?
No. Match the specified E-stop, gate, light-curtain, two-hand or other application circuit.
Does component PL e certify the machine?
No. The complete safety function needs calculation, implementation and validation.
How should delay be chosen?
From the actual hazard and worst-case stopping behavior, with the required design margin and approved validation.
What settings should maintenance retain?
Ordering code, time range, selected function/value, wiring, start mode and accepted test records.
Prices are indicative and may change. Confirm the final configuration, commercial terms and delivery schedule before ordering.
