B2J0101 โ Power-on delay
Delayed equipment start after power is applied.
Industrial Delay Relay Modules
This selection page separates ordinary timer and delay modules from safety relays. Use the product links to verify the exact mode, electrical limits and optional housing for the model being ordered.
Delay Relay Module Product Range
B2J0201 โ Trigger delay
External-trigger timing for pumps, conveyors and sequences.
B2J0601 โ Multi-mode delay
One module covering several general timing behaviours.
E4J0101 โ Programmable / cyclic timing
Configurable sequences and repeated cyclic operation.
E4J0102 โ Clock-based timing
Scheduled switching and specialised timing tasks.
E4J-0103 โ Dual-channel linkage delay
Coordinated non-safety machine sequencing.
How to Select a Multi-Function or Cyclic Timer Relay
Start and trigger condition
Decide whether timing starts at power-up, from a digital trigger, from a clock schedule or as part of a repeating cycle.
Output and load
Confirm relay or transistor output, switching voltage, current, isolation and whether the load needs an interposing contactor.
Time range and mounting
Define the minimum and maximum interval, repeat behaviour, supply and whether the order requires a board, enclosure or DIN-rail option.
Safety boundary: none of the timer modules on this page should be used as the safety controller for an emergency stop, safety light curtain or guard-door interlock.
Delay Relay Module Comparison
Write the required ON/OFF sequence and its start condition first. Open the corresponding model page, then confirm the following points against the exact supplied manual; these are ordering checks, not additional features promised for every variant.
| Model | Primary function | Typical selection reason | Confirm before ordering |
|---|---|---|---|
| B2J0101 | Power-on delay | Delayed equipment start after power is applied | Power-up start condition and what happens to the timer after a supply interruption. |
| B2J0201 | Trigger delay | External-trigger timing for pumps, conveyors and sequences | Trigger edge or level, retrigger behaviour and the output state when the trigger disappears. |
| B2J0601 | Multi-mode delay | One module covering several general timing behaviours | The selected mode code, time units and output option in the supplied manual revision. |
| E4J0101 | Programmable / cyclic timing | Configurable sequences and repeated cyclic operation | The ordered control interface, configuration method and behaviour after command or power loss. |
| E4J0102 | Clock-based timing | Scheduled switching and specialised timing tasks | The required clock or voltage-trigger task and whether time retention is needed and documented. |
| E4J-0103 | Dual-channel linkage delay | Coordinated non-safety machine sequencing | The relationship between both channels, their start conditions and retrigger behaviour. |
If the task needs editable logic beyond a fixed timer sequence, compare the E4J0206 non-safety micro PLC against the actual I/O and program requirements. A programmable timer and a micro PLC are not interchangeable solely because both can delay an output.
Frequently Asked Questions
What is a multi-function timer relay?
It is a non-safety control module that provides more than one timing behaviour, such as power-on delay, trigger delay, interval or cyclic operation. Confirm the exact modes on the selected model.
What is a cyclic timer relay used for?
A cyclic timer repeatedly alternates timed on/off states. Typical uses include intermittent pumps, fans, lubrication, indicators and repetitive process sequencing.
Can a delay relay replace a safety relay?
No. A timing module is for ordinary automation and does not provide the monitored dual-channel safety architecture required for emergency stops, guard switches or light curtains.
Are the DIN-rail housing and enclosure standard?
Not across every B2J/E4J order. DIN-rail mounting, bare-board format and enclosure options must be confirmed for the exact ordered configuration.
