Off-Delay Timer Relays
An off-delay timer relay is a timer relay that keeps its output contact energized for a set time after the control signal or supply is removed, and releases it when the time expires. It is used in applications where the load must stay in circuit for a while after the command ends, such as running a cooling fan a little longer after a motor stops or turning off lighting with a delay. The category includes Entes DG-10 and DG-60 and Tense ERV-DG models; product data lists time ranges adjustable up to 10 minutes and 60 minutes, with 220 V AC and 230 V AC supply. Select the relay by time range, supply voltage, whether the delay starts when the supply is removed or when a separate control input is released, number of contacts and their current, and housing type. An off-delay relay is not an on-delay timer relay, which pulls in after a delay once energized; the two cannot be used in place of each other in the same circuit.

How to choose Off-Delay Timer Relays
An off-delay timer relay is a timer relay that keeps its output contact energized for a set time after the control signal or supply is removed, and releases it when the time expires. It is used in applications where the load must stay in circuit for a while after the command ends, such as running a cooling fan a little longer after a motor stops or turning off lighting with a delay.
- Separate sensing, motion control, logic processing and operator interface requirements.
- Select signal type, supply voltage, communication protocol and I/O count for the machine network.
- Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
Frequently asked questions
What is Off-Delay Timer Relays and where is it used?
An off-delay timer relay is a timer relay that keeps its output contact energized for a set time after the control signal or supply is removed, and releases it when the time expires. It is used in applications where the load must stay in circuit for a while after the command ends, such as running a cooling fan a little longer after a motor stops or turning off lighting with a delay.
What should I compare when choosing Off-Delay Timer Relays?
Select the relay by time range, supply voltage, whether the delay starts when the supply is removed or when a separate control input is released, number of contacts and their current, and housing type.
Where can I find technical details for Off-Delay Timer Relays products?
An off-delay relay is not an on-delay timer relay, which pulls in after a delay once energized; the two cannot be used in place of each other in the same circuit.
