Delay in removing the supply (true off delay on de-energization timer):

• Installing the Electro 11 pin plug-in series of control and timing devices is simple and straightforward since they are designed to fit into a conventional 11 pin base.
• The device offers a delayed relay release upon removal of the supply.
• Internal batteries are included with time ranges of 10 to 180 minutes however, they must be charged for 24 hours prior to use.
• To charge the internal retention circuit, power must be applied for 30% of the time range before being removed.
• Use the pulse-controlled interval timer (T2M or T1I/P) in applications where supply voltage is present.
