Example:  81 series, modular timer multi-voltage, 1 CO (SPDT) - 16 A, supply rated at (12…230)V AC/DC. 

**8 1 . 0 . 1 . 0 . 2 3 0 . 0 0 0 0 Series Type** 0 =  Multi-function (AI, DI, SW, SP, BE, DE, EEb) 

**Supply voltage** 230 =  (12 … 230)V AC/DC 

**Supply version** 0 =  AC (50/60 Hz)/DC 

**No. of poles** 1 =  1 CO (SPDT)

Supply Start = Start via contact in supply line (A1). Control signal = Start via contact into control terminal (X-S). 

## **Wiring diagram** 

- Supply START **  Connection of the Reset (R-X) is optional 

- Control signal

- Terminals R, S & X must not be directly connected to the timer supply voltage, but they should be considered to be at supply voltage potential for the purposes of insulation.

## **(AI) On-delay.** 

Apply power to timer. Output contacts transfer after preset time has elapsed. Reset occurs when power is removed. 

## **(DI) Interval.** 

Apply power to timer. Output contacts transfer immediately. After the preset time has elapsed, contacts reset. 

## **(SW) Symmetrical flasher (starting pulse on).** 

Apply power to timer. Output contacts transfer immediately and cycle between ON and OFF for as long as power is applied. The ratio is 1:1 (time on = time off). 

## **(SP) Symmetrical flasher (starting pulse off).** 

Apply power to timer. First transfer of contact occurs after preset time has elapsed. The timer now cycles between OFF and ON as long as power is applied. The ratio is 1:1 (time on = time off). 

## **(BE) Off-delay with control signal.** 

Power is permenently applied to the timer. The output contacts transfer immediately on closure of the Signal Switch (S). Opening the Signal Switch initiates the preset delay, after which time the output contacts reset. 

## **(DE) Interval with control signal on.** 

Power is permenently applied to the timer. 

On momentary or maintained closure of Signal Switch (S), the output contacts transfer, and remain so for the duration of the preset delay, after which they reset. 

## **(EEb) Interval with control signal off.** 

Power is permenently applied to the timer. 

On opening of the Signal Switch (S) the output contacts transfer, and remain so for the duration of the preset delay, after which they reset. 

**H** 

- **  Connection of the Reset (R-X) is optional 

## **RESET function (R)** 

For each and every Example: function and time Supply START; ON delay function range, the timer is **Closing the external reset switch immediately resets the** immediately reset **timer. Opening the reset switch re-initiates the timing** when the reset switch **function.** is closed. Example: Control signal; ON pulse function. **Closing the external reset switch terminates the interval time and resets the timer. To re-start, it is necessary to open the reset switch, before closing the control signal contact.**
