Consumption AC supply DC supply Built-in battery for time function Nominal voltage Capacity Charging current Discharging current 5V 40 mAh 360 A 120 A When power supply is interrupted, the time period starts and at expiration of the set time period, the relay releases. If power supply is reapplied before the relay is released, the time is reset and the relay remains on. The built-in battery is recharged when power supply is applied and is discharged during the time periods. To maintain sufficient energy in the battery, the relay must be recharged for at least one third of the total discharging periods as the recharge/discharge current ratio is 3:1. The capacity of the built-in battery is sufficient for more than 300 h of continuous time measuring without recharging it. LED, red Time Setting Time setting Knob-adjustable on scale in seconds, minutes or hours. Mode of Operation The relay operates immediately after power supply is applied. 200 ms Wiring Diagram Please note The SB 135 should not be operated by short pulses. For this purpose the relay DMB01, operated by means of an external contact function, should be used. NB! It is recommended to connect the SB 135 to the power supply for 48 hrs before it is put into regular service in order to compensate for energy losses due to e.g. a long storage period. Battery control PE = pin 7 Power supply Battery Control Between pins 6 and 7. Pin 6 positive. Rj = 1 k. Curve I Ideal battery voltage at uninterrupted power supply. Curve III Course of battery voltage. The recharging periods must always equal at least one third of the total discharging periods. Curve II Min. battery voltage. Battery should be recharged before voltage drops to min. level. 2 Specifications are subject to change without notice (14.03.01) SB 135 Operation Diagram Power supply Relay on Charging of battery Discharging of battery Specifications are subject to change without notice (14.03.01) 3
