Timers Two-state Delay on Operate Type S 1151 * 4 selectable time ranges: 0.15 s to 800 s * Automatic start * Separate time-setting for the two delay on operate time periods * Repeatibility deviation: 1% * Selection of order of relays * Output: 2 x 10 A SPDT relay * Plug-in type module * S-housing * LED-indication for relay 1 and relay 2 on * AC or DC power supply Product Description Ordering Key Two-state delay on operate, plug-in time relays. Often used in applications with pumps where a delay is necessary at start and restart, Housing Type/Function Output Power supply and if the capacity of the first pump is insufficient no. 2 starts after a given delay. This may be done automatically by means of the SG 125.

Selection of function DIP-switch selector 1 At the end of the set time period, relay 1 operates and the time period for relay 2 starts. At the end of the second set time period, relay 2 operates and both relays will not release until power supply is interrupted. Installation cat. III (IEC 60664) The order of the relays can be inverted by means of a DIPswitch at the front of the housing or by interconnecting pins 5 and 7 on the socket. If power supply is interrupted for at least 200 ms, the time relay and time circuit are reset and the relay is ready for a new time period. 1 2 3 4 5 Relay 1 operates first (pins 1,3 and 4), when the DIP-switch at the front of the housing is in OFF-position 1 2 3 4 5 Relay 2 operates first (pins 8,9 and 10) when the DIP-switch at the front of the housing is in ON-position Reverse function (pins 5 and 7) Wiring Diagram Ext. reversion 200 ms 200 ms LED, red LED, red IP 20 B 2 (IEC 60664) -20 to +50C (-4 to +122F) -50 to +85C (-58 to +185F) 200 g 125 g UL, CSA Selection of time-range T1: DIP-switch selector (2&3) T2: DIP-switch selector (4&5) 1 2 3 4 5 0.15 - 3 s 0.6 - 12 s 5 - 100 s 40 - 800 s Time setting Knob-adjustable on scale in per cent of max. time.
