It is possible to connect the load
between terminals S-A2 (e.g. contactor,
pilot lamp or another device), without
compromising the correct operation of
the relay (the load is energized as long
as the switch button is closed).

• „True OFF“ relay - relay timing without supply voltage.
• Example of use: back-up source for Delay OFF in case of voltage failure
(e.g. emergency lighting, emergency respirator, or protection of el.
controlled doors - in case of fire).
• 2 time functions adjustable by rotary switch:
a - Delayed return after disconnecting of supply.
e - Delayed start.
• Time range (adjustable by rotary switch and fine setting by potentiometer): 0.1 s - 10 min.
• Universal supply voltage AC/DC 12 - 240 V.
• Interruptions in the power supply must take time steps (tens to hundreds of milliseconds).
• Output contact: 2x changeover / DPDT 8 A.
• Output status indicated by red LED (only in case of supply voltage
connection).
• Clamp terminals.
• 1-MODULE, DIN rail mounting.
e - Off Delay (S Break)
