Zeitrelais / Time-Relais – in-case – Multifunktionsrelais / Multi-function timing relay – ITM17
On delay and off delay with external control input (ERs):
NORMAL: The power supply (U) must be present to control the time
function with the external control input (B1). By closing the external
control contact (B1) the on delay time (t1) starts.
the on delay time (t1) the output relay (R1) pulls in.
external control contact (B1) the off delay time (t2) starts.
tion of the off delay time (t2) the output relay (R1) drops out.
SPECIAL TIMING: If the external control contact (B1) is present for a
shorter time than the on delay time (t1) the output relay (R1) remains
dropped out. If the external control contact (B1) is not present for a
shorter time than the off delay time (t1) the output relay (R1) remains
pulled in.
POWER OFF: Independent of the state of the external control input
(B1) the output relay (R1) drops out if the supply voltage (U) is re-
moved.
On delay and on pulse / delayed single shot (EW):
NORMAL: By turning on the power supply (U) the time function
starts.
After expiration of the on delay time (t1) the output relay (R1)
pulls in and the on time (t2) starts.
After expiration of the on time (t2)
the output relay (R1) drops out.
The output relay (R1) remains
dropped out until the supply voltage (U) is removed.
SPECIAL TIMING: If the power supply (U) is present for a shorter
time than the on delay time (t1) the output relay (R1) remains
dropped out.
POWER OFF: The output relay (R1) always drops out if the supply
voltage (U) is removed.
On delay and on pulse / delayed single shot with external control
input (EWs):
NORMAL: The power supply (U) must be present to control the time
function with the external control input (B1). By closing the external
control contact (B1) the on delay time (t1) starts.
the on delay time (t1) the output relay (R1) pulls in and the on time
(t2) starts.
After expiration of the on time (t2) the output relay (R1)
drops out.
The output relay (R1) remains dropped out until the exter-
nal control contact (B1) is opened and closed again.
On delay and on pulse / delayed single shot with external control

SPECIAL TIMING: If the external control contact (B1) is present for a
shorter time than the on delay time (t1) the output relay (R1) remains
dropped out.

SPECIAL TIMING: If the power supply (U) is present for a shorter
time than the on time (t1) the output relay (R1) drops out if the power
supply (U) is removed.
POWER OFF: The output relay (R1) always drops out if the supply
voltage (U) is removed.
On pulse single shot with external control input (Ws):
NORMAL: The power supply (U) must be present to control the time
function with the external control input (B1). By closing the external
control contact (B1) the output relay (R1) is pulled in and the time
function starts. After expiration of the on time (t1) the output relay
(R1) drops out.
external control contact (B1) is opened and closed again.
SPECIAL TIMING: If the time between two closings of the external
control input (B1) is shorter than the on time (t1) the output relay (R1)
remains pulled in.
POWER OFF: Independent of the state of the external control input
(B1) the output relay (R1) drops out if the supply voltage (U) is re-
moved.

On pulse and off pulse with external control input (WOs):
NORMAL: The power supply (U) must be present to control the time
function with the external control input (B1). By closing the external
control contact (B1) the output relay (R1) is pulled in and the first time
function starts. After expiration of the on time (t1) the output relay
(R1) drops out. By opening the external control contact (B1) the
output relay (R1) is pulled in and the second time function starts. After
expiration of the on time (t2) the output relay (R1) drops out.
SPECIAL TIMING: If the time between two closings of the external
control input (B1) is shorter than the first on time (t1) the output relay
(R1) remains pulled in. If the time between two openings of the
external control input (B1) is shorter than the second on time (t2) the
output relay (R1) remains also pulled in.
POWER OFF: Independent of the state of the external control input
(B1) the output relay (R1) drops out if the supply voltage (U) is re-
moved.
Off pulse with external control input (Os):
NORMAL: The power supply (U) must be present to control the time
function with the external control input (B1). By opening the external
control contact (B1) the output relay (R1) is pulled in and the time
function starts. After expiration of the on time (t1) the output relay
(R1) drops out.
The output relay (R1) remains dropped out until the
external control contact (B1) is closed and opened again.
SPECIAL TIMING: If the time between two openings of the external
control input (B1) is shorter than the on time (t1) the output relay (R1)
remains pulled in.
POWER OFF: Independent of the state of the external control input
(B1) the output relay (R1) drops out if the supply voltage (U) is re-
moved.
