Function and features

The multifunction relay T 700 is a time-controlled switching amplifier for pnp-switching sensors and speed monitors, but it can also be triggered by mechanical contacts or push Buttons.

The switching of the output relay depending on the input signal can be influenced via timers with different functions.

Functions

The output relay switches:

ON delay
OFF delay
ON and OFF delay
ON pulse
OFF pulse
- delayed ON pulse
- delayed OFF pulse

The functions ON delay and OFF delay are active all the time. If one function is not needed it must be set to the lowest value (approx. 250 ms).

Please note

If the T 700 in function "OFF pulse" is connected to the operating voltage this causes a fleeting pulse of the output relay.

Operating elements and indicators

1 Selector switch for the time ranges with ON delay (AV)

2 Selector switch for the time ranges with OFF delay (RV) and fleeting pulse

3 Pot for the fine setting of the ON delay time

4 Pot for the fine setting of the OFF delay time and the fleeting pulse

5 Selector switch for: ON delay and/or OFF delay ON pulse OFF pulse

6 LEDs for: Netz Signal Switching state green

Time ranges

There is one time range available for the ON delay and one for the OFF delay. The entire time ranges of 0.25 to 640 seconds are divided into four individual ranges which can be set with a switch.

Position Time range switch (t1/t2) [seconds]
I 0,25...2,50
II 1...10
III 8...80
IV 64...640

Setting of the time

After preselection of the time range the time is set with the corresponding pot. This scale is divided by percentage of the time range end value (10...100%).

Pot (t1/t2) Time [%] [approx.	seconds]
	I	III	IV
10	0.25	1	8	64
20	0.50	2	16	128
30	0.75	3	24	192
40	1.00	4	32	256
50	1.25	5	40	320
60	1.50	6	48	384
