Modular device for DIN-EN 60715 TH35 rail mounting.

1 module = 18mm wide, 58mm deep.

State-of-the-art hybrid technology combines advantages of nonwearing electronic control with

high capacity of special relays.

Connection to the Eltako RS485 bus, terminals RSA and RSB.

Up to a total of 128 actuators can be added in this way.

Up to 35 switches are assignable, of which may be one or several central control switches. In

addition, via a wireless antenna module FAM12-12V DC wireless window/door contact (FTK)

with a NO or NC function with the window open. If a direction switch is taught-in, a function

(e.g. TI) can be started using the top switch (START) and stopped with the bottom switch

(STOP).

Patented Eltako Duplex technology (DX) allows you to switch normally potential free contacts

in zero passage switching when 230V A/C voltage 50Hz is switched. This drastically

reduces wear. To achieve this, simply connect the N conductor to the terminal (N) and L to

K(L). This results in an additional standby consumption of only 0.1 watt.

The 12V DC supply voltage of the complete RS485 bus is mainly powered at 6W, 12W or

24W by a switch mode power supply unit SNT12-12V DC that is only 1 or 2 pitch units wide.

When energised, each of the relays of the FMZ12 requires a power consumption of only 0.3 watt.

Time setting between 0.5 second and 20 hours.

Teach-in takes place

using the top and middle rotary switches and then the time is set.

T is the time base and xT the multiplier.

The function is selected

using the bottom rotary switch:

RV

= off delay

AV

= operate delay

TI

= clock generator starting with impulse

TP

= clock gener ator starting with pause

IA

= impulse controlled operate delay (e.g. automatic door opener)

EW

= fleeting NO contact

AW

= fleeting NC contact

ARV

= operate and release delay

ON

= Permanent ON

OFF

= Permanent OFF

The LED

below the upper function rotary switch performs during the teach-in process according

to the operation manual. It shows control commands by short flickering during operation.

* The maximum load can be used starting at a delay time or clock cycle of 5 minutes.

The maximum load will be reduced for shorter times as follows: up to 2 seconds 15%,

up to 2 minutes 30 %, up to 5 minutes 60%.
