Sensor with 230V input

The SIENNA SM1L sensor has one 230V input. The input can be connected to a light switch or other switching elements (e.g. motion detector, thermostat etc.). For optimized wiring, L, N can be extended via the additional L, N terminals.

One binary input (L, 1) with 230V / ~50Hz. Can also be used with switches that have an integrated control light.

Sensor with 2 digital inputs

The SIENNA SM2 sensor has two digital inputs (internal 5V) which can be connected to one 2-gang switch or to two separate switches.

This sensor controls 2 actuators with addresses (g, e) und (g, e +1).

Low voltage inputs: potental-free switching elements required!

Two digital (internal 5V) inputs for connecting to a 2-gang switch or to 2 separate switches.

EAN 4260194732118 / 25

Sensor with 4 or 8 digital inputs

The SIENNA SM8 sensor has 8 digital inputs (low voltage input) for use with multiple-gang push switches. This sensor switches 8 loads or 4 motors. Each channel can be configured independently!

Low voltage inputs: potental-free switching elements required!

8 binary (internal low voltage) inputs (0, 1, 2, …, 8) for use with multiple-gang switches. SIENNA SM4 sensor is similar to SM8, but has 4 inputs for 4 channels. Each channel can be configured individually!
Dual-switch mode: For controlling a max. of 4 motors

Single-switch mode: Pushbutton / Surge relay, On/Off; for controlling a max. of 8 loads.

Sensor with actuator-status display

The SIENNA SM1L+R Sensor sensor has one 230V input similar to SM1L. One switched 230V output (max. 1A) indicates the status of the corresponding actuator.

One binary input (L, 1) with 230V / ~50Hz. Can also be used with switches that have an integrated control light.
Switched 230V output (L’, N) for displaying actuator status. N is bridged to the neutral of the power supply.

SM3

SM3

SM3-ST02-H02

EAN 4260194732064

Sensor with 3 digital inputs

The SIENNA SM3 sensor has 3 binary inputs (internal 5V) for connecting to a 2-gang or 3-gang switch (Blind, Shutter: Up, Down, Stop). Centralized switching functionality (Master-On, Master-Off) can also be implemented with SM3.

Potential-free switching elements necessary (Low voltage inputs)!

Three binary (internal 5V) inputs (blue, red, orange, yellow).

Blue common ground

Red / Orange Up (Master switch: On) / Down (Master switch: Off)

Yellow depends on operating mode

0 additional Stop functionality.

1 Manual (overrides actuator setting). Input 3 as in mode 2.

2 Go up and block as long as the input is closed (wind / rain sensor).
