Nano ICCS

Small Controllers in Relay Design

The small controllers are packaged as relays with 5 or 6 pins and can be connected to the circuit board using standard relay sockets.

Thanks to MSP430 16 Bit microcontroller with flash memory, you can control functions which can be created with a digital input and relay change over contact, such as

Time Relays - Impulse Relays - Toggle Relays

Chronogram of the Nano ICCS - Switch-off Delay

You determine the delay time - Nano ICCS Time Relay - Switch Off Delay - are used to switch off a load precisely after a given time.

The supply voltage is applied to terminal 30. As soon as signal voltage is applied to terminal 15, the relay switches on immediately. If signal voltage is removed from terminal 15, the relay switches off after the defined delay time.

Application examples

Defrost
Delayed switching off of lights
Follow up control

Chronogram of the Nano ICCS - Switch-on Delay

You determine the delay time, the Nano ICCS Time Relay - Switch-On Delay - switches consumers on precisely.

The supply voltage is applied to terminal 30 (on the diagram S3 to terminal 87z). As soon as signal voltage is applied to terminal 15, the relay switches on after the given delay time has expired. If signal voltage is removed from terminal 15, the relay switches-off immediately.

Application Examples:

Compressor
Air conditioning systems
Switch-on delayed engines

Chronogram of the Nano ICCS - Switch-on and Switch-off Delay

Nano ICCS Time Relay – Switch-On and Switch-Off Delay – are used to switch on or off a load after a given time.

The supply voltage is applied to terminal 30. As soon as signal voltage is applied to terminal 15, the relay switches on after the given delay time is expired. When the signal voltage is removed from terminal 15, the relay switches off after the defined delay time.

Application examples

Chronogram of the Nano ICCS - Impulse Relay

Nano ICCS Impulse Relays are used to switch loads on and off for an individually defined time period – such as in control devices for preheating times.

The supply voltage is applied to terminal 30 (on the diagram S3 to terminal 87z). If control voltage is applied to terminal 15, the relay switches-on for the given time period and switches-off afterwards.

Diagrams S1 and S2: The duration of the input impulse has no impact on output impulse duration (this means the relay cannot be triggered afterwards).
Diagram S3: If input signal is taken away from terminal 15 before the given time period expired, the relay switches-off directly.

: If you need to switch loads on or off such as e.g. working lights via a button, you can use Nano ICCS Toggle Relays.

If a positive impulse is applied to terminal 15, the relay switches and becomes self-sustained (on or off). One more impulse and it switches again (impulse switch or toggle-flip-flop). Terminal 15 is debounced.
