Micro ICCS

Programmable Control Units in Relay Design

Micro ICCS are small and programmable control units packaged as a relay with 9 pins, which can be connected to the circuit board over the 9 pin relay sockets. Thanks to the MSP430 16 Bit microprocessor with flash memory, they can be used for functions such as voltage or frequency monitoring with:

One analogue input
Three digital inputs
Up to two high side power outputs (alternative one relay output)
Open collector output for signals with max 2 W

Data and Facts About the Micro ICCS

General Information
Operating temperature	-40 °C to +85 °C
Limiting continuous current (relay output)	10/15 A (NC/NO)
Quiescent current	250 µA
Ingress protection	IP 53 (for versions without potentiometer) IP 65 achievable with specific socket
e1-approval	03 3218
Dimensions	30 x 30 x 40 mm

Diagrams S3/S4: Relay contact is potential free and able to switch DC voltage
On some versions the analogue input is replaced by a build in potentiometer (pin 15 can still be used as a digital input)

Voltage Monitoring - Frequency Monitoring - Freely Programmable

Chronogram of the Micro ICCS - Voltage Monitoring

Better safe than sorry: If the load falls below or exceeds a defined threshold voltage at terminal 15, the Micro ICCS Voltage Monitor switches it off. The standard thresholds are for 12 V applications 11.5 V / 12.5 V and for 24 V applications 23.5 V / 24.5 V. As another option, the voltage thresholds can be defined by the customer. The time delay is also possible.

The range monitor (window comparator) switches off or on the load as soon as the voltage is in a certain range.

Application Examples

Battery monitoring for load lifts and touring buses
Signal limit check e.g. pressure monitoring

Micro ICCS - Circuit diagram frequency monitor

Micro ICCS Frequency Monitor switches-on or -off loads when certain threshold frequency is exceeded or falls below. The frequency thresholds can be defined by the customer, frequency range is 10-1.000 Hz. Also the combinations with delay times are possible.

The time tolerance is ±1 ms. The switching-off happens at terminal 15 (inverting is possible).

Matching circuit diagrams: S1 and S2

Application Examples

Automatic start
Rotation measurement
Flow rate

Micro ICCS can also be programmed for individual functions with the following properties:

An analogue input
Three digital inputs
Up to two high side power outputs (alternative a relay output)
Open collector output for signals with max 2 W

Application Examples

Controller for air conditioning system
Impulse stabilization and extension
Pre-heating of an engine
