Auxiliary analog input supply voltage

An auxiliary supply voltage for the analog inputs can be configured using the MICT. The voltage can be set in the range of 5 to 24 V and is made available on the connection Analog Power. Refer to the section Timing – Analog Inputs.

   

Wiring MIC3+ ignition controller and DetCon detonation control system

The following diagram shows an example of the wiring of a MIC3+ ignition controller with a DetCon detonation control system in cases where the analog current signal (4-20 mA) at the output I out is to be used for the ignition timing adjustment.

Furthermore, the limits of the analog current input will need to be set at 4 mA to 20 mA and the auxiliary supply voltage of the analog inputs to 24 V in the MICT. Refer to the section Timing – Analog Inputs.

The timing is transmitted by MIC3+ via the auxiliary synchronization output (ASO) to the DetCon, and will need to be wired and configured accordingly. Refer to the section Output Wiring – Binary Outputs (Go/NoGo, GPO, ASO).

   

General purpose input GPI

The general purpose input GPI can be assigned various functions via the configuration. Refer to the section Inputs/Outputs – Inputs.
