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 MIC5 ignition controller and DetCon detonation control system

The following diagram shows an example of the wiring of a MIC5 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 MIC5 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.
