1.10.8 DIO (Digital In-/Outputs)
Every platform can be equipped with max. 1 to 5 DIOs. Every MLT analyzer or every MLT analysis
module can be equipped with max. 1-2 DIOs (see table P-1, too)!
For maximum assembly with DIOs (5 or 2 DIOs resp.) there is no place for SIO PCB!
At mounting into a platform or an analyzer the DIO serves system functionallity of I/O´s and
supports all analysis modules of the NGA system.
Only the analysis module itself is supported at mounting into an analysis module.
To the programming we refer to the accompanying software instruction. The pin assigments are
described in chapter 21 of this instruction.
On DIO PCB are integrated:
◆ 8 digital Inputs,
5 - 30 VDC / 2,2 mA
Low level: 0,3 - 3,0 VDC / High level > 4 VDC
◆ 27 digital Outputs,
5 - 30 VDC / max. 500 mA
