SIO (Standard Inputs-/Outputs)

Every platform, every MLT analyzer or every MLT analysis module can be equipped with max. 1
SIO (see table P-1, too)!
At mounting into a platform or an analyzer the SIO 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 section 21 of this instruction.
The SIO as standard consists of:
2 galvanically isolated analogous outputs
Simultaneous 0(4) - 20 mA (± 22 mA, burden < 500 Ω) and
0(2) - 10 V (± 11 VDC, burden > 2 kΩ)
3 relay outputs
Load max. 30 V/1 A/30 W
1 serial interface (over extension card SIF)
RS 232 (standard) or RS 485 (option, 2-wire or 4-wire)
Every SIO can be upgraded on 4, 6 or 8 analogous outputs via respective SIA modules with two
analogous outputs each.
