Fig. 103 MGT40 TS Module
The cables must be screened if there is a risk of excessive electromagnetic loads (Chapter 12
"Installation").
MHD TS Module (High Driver)
• The MHD uses 10 IC drivers for driving 40 capacitive or inductive outputs (output 1–4, 5–8, 9–
12 etc.).
• The drivers are over-temperature- and over-voltage-safe.
• The maximum power loss per driver is limited, the more outputs are active the less must be
the current per output.
The MHD module is an external supplement of the MGO module inverting the MGO output signal.
Unlike the MGO module (= Low Driver), the MHD assembly switches loads which are jointly
connected to GND (= High Driver).
The MHD module is connected to the rack by 40-pin ribbon cable, and thus makes 40 outputs
available (24 V/0.3 A).
40-pin ribbon cable connection at MUT (of MGO).
• 24 V supply and load connections (20 A maximum)
• Mounting on C or standard rail
• Outputs short-circuit-proof
Redundant supply must be realized externally.
