MAXIFLEX 32DO Module Model M1342A 32 Channel NPN Transistor (Sink) Digital Output Module. DATASHEET FEATURES • Fits in any MAXIFLEX base I/O slot 32 Solid State Current Sink Open Collector Outputs 100mA output current sink capability per channel 2 off 20 way Ribbon Header connectors Hot Plug-in In system automatic module detection The M1342 32DO module provides 32 solid state current sink digital outputs each capable of driving 100mA loads on a 24Vdc supply. The output circuitry is powered externally from the 24Vdc. The module may be inserted into any I/O slot in a Maxiflex system. All outputs are opto-isolated from the system logic. Outputs are available on two twenty way ribbon headers. These ribbon headers are compatible with the recommended C6320 DIN-rail mounted Termination Board as well as other OMNIFLEX products equipped with the OMNIFLEX standard ribbon header pinout such as the Omni16 annunciators and displays. The module can be inserted or removed while the system is powered. Auto-detection capability allows the CPU to recognise the presence of this module in the system.
