MAXIFLEX 64DI Module Model M1327A 64 Channel 24Vdc Digital Input Module (Positive Common). DATASHEET FEATURES • Fits in any MAXIFLEX base I/O slot 64 Digital Inputs with positive common (switch to 0V). 4 off 20 way Ribbon Header connectors In system automatic module detection The M1327 64DI module provides 64 digital inputs. The input circuitry is powered externally from 24Vdc. The module may be inserted into any I/O slot in a Maxiflex system. All inputs are opto-isolated from the system logic. Inputs are connected via four twenty-way insulation displacement ribbon cable 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.
