An integrated real-time clock complements the controller functions. This particular version is supplied with 24 V DC across a range of 19.2 to 30 V DC. Total useful secondary power is 16 W. Intern, 20 KWords of RAM are available for data. With a PCMCIA card, 128 KWords for program and data and 128 KWords of data storage are specified; an additional 15 KWords of flash data storage are listed. The application structure comprises one fast task, one master task and 16 event tasks. These memory values and task counts are technical data of this specific Modicon controller base. For mechanical identification, the relevant dimensions are a width of 341.4 mm, a height of 151 mm and a depth of 152 mm. Product weight is 1.72 kg. The documented operating range extends from 0 to 60 °C, while the storage range extends from −25 to 70 °C. During operation, relative humidity is specified at 5 to 95 percent without condensation, with an operating altitude up to 2,000 m. The complete TSX3721101 identifier, 24-V-DC supply, three slots and stated communication connections are key identity features of this version. It mounts on a panel or mounting plate.
