It draws up to 360 mA from the 5 V DC backplane bus and consumes 1.7 W typical, with a 1 to 5 Kbyte memory requirement on the CPU memory card for parameters. Rated for 0 °C to 70 °C ambient, with max 95 % humidity (no condensation), it is suited for cabinet environments with basic climate control. Configuration is done via STEP 7 with its own parameter assignment forms, and the module requires both 5 V DC and 24 V DC supplies from the backplane. This part is classified as NRND (Not Recommended for New Designs) by Siemens, meaning it is still available for existing installations but not intended for new projects.","metaTitle":"Siemens 6ES7440-1CS00-0YE0 CP 440-1 Coupling Module, NRND","metaDescription":"Siemens SIMATIC S7-400 CP 440-1 point-to-point coupling module, 1 channel, ASCII/3964(R) up to 115.2 kbit/s.
