Product catalog summary

Overview: The NB12 bare board, part number 88970001, is designed for easy integration into mass-production applications. It supports up to 350 blocks in FBD language and 120 lines in LADDER language, featuring compact dimensions and a range of controllers for application-specific functions.

Specifications: The NB12 includes 8 digital inputs (4 of which are analogue) and 4 relay outputs, operating on a 24 V DC supply. It is certified by CE, UL, CSA, and GL, and conforms to various IEC/EN standards for low voltage and EMC directives.

Environmental Characteristics: The product is rated IP40 on the front panel and IP20 on the terminal block, with an overvoltage category of 3 and a pollution degree of 2. It operates at altitudes up to 2000 m and can be transported up to 3048 m. It is resistant to vibrations, shocks, ESD, and various electromagnetic interferences.

Operating Conditions: The operating temperature ranges from -20°C to +70°C, with storage temperatures from -40°C to +80°C. It supports a relative humidity of up to 95% without condensation.

Mounting and Connections: The NB12 can be mounted on a DIN rail or panel and supports various wire types with specific tightening torques. It includes protections against polarity inversions.

Processing Characteristics: The product features an LCD display for certain models, supports programming via function blocks or ladder logic, and has a program memory of 8 Kb. It offers a cycle time of 6 to 90 ms for FBD and typically 20 ms for Ladder.

Power Supply: The NB12 operates on 24 V AC or 100-240 V AC with specific operating limits and frequency ranges. It has built-in protections against overloads and short-circuits.

Inputs and Outputs: The digital inputs support various voltage levels and currents, with configurable response times. Relay outputs have specific breaking voltages and currents, with a mechanical life of 10 million operations.

Accessories: Available accessories include programming software, EEPROM memory cartridges, serial and USB cables, and a Bluetooth interface.

Product Adaptations: Options for tropicalization, spring or removable connectors, and updates to the number of I/O or power supply are available.
