Schneider Electric Modicon Momentum 171CBU98090 Unity M1E Processor Module
The Schneider Electric Modicon Momentum 171CBU98090 is a Unity M1E processor module designed for the Modicon Momentum automation platform. It features a Spear 320s 333 MHz processor with 3584 kB of program memory capacity, handling up to 2,048 discrete inputs and 2,048 outputs. Powered by a 5 V DC supply, it provides integrated processing, communication, and local I/O handling for compact distributed control architectures.
Processing Capacity and Memory Specifications
The module runs on a 32-bit Spear 320s processor architecture operating at a clock speed of 333 MHz. It supports 3584 kB of user program memory for both IEC and LL984 programming languages, alongside 26,048 register words for data storage. Program configuration and advanced diagnostics are managed through Unity Pro software, supporting safe I/O operating modes and web-based monitoring capabilities.
Communication Interfaces and Network Connectivity
Equipped with multiple communication ports, the processor supports Modbus TCP over 10/100 Mbps Ethernet via an RJ45 connector, as well as Modbus RTU serial communication over RS232/RS485 through an RJ45 port. It also includes USB connectivity and an internal I/O bus interface for direct expansion. Ethernet connections utilize CAT 5E UTP cabling for reliable plant network integration.
Physical Dimensions and Environmental Ratings
Designed for DIN rail mounting inside control panels, the module features an IP20-rated enclosure measuring 60.6 mm × 144 mm × 53.47 mm (H × W × D) and weighs approximately 0.163 kg. It operates within an ambient temperature range of 0 deg C to 60 deg C, supports storage temperatures from -40 deg C to 85 deg C, and handles relative humidity levels up to 96% (non-condensing).
