Product details

Rack-powered CPU for clean cabinets

The BMXP3420302: Rack-powered processor for Modicon M340: internal supply keeps external PSU off the panel floor — a particle-neutral choice for cleanroom control cabinets. CANopen bus handles up to 63 slaves; Ethernet TCP/IP for SCADA uplink. Supplied memory card (BMXRMS008MP) backs up programs, constants, symbols and data. Internal RAM totals 4096 kB (3584 kB program + 256 kB data).

Bus and performance profile

CANopen master interface (SUB-D 9) runs at selectable rates from 20 kbit/s to 1 Mbit/s, supporting daisy-chain or tap junctions per DS 301 V4.02. Ethernet port is 10BASE-T/100BASE-TX with Modbus TCP messaging and SNMP. Execution time: 0.12 µs per Boolean instruction, 0.17 µs double-length words, 0.25 µs single-length words, 1.16 µs floating point. Mixed Boolean/fixed arithmetic throughput: 6.4 Kinst/ms at 65/35 ratio. Discrete I/O capacity: 1024 local; analog: 256 channels. Supports up to 4 racks and 2 Ethernet communication modules.

Marked CE, UL, CSA, RCM, EAC, UKCA, China RoHS, WEEE. Complies with IEC 61131-2, IEC 61010-2-201, UL 61010-2-201, CSA C22.2 No 61010-2-201, IACS, EN/IEC 61000-6-5 (interface type 1 & 2), EN/IEC 61850-3 (location G). Operating ambient temperature 0…60 °C, relative humidity 5…95% non-condensing. IP20 protection.

Sourcing and fit for BOM

Internal power supply via rack simplifies panel wiring: no external DC supply to source. Module draws 135 mA at 24 V DC from the backplane. Sized for a Modicon M340 chassis; replace-in-kind for existing M340 processor slots. Supplied with memory card — verify card size matches your application needs (8 MB included).
