Product Description:
The CFL01.1-Y1 is a plug-in memory module manufactured by Bosch Rexroth Indramat for the CFL Modules series. Designed for installation on the control rack system bus, the unit supplies high-speed working memory so that PLC or motion firmware can process variables, buffers, and alarm logs without delay. By storing time-critical data inside the cabinet instead of on a remote server, it supports coordinated axis control, encoder evaluation, and preventive maintenance tasks common in automated machining, packaging, and material-handling lines. Local memory access also helps the control platform update motion states and internal diagnostics without network-dependent delays.
It contains 8 MB of addressable space implemented with low-latency SRAM, giving the controller random-access times suitable for sub-millisecond scan cycles. The module draws 300 mA from the system bus and, with a dissipation of only 1.0 W, makes minimal impact on cabinet cooling calculations. Logic circuits are powered from a stabilized 3.3 V rail provided by the backplane, and the retention circuit is supported by a CR2450 3 V lithium coin cell that preserves data when the main supply is absent. Because the supply source is the common bus, no external wiring or fusing is required, which helps prevent mismatched ground potentials.
Environmental and mechanical limits support reliable operation in typical industrial settings. The enclosure carries an IP20 rating, suitable for protected indoor mounting where conductive debris is absent. Continuous service is permitted at altitudes up to 2700 m, allowing installation in high-elevation production sites without derating. Stable function is maintained across an ambient range of +5 to +55 °C, and the electronic assembly withstands 15 g of shock during handling or panel vibration. Compact dimensions of 120 mm height, 20 mm width, and 70 mm depth simplify slot allocation beside I/O and communication cards.
