Overview
Upgrade your ABB ACS310, ACS350, or ACS355 variable frequency drives with the MUL1-R1 conversion kit (SKU: MUL1-R1). This essential hardware accessory from ABB Low Voltage Drives transforms the standard fingersafe protected chassis into a NEMA 1 enclosure, specifically designed to accommodate conduit landings. This kit is compatible with frame sizes R0 through R2, providing a crucial upgrade for applications requiring protected environments where direct conduit entry is necessary. The NEMA 1 rating ensures protection against solid foreign objects, making your drive installation suitable for a broader range of industrial settings. The MUL1-R1 kit simplifies installation by offering a purpose-built solution for meeting NEMA 1 enclosure standards. Ensure compatibility and quality by using this direct accessory from ABB. This conversion kit is manufactured in the US.

FMK-A-R1
R1 Flange Mounting Kit for the ACS550 drives allows mounting the drive with the heatsink external to a 3rd party enclosure. Use of the flange kit requires removal of the drive cover, reducing protection to IP00. R1 through R4 flange kits can be used with 3rd party UL Type 1 & 12 (NEMA 1 & 12) enclosures.
RDCO-03C-KIT
The RDCO-03 module includes the connectors for fiber optic DDCS channels CH0, CH1, CH2 and CH3. The usage of these channels is determined by the application but are normally assigned to the following: CH0 – overriding system (e.g. fieldbus adapter) - 5 MBd. CH1 – I/O extensions - 5MBd. CH2 – Master/Follower link - 5 MBd. CH3 – PC tools (such as DriveWare) - 5 MBd.
RCNA-01-KIT
The ControlNet network uses a RG-6 quad shielded cable or fiber with support for media redundancy. The RCNA-01 Adapter module supports only RG-6 quad shielded cable (coax) for the bus connection. ControlNet is flexible in topology options (bus, tree, star) to meet various application needs. The fieldbus speed is 5 Mbits/s. The RCNA-01 ControlNet Adapter module can not originate connections on its own, but a scanner node can open a connection towards it. The ControlNet protocol is implemented according to the ControlNet international specification for a Communication adapter.
MTAC-01
The Pulse Encoder Interface module offers a differential or single ended interface for a digital pulse encoder connection. The module is capable of operating from either a 15 or 24 VDC signal with a maximum frequency of 200kHz. This option can only be used with IP20 models.
