1785-CHBM Rockwell Automation ControlNet Processor Backup

1785-CHBM Rockwell Automation ControlNet Processor BackupProduct Overview The Allen Bradley 1785 CHBM serves as an intelligent, high availability Hot Backup Memory Cartridge engineered exclusively for ControlNet enabled PLC 5 programmable logic controllers. This plug in hardware card establishes a redundant control loop between two matching processors, such as the PLC 5 40C or PLC 5 80C, which operate on a unified ControlNet coaxial or fiber network. Equipped with 100 Kilowords of non volatile EEPROM backup

ensuring that the control system maintains data flow even if one communication path encounters a fault

10 A @ 240 VAC (AC-15 duty) Number of Poles 4 Terminal Type Screw terminals Mounting Type DIN-rail mountable Certifications CE

Fault-Tolerant Reliability: The FBMSLT supports a dual-processor configuration

This failsafe behavior ensures actuators return to a known safe position during a system-wide control failure

the module bypasses the standard Requested Packet Interval (RPI) and controller overhead

This allows for more compact control cabinet designs and lowers overall infrastructure costs

This processor module executes critical safety logic for Emergency Shutdown (ESD)

Conductor Separation Protocols: Separate all 24 VDC safety-critical input wiring trunks from high-voltage AC lines and inductive switching loads inside the enclosure wire ducts to prevent electromagnetic noise induction

The 900B01-0001 provides laboratory-grade output precision within a heavy-industrial form factor

for 4-wire devices requiring high current

8 mA @ 10 VDC Off-State Voltage (Max) 5 V Signal Delay (Typical) 3 ms Isolation Voltage 250V Continuous (Channel-to-Backplane) Removable Terminal Block 1756-TBCH or 1756-TBS6H (36-Pin) Engineering Advantages

It includes internal circuitry for galvanic isolation and signal interfacing
