E.Dold BH5932.22010 Speed Monitoring Safety Relay

Product Dimensions：

The E. Dold & Söhne BH5932.22/010 is a highly reliable Emergency Stop (E-Stop) Monitor and safety relay module from the SAFEMASTER series. It is designed to safely interrupt power circuits in industrial automation environments when an emergency stop command is triggered.

Product Detailed Description

The BH5932.22/010 is a dual-channel safety relay used to monitor emergency stop buttons, safety gates, or light curtains. The code structure indicates its configuration:

• .22: Represents the contact configuration, typically consisting of 2 NO (Normally Open) safety outputs and additional signaling/auxiliary contacts.
• /010: Denotes a specific sub-variant or specialized feature (such as a specific voltage range, cross-fault monitoring capability, or time-delay behavior).

It operates on a redundant control principle with self-monitoring, ensuring that a single internal component failure will not compromise the safety function.

Technical Parameters

Product Advantages

• High Safety Compliance: Achieves the highest safety ratings (PL e, Cat 4, SIL 3), making it suitable for hazardous machinery applications.
• Cross-Fault Monitoring: The module can detect short circuits across the emergency stop start button wires, preventing unsafe restarts.
• LED Diagnostics: Front-panel LED indicators display the state of the operating voltage, as well as the status of channels 1 and 2, facilitating rapid troubleshooting.
• Removable Terminals: Employs pluggable terminal blocks that permit swift module swapping without needing to rewire the unit.

Important Considerations & Precautions

• Nominal Voltage Verification: Dold BH series modules are manufactured for various operational voltages. Always double-check the exact side label voltage before applying power to terminals A1/A2.
• Feedback Loop Monitoring: If external contactors are utilized to expand current capability, their NC (Normally Closed) contacts must be wired into the feedback loop (Y1/Y2) to monitor for contact welding.
• Surge Protection: When switching inductive loads (such as heavy-duty contactor coils or solenoids), install external RC elements or varistors to prevent premature contact wear on the safety relay.
• Reset Configuration: Ensure whether your module is configured for Automatic Reset or Manual/Monitored Start, as incorrect loop wiring will cause the relay to lock out or self-start dangerously.

Product Applications

The BH5932.22/010 is applied across diverse manufacturing platforms to protect personnel and machinery:

• Machine Tools: Interlocking safety guards on CNC routers, lathes, and milling machines.
• Conveyor Lines: Global emergency stop line monitoring across material handling facilities.
• Packaging Machinery: Safeguarding access points on automated wrapping and boxing lines.
• Robotic Cells: Acting as the primary safety master to kill power to industrial robot arms when a perimeter gate is violated.
