Product Overview
FOXBORO FBM42 is a high-power contact/DC extended input and output interface module designed for industrial automation systems and supports high current load control and digital signal processing.Its core functions include input detection,output switching,overload protection and channel isolation,and are suitable for industrial scenarios that require high current capabilities,such as process control,energy management,robot control,etc.
Core functions and technical features
1.Input/output function
Input function:
8 channels,can be configured in contact detection or DC voltage monitoring mode.
Output function:
8 channels,supports DC output switching,suitable for controlling external load power supply(such as motors,solenoid valves),rated current up to 12 A/channel(steady state).
2.Overload protection
Automatic restart mechanism:When an overload is detected(exceeding surge or steady-state current),the module will be disconnected for 64.5 line cycles and then try again,and the cycle will continue until the load is normal.
Safety Threshold:Overload current exceeding 50 A will cause permanent damage to the module.
3.Instruction and monitoring
LED status indicator:
Running status:2 LEDs(red/green)display the running status of the module.
Channel status:8 LEDs are input and output,and the channel is opened and closed in real time.
4.Physical interface
Connector:34-pin connector,compatible with Burndy MSD 34 PM series plugs(such as PM118,PM124,PM824)or other similar products.
Application voltage:Supports up to 60 V DC,with unlimited short-circuit load duration(1 second off when overloaded).
