HIMA F7131 high-reliability power supply monitoring module

HIMA F7131 is a high-reliability power supply monitoring module, mainly used to monitor the power supply status of safety instrumented systems (SIS) and other industrial control systems. It is equipped with a buffer battery and redundant design, which can trigger alarms or switch to backup power in time when the power supply is abnormal, and is widely used in petrochemical, electric power and other key industrial fields. The detailed information is as follows:

Core Technical Parameters

Parameter Category	Specific Details
Electrical Parameters	The mainstream input and output voltage is 24V DC, and some models can output 0 - 10V DC. It can monitor the 5V system voltage generated by up to three power supplies, and the monitoring resolution can reach 1mA. Its own current consumption is about 50mA, which has low power loss. It supports three 24V outputs to monitor the status of power supply modules, and can be expanded to monitor more power supplies with the B9361 assembly kit.
Buffer Battery Performance	It is equipped with a buffer battery. Different models have different backup durations. The backup time of some models can reach 30 minutes, and it can switch to battery power supply within milliseconds when the main power fails to avoid system downtime. The charging time of the buffer battery is about 10 hours, which can quickly restore the standby capacity after the main power supply is restored.
Physical & Environmental Indicators	There are differences in size and weight among different models. The common size is about 100×50×25mm, and the weight ranges from 0.15kg to 2kg. The protection level is IP20, which is suitable for cabinet installation and supports panel or DIN rail mounting. The working temperature of most models is -20°C to 60°C, and some models can work in the environment of -40°C to 70°C, adapting to the harsh temperature changes of industrial sites.

The company has multiple main brands, and if you have other brand requirements, you can also send them to customer service for inquiry.
