Introduction

1.Functions

F7131 Power Supply Monitoring Module

Multi-channel voltage monitoring: Simultaneously monitors up to three 5V system power supplies and three auxiliary 24V power supplies in the safety rack.
Buffer battery management: Built-in lithium buffer batteries to retain CPU RAM data and safety logic status during main power loss. Prevents loss of program and fault records in power failure events.
Diagnostic & alarm function: Detects overvoltage, undervoltage, low battery and circuit faults; transmits diagnostic test bits to central CPU (F8650 / F8651). Front LED indicators show real-time power health status for field maintenance. www.plcva.com
SIL 3 safety compliance, meets IEC 61508 functional safety standard.

F7133 4-Fold Power Distribution Module

4 independent 24VDC output channels, distributes main 24V system power to safety I/O modules and field instruments.
Per-channel overcurrent & short-circuit protection. Fault on one single channel will be isolated and cannot crash the whole safety rack, realizing fault segregation.
Standard plug-in card structure, installed in HIMA subrack. Provides stable power supply for safety I/O sub-systems. www.plcva.com
Supports safety system diagnostic feedback for power branch status.

2. Applications

Both modules are core infrastructure power cards for SIS Safety Instrumented Systems, compatible with HIMA H41q / H51q HIQuad safety controller racks. www.plcva.com

Typical System Scenarios:

ESD Emergency Shutdown System
F&G Fire & Gas Detection System
HIPPS High Integrity Pressure Protection System
Burner Management System (BMS)

Main Industries: Oil & gas, petrochemical, chemical, power plant, pharmaceutical and other high-risk process industries that require SIL3 safety protection.

Core Purpose: F7131 monitors rack power quality and keeps safety system data intact during power outage. F7133 distributes protected 24V power to each I/O branch. Together they guarantee stable, fault-isolated power supply for safety logic solver and field I/O. They prevent unsafe state caused by power abnormality, ensure safety protection actions can be triggered reliably when dangerous process conditions happen. Widely used for new SIS project configuration and spare replacement of existing HIMA safety racks.
