HIMA DCCM 980707 (HIQuad X Dual-Channel DC Power Supply Monitoring Module)

HIMA DCCM 980707 (HIQuad X Dual-Channel DC Power Supply Monitoring Module)
I. Basic Information
Brand: German HIMA (Black Horse), compatible with HIQuad X TMR SIL3 safety instrument system, and it is compatible with the same chassis as F-IOP01 and K9203A you previously queried.
Full model: DCCM
Original material code: 980707
Full name: Dual Current & Voltage Monitor (Dual-channel DC Voltage and Current Monitoring Card)

Model Positioning
It belongs to the dedicated power status acquisition card for HIQuad X system, installed in an independent slot vertically on the chassis, and real-time monitors two external 24VDC safety power supply circuits, providing power failure diagnosis signals to the F-CPU01 main controller to ensure the reliability of the ESD/MFT/ETS safety system power supply.

 Core Hardware Functions
Dual-channel independent 24V DC monitoring
Collects the voltage and current values of two redundant 24V safety power supplies simultaneously;
Standard monitoring range: DC 18~32V, 0~20A circuit current.
Hardware rapid alarm for over-limit conditions
Software can set under-voltage, over-voltage, and over-current thresholds; once the power supply is abnormal, the module immediately sends a fault signal to the I/O bus, and the CPU triggers system diagnostic alarms, which can be linked to the upper-level DCS alarm.
Breakdown / power loss diagnosis
Detects power circuit breakage, fuse melting, and single loss of dual power supply, distinguishes transient drops from permanent faults, avoiding system mis-termination.
TMR three-out-of-two safety voting
Board-mounted triple redundant acquisition circuit, meeting IEC61508 SIL3, single-channel acquisition failure does not affect the overall power judgment.
Local panel status indicator LED
Running, channel 1 normal, channel 2 normal, over-voltage, under-voltage, over-current comprehensive fault indicator lights, local quick location of power abnormality.

Electrical and Mechanical Parameters
System power supply: Backplane DC5V (supplied by F-PWR01 chassis power supply)
External measured circuits: Two isolated DC24V inputs, electrical isolation between channels
Installation: HIQuad X standard single-slot vertical module, supports online hot-swappable replacement, no need for safe interlock during shutdown
Environment: 0~+60℃ cabinet use, IP20 protection; TÜV SIL3, CE, Zone2 explosion-proof certification
Cooling: Compatible with K9203A (996920360) three-fan cooling module

Linkage with Upstream and Downstream Equipment (your complete query list)
Front end: Two 24VDC redundant safety power supply cabinets’ outputs are connected to the DCCM terminals;
Middle layer: Monitoring data is uploaded to F-CPU safety program via F-IOP01;
Upper layer: F-COM01 Ethernet transmits power failure signals to ABB Symphony INFI90 DCS (TRM01 optical communication card, BIO01 discrete IO chassis);
Unit linkage: Power failure can be linked to Woodward 8440-1706 parallel module, GE 760 high-voltage protection device to trigger safety shutdown.

Typical Application Scenarios Power plant boiler MFT, turbine ETS trip safety system power monitoring;
Chemical/Petrochemical ESD emergency shutdown, F&G fire gas system dual 24V power supply monitoring;
Gas/LNG station SIL3 HIPPS high-pressure protection system power redundancy diagnosis;
Comprehensive replacement of HIQuad X set of spare parts, upgrading and renovation of old H41q/H51q systems.
