HIMA Z7128 Cable Plug Connector for Analog Input F6217

🔨Overview

The HIMA Z7128 is a DC/DC converter power supply module that converts the plant 24 V DC main supply into a stabilized 5 V DC supply for the HIMA PES H51q safety system, feeding the central unit, I/O circuits and rack backplane. It provides safe isolation between the 24 V DC input and the 5 V DC output, and integrates overvoltage protection, current limitation and a short-circuit-proof output. The Z7128 can be configured in redundant parallel operation to support high-availability safety cabinets.

5️⃣Installation and Setup Notes

• Mount the Z7128 in the designated power supply slot of the H51q rack; the module requires 8 TE of rack space
• Confirm the 24 V DC input remains within −15 % … +20 % with ripple below 15 % rpp
• Use the front-panel potentiometer and test socket to set and verify the output voltage before connecting loads
• In redundant configurations, match the two Z7128 output voltages to within 0.025 V
• Check the 6.3 A slow-blow primary fuse and run a functional test before energizing the central unit

6️⃣FAQ

Q: What does the HIMA Z7128 do? A: It is a DC/DC converter that converts 24 V DC plant power into regulated 5 V DC for the HIMA PES H51q system, with safe isolation, overvoltage protection and current limitation.

Q: What are the Z7128 output voltage and current ratings? A: The output is 5 V DC ±0.5 V, steplessly adjustable (factory preset 5.4 V DC ±0.025 V), rated at 10 A, with current limited at approx. 13 A.

Q: Can two Z7128 modules be used in parallel? A: Yes. For redundant use, their output voltages must be matched to within 0.025 V to avoid unbalanced load; the output is short-circuit proof.

Q: Is the Z7128 an AC power supply? A: No. It is a DC/DC converter with a 24 V DC input and a 5 V DC output; AC mains must not be connected directly to it.
