GE UR9NH Control CPU Module

Q1: What role does the UR9NH play in the UR family?
A1: It is a full-featured CPU slice that executes protection, measurement, logic and communication tasks, driving 128 analog inputs and finishing each scan in 0.15 ms.

Q2: Why is the performance boost so large?
A2: A 240 MHz dual-core ARM plus floating-point DSP delivers 1.2 GFLOPS—2.4× the 8N generation—and cuts scan time by 57 %.

Q3: Does power rise with the higher speed?
A3: No. Built on a 40 nm low-leakage process, the module draws only 2.8 W fully loaded, 32 % less than its predecessor, so no extra heat-sink is required.

Q4: How fast is network self-healing on site?
A4: The on-board 10/100Base-T port supports RSTP rings that recover in <50 ms; the RS-485 port runs 9.6 k–115 k full-duplex and can host IEC 60870-5-103 and Modbus-RTU in parallel.

Q5: How many CT/VT circuits can one module handle?
A5: The local bus manages 32 CT/VT groups (128 channels) directly; cascading URTCH boards expands the total to 256, enough for a full bus-bar differential.

Q6: How is accuracy maintained in harsh environments?
A6: Operating temperature -40 °C to +85 °C, 2 kV burst and 3 kV surge tested, salt-mist for 10 years—error drift remains <0.1 %.

Q7: Is a shutdown required for firmware updates?
A7: Hot-swap and online flashing are supported. Dual-image backup keeps protection active during the upgrade, reducing MTTR to zero.

Q8: Will set-points be lost if power fails?
A8: 256 kB FRAM provides 100 trillion write cycles and 10-year retention without battery or super-capacitor.

Q9: How can I quickly verify authenticity?
A9: Each UR9NH carries an encrypted chip with a unique UUID; scan the front QR code to connect to GE’s cloud for instant validation. A factory COO and TÜV SIL report ship with every unit for double proof.

Q10: How are stock and delivery guaranteed?
A10: PLC Autocontroller (Xiamen, 20 years in automation) in stock.
