Product Details

1. Product Overview

The PR500 is a GE Fanuc (General Electric Automation) Programmable Relay Unit (PRU), positioned between hard-wired relays and a mid-size PLC. It integrates CPU, power supply and digital/analog I/O in a modular design that can be expanded with additional I/O modules for machine sequencing, simple process interlocking, timing/counting and data acquisition.

Users program it in IEC 61131-3 standard ladder logic, with built-in timers, counters, comparators and arithmetic functions. The modular architecture lets you mix digital and analog channels and communicate with HMIs or SCADA over serial/Ethernet.

The specific unit PR500UFXX55H10DTC is a configured order; its exact I/O channels, supply voltage and comms ports depend on the order suffix and must be confirmed against the GE factory configuration sheet or nameplate.

6. Why Choose Us

Exact model verification: We check supply against your full order number PR500UFXX55H10DTC and confirm it is a GE Fanuc Programmable Relay Unit, not a grid protection IED.
Transparent configuration: For options that cannot be decoded from public sources, we state so honestly and recommend confirming against the nameplate/factory sheet rather than inventing I/O counts.
Authorized channel supply: GE Fanuc products through regular channels, with documentation available on request.
Delivery & after-sales: Quotation, lead-time confirmation and order follow-up provided; to confirm exact I/O, power or comms, please email us.

7. FAQ

Q1: Is the PR500UFXX55H10DTC a grid protection relay?

A: No. The PR500 is a GE Fanuc Programmable Relay Unit (PRU) — a small programmable controller for ladder-logic sequencing and interlocking. GE grid protection relays are the Multilin 850/350/F650/T35 families.

Q2: How many I/O points does it have?

A: The I/O count is set by the order suffix; no public digit-by-digit option key exists, and reseller figures are inconsistent. Confirm exact channels against the GE factory configuration sheet or nameplate; please email us to verify.

Q3: What programming language is used?

A: IEC 61131-3 standard ladder logic, with built-in timers, counters, comparators and arithmetic.

Q4: What communication ports are available?

A: The PR500 family supports serial/Ethernet; the exact port count and protocols (e.g. Modbus) depend on the order code. See the nameplate or factory sheet.

Q5: What is the supply voltage?

A: Per order code, commonly 24V DC class; confirm from the nameplate. Please email to verify.

Q6: How do I confirm this unit's actual configuration?

A: Please send a photo of the nameplate or the GE factory configuration sheet; we can help verify I/O, power and comms. Otherwise, please email us.
