X20CM0985 selection record: energy-measurement and synchronization module and installed-system fit
X20CM0985 belongs to the B&R X20 automation system. Specify X20CM0985 by its complete designation and documented role; the visible similarity of two modules is not a compatibility decision.
Identification matrix
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | X20CM0985 |
| Voltage measurement | Up to 480/120 V AC input ranges |
| Current measurement | Three 1 A or 5 A AC transformer inputs |
| Functions | Multi-measurement and mains synchronization |
The values above identify X20CM0985 at catalog level. Verify the installed revision, label and current manufacturer manual before issuing a purchase order or approving a design change.
02 / Fit boundary
When replacing or adding X20CM0985, Check CT ratio and polarity, voltage connection, isolation, terminal-block set and safety rules. The -1 version adds software functions and is a separate configuration reference.
Check X20CM0985 against the as-built wiring, X20 base, terminal block, supply module and controller software. Keep every accessory and revision difference visible in the RFQ; do not approve a look-alike solely from a photograph.
01 / Intended duty
For X20CM0985, Use the module where power measurement and mains synchronization must be engineered together.
Capture the actual cabinet location, connected equipment, expected operating range and the consequence of a lost signal or network connection. These details turn the X20CM0985 code into a specific engineering requirement.
03 / Acceptance record
For commissioning X20CM0985, Compare measured voltage, current, phase and synchronization state with independent reference instruments.
Record date, test conditions, observed LEDs or diagnostics and as-left configuration for X20CM0985. Restore normal control after testing and obtain the site's electrical or safety sign-off where required.
Code alternatives and exclusions
