3. Produktet er slutview
The Zelio SR2B121B is a compact logic relay designed for simple automation applications. It features a built-in display for programming and monitoring, along with multiple inputs and relay outputs.
Figure 1: Schneider Electric Zelio SR2B121B Logic Relay. This image displays the Schneider Electric Zelio SR2B121B logic relay. It features a green backlit LCD screen showing a programming sequence (I1-I2+I3+I4-I5-CC1, Z1, Z2-C1-I1, Z3). Above the screen are screw terminals for 24VDC power (+, -) and inputs I1-I4 (24VDC) and IB-IE (Analog or 24VDC). Below the screen are four gray navigation buttons and a green 'Menu/Ok' button. The bottom section shows output terminals Q1-Q4, labeled as Relay 8A.
3.1. komponenter
- Vise: Integrated LCD for programming, status monitoring, and diagnostics.
- Navigationsknapper: Bruges til at navigere i menuer og justere parametre.
- Menu/OK-knap: Bekræfter valg og åbner menuer.
- Inputs (I1-I4, IB-IE): Terminals for connecting sensors and control signals. I1-I4 are 24VDC digital inputs. IB-IE can be configured as analog or 24VDC digital inputs.
- Resultater (1.-4. kvartal): Relay outputs for controlling external devices, rated at 8A.
- Power Supply Terminals: For 24VDC power input.
4. Opsætning
4.1. Montering
The Zelio SR2B121B is designed for DIN rail mounting. Ensure the DIN rail is securely fastened in a suitable enclosure, providing adequate ventilation and protection from environmental factors.
- Hook the top edge of the relay onto the DIN rail.
- Press the bottom edge of the relay firmly until it clicks into place on the DIN rail.
4.2. Ledninger
All wiring should be performed with the power supply disconnected. Use appropriate wire gauges for all connections.
- Strømforsyning: Connect the 24VDC power supply to the designated '+' and '-' terminals. Observe polarity.
- Indgange: Connect sensors or control switches to the I1-I4 and IB-IE terminals as per your application's logic. Refer to the programming section for input configuration.
- Udgange: Connect the loads (e.g., contactors, indicator lights) to the Q1-Q4 relay output terminals. Ensure the load current does not exceed the 8A rating per output.
5. Betjening
5.1. Første opstart
Once wiring is complete and verified, apply 24VDC power. The display will illuminate, and the device will initiate its startup sequence.
5.2. Skærmnavigation
Use the navigation buttons (up, down, left, right arrows) to scroll through menus and parameters on the LCD. The 'Menu/Ok' button is used to enter sub-menus or confirm selections.
5.3. Programmering
The Zelio SR2B121B can be programmed directly via its front panel display. The programming interface allows for the creation of logic functions using a ladder diagram or function block diagram approach. Consult the detailed programming guide available from Schneider Electric for comprehensive instructions on creating and uploading programs.
- Press the 'Menu/Ok' button to access the main menu.
- Navigate to the 'Program' or 'Edit' section.
- Use the arrow buttons to select inputs, outputs, timers, counters, and other function blocks.
- Confirm each step with the 'Menu/Ok' button.
- After programming, save and transfer the program to run mode.
5.4. Overvågning
The display can show the real-time status of inputs, outputs, and internal variables. Navigate to the 'Monitor' or 'Status' menu to view disse værdier.
6. Vedligeholdelse
The Zelio SR2B121B is designed for minimal maintenance. Regular inspections are recommended to ensure optimal performance.
- Rensning: Brug en blød, tør klud til at rengøre enhedens yderside. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Forbindelser: Kontrollér regelmæssigt alle ledningsforbindelser for tæthed og tegn på korrosion.
- Miljø: Sørg for, at driftsmiljøet holder sig inden for de angivne temperatur- og fugtighedsgrænser.
7. Fejlfinding
