FAQ 

1.25B-D024N114 Does it have a built-in dynamic braking transistor? What accessories are needed to achieve braking?

The Built-in dynamic braking transistor (braking chopper IGBT), only an external braking resistor is needed. It can be directly connected to the braking terminal of the inverter to complete energy consumption braking.

2.25B-D024N114 board supports what type of Ethernet communication and which types of ring network topology?

Supported. The

• On-board communication: Embedded EtherNet/IP industrial Ethernet with dual network ports hardware.
• Supports ring topology: DLR (Device Level Ring), featuring single-link fault redundancy capability, ensuring uninterrupted communication even if a single point of the line is disconnected.

3.How many digital output and analog output terminals are built-in in 25B-D024N114?

The

• 2 Digital output using optocoupler transistors (high-speed pulse / switch quantity)
• 2 Relay contact output (1 normally open Form A, 1 normally closed Form B)
• Analog output: 1 channel (0–10V / 4–20mA jumper switch)

4.What are the overall dimensions and net weight of Model 25B-D024N114?

The

• Overall machine dimensions (height × width × depth) 305mm × 130mm × 212mm
