Product Description:
The BTA20.4-ND-HP-VB-BS terminal block from a product listing of BTA20 Machine Control Boards series include four number of poles which accommodates multiple circuit connections in a compact assembly. This module represents a DIN‑rail mounting that simply secures the block firmly in standard control panels and streamlines further installation and replacement. A 20 Ampere current rating delivers ample power distribution for heavy loads, supporting robust actuator and motor supplies.
This Bosch Rexroth’s device allows a voltage rating of 600 V to withstand high‑potential circuits and hence it ensures safe operation in power distribution environments. Compatibility with 10-22 AWG wire gauges accept a broad range of conductor sizes for limiting the need for adapter terminals. Polyamide (PA66) housing material meets mechanical strength requirements that can resist wear in industrial settings. This control board comes with a flame rating UL94 V‑0 to prevent flame propagation under fault conditions, enhancing overall panel safety. Wide working temperatures of this machine unit, ranging from -40°C up to +105°C guarantees reliable performance across extreme environments. Screw‑type termination style ensures secure conductor clamping which eliminates loose‑connection risks during vibration. The inclusion of end bracket accessory delivers stable end‑of‑row support which preserves alignment under heavy wiring loads.
Insulation voltage of 1000 V AC isolates adjacent circuits to safe dielectric breakdown in multi‑voltage assemblies. UL, CSA, and VDE approvals meet global compliance with North American and European safety standards, thus ensures global deployment. It allows communication via INTERBUS‑S/BT‑BUS interfaces with relevant machine‑control boards, providing seamless exchange of data. An I/O width with standard BTA20 series data formats that simplifies programming and diagnostics. Additionally, emergency‑stop circuits using this board meet EN 60204‑1 requirements that allow secures operator safety in fault scenarios.
Frequently Asked Questions about BTA20.4-ND-HP-VB-BS:
Q: Which mounting does the BTA20.4-ND-HP-VB-BS uses for installation?
A: DIN‑rail mounting provides a standardized fastening method for rapid installation. It secures the block without extra brackets and supports quick replacements.
Q: How does a 20 A current rating benefit the BTA20.4-ND-HP-VB-BS?
A: A 20 A rating supports high‑power loads such as motors and heaters directly. This capacity reduces the need for external fuses in many applications.
Q: What advantage does a 600 V voltage rating deliver to BTA20.4-ND-HP-VB-BS terminal block?
A: A 600 V rating permits use in high‑voltage distribution panels and provides tolerance to maintain safe operation under elevated line potentials.
Q: Why is 10–22 AWG compatibility important for this terminal block?
A: Supporting 10–22 AWG wires accommodates a wide conductor size range. This flexibility reduces stocking of multiple terminal‑block variants.
Q: How does PA66 housing material support industrial use?
A: Polyamide (PA66) offers high mechanical strength and chemical resistance. This material endures harsh factory environments without cracking.
