Product Description:
The BTA20.3-NC-DC-BA-BS control board is an operator interface designed for reliable signal control and interface capability. It is built by Rexroth and its products are designed to meet the highest standards of quality that work with high precision and durability.
The BTA20.3-NC-DC-BA-BS control board is enclosed with a varnished aluminum having a front panel by featuring a chemically resistant category of polyester foil that is embedded by offering resistance to wear from environmental exposure. It can support predominantly 24 V data output that operates on providing a stable 200 mA per output sufficient to meet typical automation signaling requirements. In the case of the enabling circuit, the switching current capacity provided by the current rated at 2 A DC and 3 A AC is appropriate to most typical industrial automation interface applications. The unit also has a Line 20 interface that is incorporated with modular systems. It has 3-outputs with a +5 V bus output which has been capped to a maximum of 50 mA and is used only to bus connections and internal logic devices.
The BTA20.3-NC-DC-BA-BS control board switch S2 temporarily provides separation or decoupling of the E-STOP circuits when plugging or unplugging the operator terminal to prevent accidental shutdowns. The Gray code override type switch is one of the characteristic features that enable accurate manual input control. It also has a key switch in order to make it run with authorized use and proper access to control functions. The enabling switch which applies at connector X1 has three positions deliberately disabled to ease safety logic and avoid excess signaling. The unit delivers low power as 18 watts and functions accordingly to obtain desired results.
Frequently Asked Questions about BTA20.3-NC-DC-BA-BS:
Q: What type of front panel is used in the BTA20.3-NC-DC-BA-BS unit?
A: It features a varnished aluminum front panel with a chemically resistant polyester foil, ensuring long-term protection in industrial conditions.
Q: How much current does the +5 V bus output on BTA20.3-NC-DC-BA-BS support?
A: The +5 V output for the bus connection can supply up to 50 mA, adequate for supporting internal signal communication and control modules.
Q: Can the third enabling switch on connector X1 be used in BTA20.3-NC-DC-BA-BS?
A: No, the third enabling switch on X1 is not functional and cannot be used in the board’s configuration.
Q: What is the switching current capacity of BTA20.3-NC-DC-BA-BS enabling circuits?
A: The enabling circuit supports 2 A DC and 3 A AC, accommodating both types of current switching reliably.
Q: What is the output current per channel on the BTA20.3-NC-DC-BA-BS board?
A: Each 24 V output channel provides a consistent 200 mA current, useful for stable field signal transmission.
