Product description
Leitungsabschlussgerät mit Abschlusswiderstand,
zum aktiven Busabschluss von RS485-Netzwerken
Line termination device MODKON® LA-Modbus -T3 with terminating resistor, in impact-resistant plastic housing with quick-locking screws.
The line termination serves as an active bus termination for RS485 networks (ANSI TIA/EIA-485), such as Modbus RTU. It contains a terminating resistor with a biasing network that predefines the bus level to a safe value (fail-safe biasing) during the bus idle state.
The bus termination can be completely switched on or off via DIP switches. This makes it easy to test various operating scenarios during servicing.
In the case of very long network cables, both end points can also be provided with an active bus termination to improve interference immunity under harsh environmental conditions.
