LED Indication
Terminating Resistor - User can connect Externally if needed at both far ends
Fail safe Resistor: Provision of internal 4k7 resistor Pull up & Pull Down on BUS.
Multi-drop capability in RS485: 32 unit Nodes without Terminating Resistor & 10 unit nodes with Terminating Resistor.
Over Current Protection: Protects against two signals (D+, D-) shorted together
1.5 KVrms Galvanic Isolation for 1 min.
Power Indication
LED ON-Power applied, LED OFF-Power not applied
TX LED Indication
TX LED for data from RS232 Port to RS-485/422 Port.
RX LED Indication
RX LED for from RS-485/422 Port to Rs232 Port.
RS 232 to RS 485/422 Convertor, 28B21A0 has compact modular,
Din Rail Mounting type construction. This is an externally powered
which facilitates an electrical interface between Rs232 & RS 485/422
which can be widely used by industrial automation devices that
communicate real-time, deterministic data across bus-based networks,
over extended transmission distance
Terminating Resistor: "120 OHM RESISTOR"has been
provided in polythene bag, along with the product.
Not connected in device. If needed user can connected it
externally at both far ends.
