Siemens 6ES5713-0AD20 Cable Connector

The Siemens 6ES5713-0AD20 Cable Connector terminates PROFIBUS cables for SIMATIC S5 systems. This connector provides a reliable 9-pin D-sub interface for bus communication. You will find it in factory automation networks across many industries. It includes a built-in termination switch for end-of-line configuration. Therefore, this unit ensures proper signal quality on long PROFIBUS segments.

The Siemens 6ES5713-0AD20 Cable Connector measures 60 mm in height and 35 mm in width. Its depth reaches 20 mm for direct cable mounting. The unit weighs approximately 0.04 kilograms. It contains one 9-pin D-sub male connector and one termination resistor. No active electronic components exist inside this connector. Additionally, you get two strain relief clips for cable security.

Internal Architecture and Energy Storage

The Siemens 6ES5713-0AD20 Cable Connector stores absolutely no electrical energy internally. It contains no capacitors or batteries at all. A small PCB connects the 9-pin D-sub pins to the screw terminals. A switchable 220 ohm resistor sits between pins 3 and 8 for bus termination. When you engage the termination switch, the resistor connects to the circuit. When you disengage it, the resistor disconnects completely. Two screw terminals accept the PROFIBUS data wires A and B. A third screw terminal accepts the shield drain wire. Two strain relief clamps secure the cable against tension and vibration.

Connection Interfaces and Wiring Details

You will find three screw terminals inside the connector housing. Connect the PROFIBUS A wire (green) to terminal 1.Connect the shield drain wire to terminal 3 (ground). Use 22 to 24 AWG stranded copper wire for all connections. The Siemens 6ES5713-0AD20 Cable Connector also includes a 9-pin D-sub male interface. This interface plugs directly into PROFIBUS ports on S5 CPUs and I/O modules. Tighten the two strain relief screws after wiring to secure the cable. Set the termination switch to ON for end-of-network devices. Set it to OFF for all middle devices on the bus.

Installation and Wiring Steps

You power off all network devices before connecting this connector. First, strip 30 mm of the PROFIBUS cable outer jacket. Then, strip 5 mm of insulation from each inner wire. . Insert the shield wire into terminal 3 and tighten the screw. The Siemens 6ES5713-0AD20 Cable Connector requires no external power for operation. Close the connector housing and tighten the two strain relief clamps. Set the termination switch according to your network position. Plug the D-sub connector into the device port. Tighten the two locking screws to secure the connection.
