Functional principle

The FDNL-S1204H-0142 is a compact fieldbus I/O module for DeviceNet and especially

designed for robotic systems resp. automatic

tool changers. The module is available in degree of protection IP67 and features 12 digital

pnp inputs and 4 digital 2A outputs.

DeviceNet and power supply are jointly connected via a multibus cable with M23 connection technology which was especially developed for robotic applications. The module also

features a 13-pole IP20 terminal on the bottom side. Via this electromechanical link, additional analog signals like those of the current

stabilizer are supplied to the multibus cable

(quasi-parallel wiring).

Due to the target application, the module also features an intelligent terminating resistor.

The terminating resistor is automatically connected if the roboter module is the last slave

at the DeviceNet branch. Once a further DeviceNet slave is added, the terminating resistor is automatically disconnected. Automatic

connection of the internal terminating resistor

is always carried out, if pin 15 and 16 of the

M23 coupling (OUT) are not short-circuited.

The diagnostic message of the load voltage

can be activated or deactivated via EDS parameterization.
