BECKHOFF Automation  has extended its vast portfolio of Bus Terminal solutions with the addition of manual operating modules for mounting on the outside of control cabinet doors.

BECKHOFF’s digital and analogue I/O modules enable the convenient operation and observation of process data as well as easy manual intervention without opening the control cabinet. Available for all common bus systems using corresponding Bus Couplers, the manual operating modules can be integrated into the overall Bus Terminal system via K-Bus extension technology from BECKHOFF.

Mounted on the control cabinet door using a snap-in system, the function modules are available in four types:

  • KL8519 16-channel digital input: signal module
  • KL8528 8-channel digital output: changeover between manual and automatic mode, setting of outputs
  • KL8528 4 x 2-channel digital output: changeover between manual and automatic mode, setting of 2-stage output
  • KL8548 8-channel analogue output, 0…10 V: changeover between manual and automatic mode, analogue set value specification via potentiometer
Key features of BECKHOFF’s manual operating modules:

  • Configurable via TwinCAT automation software from BECKHOFF
  • Various functions can be individually parameterized via function blocks
  • Power and error LEDs indicate the status of the modules
  • All switch positions of the output modules are available in the controller as process variables
  • Allows manual operating level prescribed in many specifications according to VDI 3814 to be realised with no further auxiliary products
  • Up to 31 KL85xx modules can be connected to the Bus Terminal system via the K-bus extension
  • Maximum distance between the individual KL85xx modules is 5m
  • Can be integrated via the Bus Couplers into almost all bus systems such as Ethernet, EtherCAT or PROFIBUS
  • I/O level wired via the KL9309 signal-independent adapter terminal using ribbon cable or shielded round cable
