Digital input modules

• 8-channel digital input module DI NAMUR EEx i, for evaluation of NAMUR sensors, connected and non-connected contacts, as well as for use as counter or frequency meter
  Parameterizable connections:
  • NAMUR sensor on/off
  • NAMUR changeover contact
  • Single contact connected (mechanical NO contact)
  • Changeover contact connected (mechanical changeover contact)
  • Single contact non-connected (mechanical NO contact with single contact)
  • Changeover contact non-connected (mechanical changeover contact)
  • Counting function: optional use of 2В channels for recording counter pulses or for frequency measurement
  • Short-circuit and wire break monitoring

Digital output modules

• 4-channel digital output modules DO EEx i, 23.1В V DC/20В mA, 17.4В V DC/27В mA , 17.4В V DC/40В mA or 25.5В V DC/22В mA, with external actuator switch-off via High or Low signal (H/L switch-off)
  • Load-free switching of outputs via external intrinsically-safe signal
  • Power boosting through parallel connection of two outputs for one actuator with 4В DO 17.4В V DC/27В mA or 4 DO 17.4 V DC/40В mA
  • Short-circuit and wire break monitoring
• 2-channel digital output module DO Relay EExВ e, e.g. for switching solenoid valves, DC contactors or signaling lamps
  • Can be plugged onto TM-RM/RM terminal module
  • Output current up to 2В A with 60В V UC for each of the two relay outputs
  • Installation up to Ex zone 1
  • Intrinsically-safe and non-intrinsically-safe signals can be mixed in a station

Extra functions

Actuator shutdown function of the 4В DO EExВ i modules

The 4В DOВ EExВ i modules are equipped with a shutdown function. This permits implementation of an external switch-off independent of the automation system (controller).

As soon as the intrinsically-safe switch-off signal (High or Low) is present at the actuator switch-off input of the electronics module, its outputs are deactivated.

You can also combine several DO modules into a switch-off group. The intrinsically-safe power supply for the switch-off device is either via the watchdog module or a separate intrinsically-safe source.
