AmT03 - Module of 8 transistor outputs 24V/2A with PWM power decreasing

AmT03  Module of 8 transistor outputs 24V/2A with PWM power decreasing
  • 8 outputs 24V/2A
  • processor controlled PWM power decreasing for inductive loads
  • outputs controlled individually by logic signals
  • LED indication
  • can be connected to outputs of XmDo01 or XmDio01
  • protective low voltage power supply

Description

AmT03 is module of 8 transistor outputs suitable for switching 24V/2A with PWM power decreasing controlled by microprocessor. Modul can be used for inductive load switching (electromagnetic valves, conductors etc.), where fast current increase and reduced holding current are desired.

Load can be connected between output terminal and common terminal GND. Each output has switch-off diode for absorbing voltage spikes, which arises during turn-off of inductive load.

Output switching is accomplished by connecting corresponding pins INx+ and INx-, eg. by XmDo01 or XmDio01 outputs. Switching is indicated by LED.

Module or individual outputs must be protected against overload. Module loaded with max. load needs cooling by natural air flow.

Module can be mounted to frame which snaps-on to DIN TS35 rail system.
