12 Channel Profibus-DP Modules 981PB 982PB 983PB

These modules provide an isolated Profibus-DP network interface for 12 discrete input and/or output channels. Model 981PB offers 12 input channels; Model 982PB offers 12 output channels and Model 983PB offers 12 input/output channels.

Used to open/close industrial devices or recognise status of motors, pumps, valves, and other equipment.

The Acromag 981PB 982PB 983PB are 12 channel Digital Profibus-DP Modules.

Firstly, they offer active low inputs and sinking outputs. The outputs provide direct on/off, high/low or open/close control of industrial devices. Whilst, the inputs sense the status of motors, pumps, valves and other equipment. The 983PB has input and output I/O and provides output level control and status verification in one unit.

Secondly, these modules offer 3 way isolation between I/O, network and power. Network communication is by Profibus-DP, RS-485 network up to 12Mbaud.

Other features of the 12 Channel Digital I/O Profibus-DP Modules 981PB 982PB 983PB include:

  • Standard Profibus-DP network communication with industry-standard ASIC (Siemens SPC3)
  • 12-channel stand-alone module has far lower start-up cost than multi-piece block I/O systems
  • 0-35V DC solid-state logic interface can monitor or control a wide variety of devices
  • Bidirectional I/O models facilitate loop-back monitoring of the output state
  • Socketed SIP resistors provide input and output 5.6K ohm pull-ups to the excitation supply
  • Three selectable failsafe modes (off, last-state, or pre-defined) help prevent unsafe conditions
  • Compact packaging with pluggable terminals saves space and simplifies wiring
  • Wide operational temperature range permits installation in extreme environments: -25 to 70°C
