981PB/982PB/983PB, Profibus-DP Dijital I/O Modül ( 12 Kanal )
12-Channel I/O
• Active-Low Inputs, Sinking Outputs
• 12 input channels, 0 to 35V DC range
• 12 to 36V DC
• High-speed RS-485
981PB:12 input channels
982PB:12 output channels
983PB:12 input/output channels
These modules provide an isolated Profibus-DP network interface for twelve discrete input and/or output channels. The outputs provide direct on/off, high/low, or open/close control of industrial devices. The inputs sense the status of motors, pumps, valves and other equipment. The 983PB model with tandem I/O provides output level control and status verification in one unit.
Features
• 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 loopback 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
