Product short description:
  • Active-Low Inputs, Sinking Outputs
  • 12 input channels, 0 to 35V DC range
  • 12 to 36V DC
  • High-speed RS-485

981PB, 982PB, 983PB: Profibus-DP 12-Channel Digital I/O Description

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.

Input Range: 0 to 35V DC.

Output Range: 0 to 35V DC.

Network Communication: Profibus-DP, RS-485 network up to 12Mbaud.

Power Requirement: 12 to 36V DC supply required.

Approvals:
Profibus PNO certified.
CE marked. UL, cUL listed.
Class I; Division 2; Groups A, B, C, D.

Performance

Input (981 & 983 models)

Input Type:
Twelve active-low, buffered inputs, with a common connection. Built-in 5.6K ohm pullups to excitation terminal socketed for 4-channel groups.

Input Signal Voltage Range: 0 to 35V DC, maximum.

Input Impedance: 100K ohms, typical.

Input Signal Threshold: TTL compatible with 100mV of hysteresis, typical.

Output (982 & 983 models)

Output Type: 12 independent, open-drain, DMOS MOSFET switches.

Output Voltage Range: 0 to 35V DC max. (0 to 500mA/channel continuous).

Output ON Resistance: 0.28 ohms maximum.

Environmental

Ambient Temperature:
Operating: -25 to 70°C (-13 to 158F).
Storage: -40 to 85°C (-40 to 185°F).

Relative Humidity: 5 to 95%, non-condensing.

Isolation:
1500V AC for 60 seconds or 250V AC continuous.
3-way isolation between I/O, network, and power.

  • 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 (-13 to 158F)
