  • 12 to 36V DC
  • High-speed RS-485
[DISPLAY_ULTIMATE_PLUS]

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)
