TECHNICAL REFERENCE
PTO Certified
- Unit certified by the ProfiBus Trade Organization.
Safety Agency Approvals & PTO Certification
– CE, UL, & cUL listed,
plus Class 1; Division 2; Groups A, B, C, D approvals.
Fully Independent Slave w/ Direct I/O Connection
– Self-contained
unit does not require special bus couplers, power supply, or rack mount
to operate.
Plug-In Terminal Blocks & DIN-Rail Mount -
Make mounting, removal,
and replacement easy.
Industry Standard ASIC
– Uses Siemens SPC3 intelligent ASIC to talk
ProfiBus.
Isolated RS485/ProfiBus Network Interface
– Highly immune to noise
and can operate over long distances. Allows many modules to network
together.
Auto-Baud Rate Detection
– The baud rate is set automatically.
High-Speed Data Rates
– Half-duplex RS485 up to 12M baud.
Includes RTS Support
– ProfiBus interface includes the optional RTS
(Request-To-Send) direction control.
Flexible Multi-Range Analog Inputs
- Accepts either DC current or DC
voltage, according to model number.
Range Variability
– The first 3 channels must share the same range,
but this can be different than the range of the last 3 channels.
Optional AC Current Input (961PB Only)
- An optional AC current
sensor can be purchased separately to support AC current inputs.
Precise High-Resolution A/D Conversion
– Modules use high-
resolution, low noise, sigma-delta analog-to-digital conversion for high
accuracy and reliability.
Nonvolatile Reprogrammable Memory
– Allows the functionality of this
device to be reliably reprogrammed thousands of times.
Fully Isolated
– Input channels (as a group), network, and power are all
isolated from each other for safety and increased noise immunity.
LED Indicators
– A green LED indicates power. A yellow bus status
LED indicates proper network connection.
Watchdog Timer Built-In
– Standard for the ASIC and operates in the
data exchange mode if communication with the master is lost.
Self-Diagnostics & Diagnostic Watchdog
- For easy maintenance
and troubleshooting. Includes a hardware watchdog timer built into the
microcontroller that causes it to initiate a self reset if the controller ever
“locks up” or fails to return from an operation in a timely manner.
Wide-Range DC-Power
– Diode-coupled for use with redundant
supplies, and/or battery back-up.
Hardened For Harsh Environments
- For protection from RFI, EMI,
ESD, EFT, & surges. Has low radiated emissions per CE requirements.
Wide Ambient Operation
– Reliable over a wide temperature range.
