1.5 About the transmitter
The SmartLine Wireless Transmitter is furnished with an ISA100.11a-compliant wireless
interface to operate in a compatible distributed ISA100.11a wireless
system. The transmitter will
interoperate with any ISA100.11a wireless network.
The transmitter includes ISA100.11a-compliant electronics for operating in a 2.4 GHz wireless
network. It features function block architecture and instantiable input channels.
The SmartLine Wireless Temperature and Universal I/O Transmitters come in three models for
applications involving these I/O types:
1. T/C (Thermocouple)
2. mV (millivolts)
3. DI (Discrete Input, contact closure)
4. 2-Wire Resistance
5. 3-Wire RTD or Resistance (STIW400 only)
6. 0-20mA or 4-20mA current input (also refered to as HLAI) (STUW750 and STUW751 only)
7. DO (discrete output) (STUW751 only)
The Temeprature and Universal I/O transmitter can be configured, using channel instantiation,
for the following channel I/O combinations according to model number.
