The FBM239contains 16 discrete input and 16 discrete output channels that are
compatible with voltages and currents commonly found in industrial plants. An
external power supply is used to energize the field circuits.
The FBM239Discrete 16DI/16DO Module provides 16 digital inputs with 16 digital
output channels. Associated Termination Assemblies (TAs) and Termination Assembly
Adapters (TAAs) provide for discrete nominal inputs of 30 V dc, 60 V dc, 120 Vac/125
Vdc, or 240 Vac andnominal outputs of 60 V dc, 120 Vac/125 V dc, or 240 Vac. The
module performs signal conversion required to interface the electrical input signals
from the field sensors to the Module Fieldbus.
Depending on the type of I/O signal required, the TAs or TAAs support current limiting
devices, high voltage attenuation circuits, optical isolation, and external power source
connections.
Whenconnected to the appropriate Termination Assembly Adapters (TAAs) or TAs,
the FBM239 module provides functionality formerly provided by the 100 Series
Fieldbus Module (FBM) I/O subsystem. TAAs and TAs are available which support the
functionality of the main FBM09, FBM10, FBM11, FBM26 and FBM41 (8 input/8
output main FBMs). These main FBMs may be used with expansion FBM14, FBM15,
FBM16, FBM27, or FBM42(8 input/8 output expansion FBMs).
• 16digital input channels, used for either contact sensing, or dc voltage monitoring
• 16digital output channels, used for either dc output switching with an external
source (e.g. to control powering of various external loads), or dc output switching
with an internal source only (e.g. to power external solid state relays or other
similar devices)
