The FBM242 Discrete Output Module contains 16 discrete output channels, which are sourced externally, rated up to 2 A at 60 V dc. Associated termination assemblies (TAs) provide for discrete outputs to loads of 2 A at 60 V dc, relay outputs (120 V ac/125 V dc, or 240 V ac), or relay outputs with power distribution and fusing. Each output is fully isolated from other channels and ground. The module interfaces electrical output signals from a control processor to the field devices. It executes a digital I/O application program, with ladder logic support, and provides a Fail-Safe Configuration option for the outputs.

Key features of the FBM242 modules are:  Sixteen discrete outputs  Supports discrete output signals at voltages of: • 15 to 60 V dc • 120 V ac/125 V dc • 240 V ac  Each input and output is galvanically isolated; group isolated when used with external excitation  Rugged design suitable for enclosure in Class G3 (harsh) environments

 Executes the Discrete I/O or Ladder Logic program, with the following configurable options: Input Filter Time, Fail Safe Configuration, FailSafe Fall-Back, and Sustained or Momentary Outputs  Various Termination Assemblies (TAs) that contain: • Current limiting devices • Fuses • Relay outputs with external power source, fusing, and power distribution • Solid state outputs • Redundant power distribution.

STANDARD DESIGN

The module has a rugged extruded aluminum exterior for physical protection of the circuits. Enclosures specially designed for mounting the FBMs provide various levels of environmental protection, up to harsh environments (Class G3), per ISA Standard S71.04.

VISUAL INDICATORS

Light-emitting diodes (LEDs) incorporated into the front of the module provide visual indication of the module operational status, as well as the discrete states of the individual output points.
