Field Termination Modules (FTMs)
8.1—Introduction
Field Termination Modules (FTM) are used to connect field wiring to the front of
the MicroNet control’s I/O Modules. They connect to the subminiature D-type
connectors on the front of the I/O modules and provide cage-clamp terminal
connection points for field wiring. They also provide shield termination and EMI
protection. All FTMs can be mounted on 35 mm DIN Rails and take the place of
interposing terminal blocks to field wiring.
The cage-clamp terminals on the FTMs and relay modules accept a maximum of
one #12 AWG wire or two #18 AWG wires. Field wiring hookup is performed by
stripping the wire back 0.312 inches (8 mm), inserting into the cage clamp and
tightening the screw.
8.2—Analog I/O FTMs
8.2.1—24/8 Analog FTM
The 24/8 Analog FTM is used with the 24/8 Analog Modules (see Chapter 7
MicroNet module information and Appendix A for FTM part number). One
MicroNet High Density Analog/Discrete cable is use to connect the FTM with the
24/8 Analog Module (see Appendix A for part numbers). There are 24
Vdc connections available for sourcing 4-20 mA inputs. Each connection is
protected with a 0.1 A fuse.
