NTCL01 Termination Unit (Introduction)

NTCL01 Termination Unit (Introduction)
SECTION 1 - INTRODUCTION
INTRODUCTION
The Communication Termination Unit (NTCL01) provides a termination point for a Network Interface Slave Module (INNIS01)
or a Loop Interface Module (INLIM03). The TCL gives the option
of using twinaxial or coaxial cable to connect the NIS to the
INFI-NET communication network or the LIM to Plant Loop.
Jumper settings on the TCL select the type communication
cable. Figure 1-1 shows an example of the NTCL01 within a
PCU on the INFI-NET communication network.
INTENDED USER
Technicians should read the manual before installing and
operating the TCL. Do not put the TCL into operation until you
read and understand this instruction.

HARDWARE DESCRIPTION
The TCL attaches to a Field Termination Panel (NFTP01), inside
the INFI 90® cabinet, with two mounting screws and one
ground screw. It is a printed circuit board that consists of:
•
•
•
•
•
Terminal strips
BNC connectors
Electronic components
Jumpers
Fuse
FEATURES
The NTCL01 provides connectors for both twinaxial cable and
coaxial cable. Jumpers on the circuit board set the impedance
to match the communication cable. The +24 VDC supplied to
the board is fused, protecting the electronic circuitry on board.
INSTRUCTION CONTENT
This manual has five sections and two appendices.
Introduction
