There are input
modules for almost
any input signal.
Input and Output
pins vary for
different modules.
Smart Modules
incorporate their own
A / D converters and
communicate digitally
with the meter.
See section on
I-Series Input Modules
for connection details.

Pinout Diagram
The Rear View of the Meter diagram shows the meter with the
relay configuration: dual 9 Amp Form C and dual 4 Amp Form
A relays� An analog output module is also shown as installed�
The CL-B101D40-TCRTD uses plug-in type screw terminal con-
nectors for all input and output connections� The power supply
connections (pins 14 and 15) have a unique plug and socket out-
line to prevent cross connection� The main board and input signal
conditioner use right-angled connectors as standard� The output
module uses straight-thru connectors as standard�
WARNING
:
AC and DC input signals and power supply
voltages can be hazardous. Do Not connect live wires to
screw terminal plugs, and do not insert, remove or handle
screw terminal plugs with live wires connected.
Standard plug-in screw terminal connectors provided by Texmate:

Input Signal – Pins 1 to 6
Pins 1 to 6 are reserved for the input signal conditioner�
See the data sheet for the selected input signal conditioner�
Pins 8 to 11 – Rear Panel Function Pins
Pins 8 to 11
provide functions that can be implemented
with an external switch. Their pin definitions are:
Pin 11 DIM.
By connecting the display dim (DIM) pin to
the COMMON pin, the display brightness setting
is halved�
Pin 10 COMMON.
To activate the LOCK or DIM
functions from the rear of the meter, the
respective pins have to be connected to the
COMMON pin� This pin is connected to the
internal power supply ground�
Pin 9 No function
Pin 8 LOCK.
By connecting the LOCK pin to the
COMMON pin, the meter's programmed
parameters can be viewed but not changed�
