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.

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�
