TABLE 2-2.  TB1 INPUT/OUTPUT TERMINAL ASSIGNMENTS

TERMINAL NO.

NAME

DESCRIPTION OR FUNCTION

1

Control

With a jumper between these terminals and the battery connected, the TBC Con-
trol Board will remain ON even if the AC Circuit Breaker is OFF. With the jumper 
removed the Control Board will go OFF if the AC Circuit Breaker is OFF. 

2

ON/OFF

3

Meter (+)

This terminal provides an outside contact point from the positive side of the LCD 
voltmeter for remote monitoring of the output voltage.

4

+S 

(Sense)

This terminal is the positive Remote Sensing terminal for the TBC output voltage.

5

+M 

(Monitor)

This terminal is connected to the positive output terminal of the TBC Battery Char-
ger and is used for Local Sensing. 

6

–M

(Monitor)

This terminal is connected to the negative output terminal of the TBC Battery 
Charger and is used for Local Sensing. 

7

–S

(Sense)

This terminal is the negative Remote Sensing terminal for the TBC output voltage. 

8

Meter (–)

This terminal provides an outside contact point from the negative side of the LCD 
voltmeter for remote monitoring of the output voltage. 

9

CB

(Current Balance)

This terminal is used when two or three TBC units (except for the TBC 12-20M, 
which doesn't require Current Balance) are connected in parallel (consult the fac-
tory for details). 

10

Common

This terminal is logic ground.

NAME

DESCRIPTION OR FUNCTION

1

+RC

(Remote Control)

Remote Control ON/OFF Input Command. An open (logic high) between the +RC 
and -RC terminals will turn OFF the TBC. A short circuit (or logic low) between 
these two terminals will return the TBC to operation. Logic high is between 2.4V 
and 24V d-c; logic low is between 0V and 0.4V d-c. When high, this terminal can 
sink 1.0 rnA maximum; when low this terminal can source 1.6rnA maximum. 

2

–RC

(Remote Control)

3

Power On

Power On Output Flag. A logic high at this terminal (with respect to Common) 
indicates that AC input power is ON. A logic low indicates that AC input power is 
OFF. 

4

Charging Stopped

Charging Stopped Output Flag. A logic low at this terminal (with respect to Com-
mon) indicates that the battery voltage is equal to or greater than the Power Sup-
ply voltage and that the battery has been charged. A logic high indicates that the 
Power Supply voltage is higher than the battery voltage and that the battery is 
being charged

5

Float/Equalize

Float/Equalize Output Flag. A logic high at this terminal indicates that the TBC is 
in the Float (low charging rate) mode. A logic low at this terminal with respect to 
Common indicates that the TBC is in the Equalize (high charging rate) mode. 

6

Start

Start Input Command. A short circuit condition (provided by a computer low signal 
or momentarily closing a switch) at this terminal with respect to Common starts 
the TBC timer and the TBC goes into the Equalize mode. 

7

+5 Volts

+5 Volts d-c

8

Reset

A short circuit condition (provided by a computer low signal or momentarily clos-
ing a switch) at this terminal with respect to Common resets the Equalize Timer 
and the TBC goes back to the Float mode. 

9

50/60Hz

A jumper between this terminal and Common sets up the TBC for 60Hz input 
power operation. With jumper removed the TBC is set for 50Hz input power oper-
ation. 

10

Common

This terminal is logic ground.
