OUTPUT MODULES

Units equipped with RS485 option must have the Dual Alarm or Cooling w/

alarm options fitted with the same type of output modules. The controller’s

main output (OP1) can be fitted with any output module. Output modules are

shipped separately and must be installed by the user.

TYPICAL CONNECTIONS

Relay:

Type: Form -C (Form-A with RS485 option only)

Rating: 5 Amps @ 120/240 VAC or 28 VDC (resistive load), 1/8 HP @ 120

VAC (inductive).

Life Expectancy:100,000 cycles at maximum load rating.

(Decreasing load and/or increasing cycle time, increases life expectancy).

Drive: 45 mA max.

Triac:

Type: Isolated, Zero Crossing Detection.

Rating:

Voltage: 120/240 VAC.

Max. Load Current: 1 Amp @ 35°C

0.75 Amp @ 50°C

Min. Load Current: 10 mA

Off State Leakage Current: 7 mA max. @ 60 Hz

Operating Frequency: 20 to 500 Hz.

Protection: Internal Transient Snubber, Fused.

APPLICATION

TSC GLASS TEMPERING APPLICATION

A manufacturer of glass items needs to

anneal (temper) their products to reduce the

brittleness of the glass structure. The tempering

process requires the glass to be heated and

subsequently cooled at a controlled rate to

change the structure of the glass. Different

tempering profiles are required for different

types of glass products.

A TSC is employed to control the

temperature profile of the annealing oven.

Four different temperature profiles are stored in

the controller. The 4 to 20 mA analog output

option is utilized to cool the annealing oven

during the cool down ramp phases. An event

output is used to quickly cool the oven at the

end of the batch run (alarm 1). Alarm 2 is used

to signal the operator whenever the temperature

is outside the prescribed program profile.

Note: Units equipped with the RS485 option

have different terminal designators. See

“Output Variations with or without the

RS485 Option”.

The programming for this profile is as follows:

Ramp from ambient temp. during heat phase at

5.0°/min.

“P1L1”

300

Target setpoint level 300°

“P1H1”

40.0

Heat at 300° for 40.0 minutes

“P1r2”

3.0

Ramp down 3.0°/min. during cooling phase

“P1L2”

150

Target Setpoint is 150°

“P1H2”

0.0

Do not hold at 150° (used as “phantom” hold time

for triggering event output for auxiliary cooling)

“P1r3”

-0.1

End Program

“P1 1”

1F2F

Turn off output 1 (output 2 is alarm)

“P1 2”

1F2F

Keep off output 1

“P1 3”

1F2F

Keep off output 1

“P1 4”

1N2F

Turn on output 1 for Auxiliary Exhaust Fan
