Overview
The CT15 is an easy to use controller with sophisticated PID
control. It can also be a single or 2-stage alarm (using alarm
feature plus control relay) to monitor motors and generators
for overheating.
• RTD or thermocouple input
• Control modes: Self-Tune, pre-set or programmable PID, or
On/Off
• Bright red LED display
• Ramp to setpoint
• Digital sensor input correction
• Digital input filter adjustable for noisy or jittery processes
• Four security levels
• Setpoint limits
• Non-volatile memory needs no battery backup
• Input fault timer
• Alarms at one or two temperatures
• Alarm Relay option is programmable for high, low, absolute, or
deviation. Relay can be reset manually or automatically and
controls a single electromechanical relay with voltage-free
contacts
Specifications
Selectable inputs:
RTD: 2 or 3-wire, Minco types PD or PE (100 Ω EN60751 platinum).
Thermocouple: Type J (factory default), K, T (selectable).
Input impedance:
Thermocouple: 3 megohms minimum.
RTD current: 200
μ A maximum.
Sensor break or short protection: De-energizes control out-
puts to protect system.
Loop break protection: Error message is initiated and output is
turned off in case of shorted sensor or open heater circuit.
Break time adjustable from OFF to 99 minutes.
Cycle rate:1 to 80 seconds.
Setpoint range: Selectable from -212 to 1371°C (-350 to
2500°F), input dependent.
Display: One 4 digit, 7 segment, 0.3" high LED. Display shows
the measured temperature unless a control key is pressed, then
it will display the item value.
Control action: Reverse (usually heating) or Direct (usually
cooling), selectable.
Ramp/Soak: One ramp, 0 to 100 hours.
