Specifications
Selectable inputs:
RTD: 2 or 3-wire, Minco types
PD or PE (100 Ω EN60751 platinum),
PA (100 Ω NIST platinum),
PF (1000 Ω EN60751 platinum), or
NA (120 Ω Nickel).
Thermocouple: Type J (factory default), K, T, L, E, R, S, B, C, or N.
DC current: 0-20 mA or 4-20 mA (use with Temptran™ transmitters).
DC voltage: 0-10 or 2-10 VDC, -10 to 10 mVDC, scalable.
Input impedance:
Voltage: 5000 Ω.
Thermocouple: 3 megohms minimum.
Current: 10 Ω.
RTD current: 200
μ A.
Sensor break or short protection:
Selectable output: disabled, average output before fault,
or preprogrammed output.
Adjustable delay: 0.0 to 540.0 minutes.
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 9999 seconds.
Cycle rate: 1 to 80 seconds.
Setpoint range: Selectable from -212 to 2320°C (-350 to
4208°F), input dependent.
Displays: Two, 4 digit, 7 segment, 0.3" high LEDs. Process Value
red, Setpoint Value green. °C or °F.
Control action: Reverse (usually heating) or Direct (usually
cooling), selectable.
Ramp/soak: (CT16A3 only) 16 separate ramp and soak times
are adjustable in minutes or seconds from 0 to 9999. When the
program has ended, you may choose to repeat, hold, revert to
local setpoint, or turn the outputs off.
Accuracy: ±0.25% of span ±1 count.
Resolution: 1° or 0.1°, selectable.
Line voltage stability: ±0.05% over supply voltage range.
Temperature stability: 4
μ V/°C (2.3 μ V/°F) typical, 8 μ V/°C
(4.5
μ V/°F) max. (100 ppm/°C typical, 200 ppm/°C max.).
Isolation:
Relay and SSR: 1500 VAC to all other inputs and outputs.
SP1 and SP2 current and voltage: 500 VAC to all other inputs
and outputs, but not isolated from each other.
Process output (options 934, 936): 500 VAC to all other inputs
and outputs.
Supply voltage: 100 to 240 VAC nom., +10/-15%, 50 to 400 Hz,
single phase; 132 to 240 VDC, nom., +10/-20%. 5 VA maximum.
12 & 24 volt AC/DC optional.
Note: Do not confuse controller power with heater power. The
controller does not supply power to the heater, but only acts as
a switch. For example, the controller could be powered by
115 VAC, but controlling 12 VDC to the heater.
Operating temperature range: -10 to 55°C (14 to 131°F).
Memory backup: Non-volatile memory (no batteries required).
Control output ratings:
AC SSR (SPST): 2.0 A combined outputs
A & B @ 240 VAC @ 25°C (77°F);
derates to 1.0 A @ 55°C (130°F).
An SSR is recommended for longer life than a
mechanical relay.
Mechanical relay, SPST Form A (Normally Open) or Form B
(Normally Closed):
3 A resistive, 1.5 A inductive @ 240 VAC;
pilot duty: 240 VAC; 2 A @ 120 VAC or 1 A @ 240 VAC.
Switched voltage (isolated): 15 VDC @ 20 mA.
Proportional current (isolated): 0 to 20 mA, 600 Ω max.
DC SSR: 1.75 A @ 32 VDC max.
Alarm relay, SPST Form A (Normally Open):
3 A @ 240 VAC resistive;
1/10 HP @ 120 VAC.
