SPECIFICATIONS
Power: 24, 120, or 240 Vac; 50/60 Hz
A separate earth ground is required for any power source.
Power Consumption:
• 8 VA maximum at 60 Hz
• 10 VA maximum at 50 Hz
Operating & Storage Temperature Ambient Rating:
• -40° to 125° F (-40° to 52° C) @ 50 Hz
• -40° to 140° F (-40° to 60° C) @ 60 Hz
Relative Humidity: 5% to 95% non-condensing
Dimensions: Refer to Fig. 1 on page 4.
All T775 controllers are field-mountable in any orientation
to either a panel or wall.
Digital Input (DI):
• 18 Vdc and 3.5 mA (for choosing external contact)
Digital Output (DO) Alarm (T775P only):
• Alternating Current (AC):
— 30 Vac RMS; 1.5 A steady 3 A inrush P.F. 0.45 NC
— 20 Vac RMS; 100 mA minimum load on NO and NC
contacts
• Direct Current (DC): 1 mA at 100 mV DC minimum load
NOTE: In applications requiring a gold contact signal relay,
an external signal relay or additional load resistor
may be needed for the digital output.
Relay Contact Output Ratings (N.O. and N.C.):
• 1/2 hp; 9.8 AFL, 58.8 ALR @ 120 Vac
• 1/2 hp; 4.9 AFL, 29.4 ALR @ 240 Vac
• 125 VA pilot duty @ 120/240 Vac
• 10A @ 24 Vac (resistive)
Modulating Outputs:
• 0-10 Vdc; drive a minimum of 2,000 Ohms
• 2-10 Vdc; drive a minimum of 2,000 Ohms
• 4-20 mA; drive a maximum of 600 Ohms
• Electronic Series 90; requires 340 Ohm resistor (included)
across terminals R and W
• Floating
Sensed Temperature Limits (displayed):
• Minimum -60° F (-51° C)
• Maximum 270° F (132° C)
High Setpoint Limit: An irreversible high limit setpoint can be
configured to meet local code requirements.
Sensed Temperature Accuracy:
• T775: 1° F/C @ ambient room temperature of 77° F (25° C)
• 50021579-001 and T775-SENS-WR: ±0.42° from -22° to
248° F (+/-.24° from -30° to 120° C)
Setpoint Range: -40° to 248° F (-40° to 120° C)
Time Clock: Two settable time periods per day are standard
on all models.
Volatile Memory: The date and time settings are retained for
24 hours after a power outage. After a power loss of more
than 24 hours, the date and time settings may need to be
reentered. All other settings are stored permanently.
Approvals: UL 60730-1 standard, CuL, CE, C-tick

Humidity Sensors (T775U only)
The controller accepts 0-10 Vdc or 4-20 mA input with a range
of 0-100%
H7625, H7635, and H7655 models (available in 2, 3, and 5%
RH accuracy) can be used.
Low Differential Pressure Sensors (T775U only)
P7640A pressure transducer models with selectable pressure
ranges can be used.
The controller accepts pressure sensors with a signal output
of 0-10 Vdc or 4-20 mA for any output range within the
following ranges (the minimum and maximum for the sensor
output range can be adjusted within the following limits):
• -500 to 500 PSI
• -30.0 to 30.0 inches w.c.
• -3,000 to 3,000 Pa
• -3,000 to 3,000 kPa
Universal Sensors (T775U only)
The controller accepts 0-10 Vdc or 4-20 mA input for
temperature, pressure, humidity, etc. C7232 and C7632 CO
2
sensors are also compatible but output is displayed in %
instead of ppms. (A conversion graph is included in the T775U
