TCS Basys Controls TZ1004 Transmitter

The TCS Basys Controls TZ1004 is a professional-grade RH transmitter with display engineered for high-accuracy relative humidity monitoring in commercial HVAC systems. This wall-mount device provides technicians with a precise 4-20 mA output signal, ensuring seamless integration with building automation systems (BAS) and environmental controllers. Designed for durability and stability, the TZ1004 features a rugged polymer resistive sensor and a clear digital humidity display for real-time localized monitoring, critical for maintaining strict climate requirements in standard room environments.

Built to handle HVAC relative humidity sensing with reliable precision, this transmitter operates on a linear 4 to 20 mA DC 2-wire loop. The unit supports a wide supply voltage range from 8 to 35 VDC, offering polarity protection and significant resistance to radio frequency interference. With an operating temperature range of 32 to 122°F and a high-accuracy humidity range of 0 to 100% RH (non-condensing), the TCS Basys Controls TZ1004 is the go-to solution for contractors requiring a dependable humidity sensor transmitter that stands up to the demands of modern air handling and ventilation control.

Key Benefits

• High Precision Sensing: Utilizes a bulk polymer resistive sensor for superior long-term stability and accurate RH measurement.
• Integrated Local Display: Features a digital display for instant, on-site verified humidity readings without needing a multimeter.
• Standard 4-20 mA Loop: Simplifies installation with a low voltage 2-wire output compatible with most major building controllers.
• Robust EMI/RFI Rejection: Engineered to minimize signal drift caused by electromagnetic and radio frequency interference in mechanical rooms.
• Contractor-Friendly Design: Designed for standard vertical wall mounting on drywall, block, or 2" x 4" conduit boxes.

Common Questions

How do I wire the TZ1004 for a 4-20 mA signal?
The unit is a loop-powered, 2-wire transmitter. Connect the positive supply (8-35 VDC) to the designated terminal and the signal return to the controller's analog input. Ensure 18 AWG twisted, shielded pair wiring is used to maintain signal integrity.

Can the TZ1004 be used in high-temp environments?
The transmitter is rated for an operating temperature of 32 to 122°F (0 to 50°C). For applications exceeding these limits, such as high-temperature exhaust or boiler rooms, verify that the electronics housing remains within the specified ambient range.

Is the sensor replaceable or field-serviceable?
The TZ1004 is designed for stability with a resistive sensor. While the sensor is built for longevity, its performance can be verified via the local display. If calibration drift occurs, use the non-interacting zero and span adjustments to bring the unit back within technical specifications.
