Product Description

Honeywell MCT202 Handheld Configurator Field Communicator

The United Electric J402 S126B Smart Pressure Control Switch (Model 16310-1) is a high-performance, programmable solution designed for precise pressure monitoring and control in industrial environments. Engineered to meet the demands of vacuum systems, HVAC, and process control applications, this switch combines advanced digital technology with robust mechanical reliability. Its ability to handle pressures from -100 kPa (vacuum) to 0 kPa (atmospheric) makes it ideal for detecting low-pressure thresholds in gas, liquid, or air systems where accuracy and safety are paramount.

The J402 S126B features a ±0.5% full-scale accuracy with user-adjustable set points, ensuring reliable operation across a wide range of conditions. The device's SPDT relay output supports switching voltages up to 24 VDC at 1 A, enabling seamless integration with control systems for alarms, pumps, or valves. A backlit LCD display provides real-time pressure readings in multiple units (kPa, psi, bar, inH2O), while intuitive navigation via a digital keypad simplifies on-site configuration. For advanced connectivity, the switch supports HART® protocol, allowing remote diagnostics and integration with distributed control systems (DCS) or asset management software.

Built for durability, the J402 S126B boasts a IP66/NEMA 4X-rated aluminum alloy enclosure that resists dust, water, and corrosion, even in harsh industrial conditions. Its -40°C to +70°C (-40°F to 158°F) operating temperature range ensures stability in extreme environments, from outdoor HVAC systems to chemical processing plants. The switch's 1/4" NPT female process connection (available in stainless steel or brass) and 316 SS diaphragm provide compatibility with aggressive media, while overpressure protection up to 300 kPa (43.5 psia) safeguards against unexpected surges.

Certified for global compliance, the J402 S126B meets CE, UL, FM, RoHS, and CSA standards, with optional IECEx Zone 1/2 approval for use in hazardous locations such as oil & gas facilities or petrochemical plants. Additional smart features include self-diagnostics, adjustable damping to filter rapid pressure fluctuations, and an optional 4–20 mA analog output for continuous process monitoring alongside switching functionality.
