Input Power Class 2; 24 Vac/dc nominal, 30 Vac max.; 150 mA max. Control Input Class 2; 4 to 20mA/0-5 V/0-10 Vdc; jumper-selectable Input Impedance 4 to 20 mA, 250 Ω; 0-5 V/0-10 Vdc, 10 kΩ Manual Override Jumper-selectable mode, digital pushbutton adjust Alarm Contact 100 mA@30 Vac/dc (pressure loss, manual mode, jumper selectable) Accuracy 1% FS; combined linearity, hysteresis, repeatability Compensated Temp Range -4 to 65 °C (25 to 140 °F) Temperature Coefficient ±0.05%/°C Operating Environment 10 to 90% RH non-condensing Air Capacity 523 in3/min @ 45 psi (8570 cm3/min @ 310.3 kPa); 333 in3/min @ 20 psi (5456 cm3/min @ 137.9 kPa) Supply Pressure 45 psig max. Control Range 0 to 20 psig or 3 to 15 psig, jumper-selectable Pressure Differential 0.1 psig (supply to branch) Pressure Indication Electronic, 3-1/2 digit LCD EP Series transducers are sold as an open device. Observe handling precautions for static sensitive devices to avoid damage to the circuitry which would not be covered under the factory warranty. **The CE mark applies to models with cover only. *For shorter tubing runs use AA45 Pneumatic Capacitor EMC Conformance - CE option: Low voltage directive 2014/35/EU; EMC directive 2014/30/EU. EMC Special Note: Connect this product to a DC distribution network or an AC/DC power adaptor with proper surge protection (EN 61000-6-1 specification requirements). The EP2 Series electropneumatic pressure transducer uses micro- controlled poppet valve technology for highly accurate pressure sensing in multiple applications. The poppet valves consume no air, eliminating unnecessary air losses in the system and allowing for stable and reliable operation. The EP2 comes installed on standard SnapTrack, and an optional dust cover is available to protect from the environment. An LCD display and LED indicators make it easy to read system status at a glance.
