The EWTR 930 is a new series of micro-processor based and fully programmable process controllers with dual output and Neutral Zone (Dead Band).
• Dimensions: front 72x72 mm (2.84x2.84"), depth 102 mm (4.00")
• Mounting: flush panel mount with mounting bracket. Panel cut-out 67x67 mm (2.64x2.64")
• Connections: quick-disconnect screw terminal blocks (2.5 mm2; one wire each terminal only)
• Display: 12.5 mm LED (0.50")
• Outputs: two (2) SPDT relays 8(3)A 250V AC, or two (2) “static” (switched) outputs 0/12 Vdc 40 mA
• Programmable analog output (optional): 4…20 mA or 0…5 V, depending on model
• Auxiliary output: 12 Vdc/60 mA (for transducer power supply, e.g. temperature sensor, etc.; ground goes to terminal 10)
• Inputs (depending on model): PTC / RTD (Ni100, Pt100) / TC (J, K) / 4…20 mA (Ri = 41 -) for EWTR 930, EWHS 28/31 for EWHR 930 and EWPA 007/030 for EWPR 930
• Resolution: 1 °C (°F) or 0.1 °C (°F). The right-most digit can also be set to read-out in 0 or 5 only, or in all 10 digits
• Accuracy: better than 0.5% of full scale
• Power supply (depending on model): 220, 110, 24 Vac, 50/60 Hz; 12 Vac/dc
