7.2 Electronics
Power
• Supply Voltage: 7 to 28 VDC (loop-powered, customer supplied)
• Output: 4 to 20 mA
• Output Resolution: 0.01 mA
• Max. Loop Resistance: R = 50 Ω × (PSV–7),
where PSV = Power Supply Voltage
Example: For a PSV = 24 VDC, R = 50 Ω × (24–7) = 850 Ω
• Cable: 2 m, standard (consult factory for custom lengths)
