Loop Powered Process Signal Isolator

Applications:

• Elimination of the effects of ground loops from distributed process signals.
• The protection of signals against common mode interferences such as motors, contactors and power line surges.
• The outputs can drive loads of up to 500 Ω which is sufficient to drive a measurement loop of several kilometres.
• Individual channel isolation and the elimination of common mode offsets for non-isolated computer and PLC inputs.

Specifications:

• Loop powered - no auxiliary supply needed.
• Wide input range 0 to 50 mA.
• Low voltage drop - less than 8.5 V at 250 Ω load at 20 mA.
• Good linearity - better than ±0.5 % at 250 Ω load.
• Input signals limiting at 33 V with reverse input protection.
• Output signal range 0 to 50 mA.
• Output load 500 Ω maximum.
• Low cost process signal isolation.
• Eliminate problems due to common measurement loop connections.
• No external power supply required.
• 500 VAC isolation.
• Frequency response approximately 1 Hz.
• Isolation between input, output >500 VAC.
• Operating temperature -10°C to 60°C.
• 24 hour operational burn-in.
• Calibration sheet provided for each unit manufactured.
• DIN rail mounting.
• Screw terminal connections.
• Dimensions 25 x 80 x 85 mm (W x H x D).
