3 Input Voltage/Current Transmitter (3IVCT)

This product was designed to provide a cost-effective way to provide for three individually isolated, analogue inputs up to 600 V and 15 A with true RMS conversion. The isolated analogue outputs share a common 0V as they are designed to go into a PLC or some other non-isolated analogue input device.

• Uses three powerful microprocessors to do true RMS to DC conversion and digital signal isolation.
• Flexibility, reliability and accuracy at an economical price in an industrial package for safe operation up to 600 VAC.
• Voltage measurement can be DC or AC (true RMS) up to 600 V and current inputs DC or AC (true RMS) up to 15 A. A millivolt input option can be used for external current shunts.
• Accuracy better than 0.5% with isolated current or voltage outputs using 12 or 24 VDC nominal supplies.
• Each input and each output can be configured differently and they need not all be the same.

Inputs:

• Three separate, isolated inputs, voltage and current which can be either AC or DC.
• 0 to 600 V in several ranges: 0-600, 0-400, 0-250, 0-150 V (link configurable).
• 0 to 15 A in four ranges: 0-1, 0-5 A (link configurable) and 0-10, 0-15 A (factory configurable by changing shunt resistors).
• True RMS AC conversion.
• Input frequency measurement response range 0 to 500 Hz.
• 12 bit input conversion for AC, 16 bit input conversion for DC.
• Dedicated processor for each input to do true RMS to DC conversion, signal conditioning and digital signal isolation.
• Isolation input to output and input to auxiliary power supply >2 kV.

Outputs:

• 3 outputs sharing a common 0 V – primarily designed for PLC or other controller type inputs.
• 0-20 mA, 4-20 mA, 0-10 V, 0-5 V and ±10 V.
• Output response time approximately 1 second or less.
• 12 bit output conversion.

Aux Power:

• 12 VDC +10%, -5% at approximately 500 mA maximum
• 24 VDC +10%, -5% at approximately 300 mA maximum 
• or optional wide range input 9 to 36 VDC.

Connection:

• Bottom entry cable glands for high voltage inputs suitable for cable diameters 4 to 10 mm with PCB mounted push-in power terminals.
• Output and power cable glands for cable diameters 2.5 to 6.5 mm at the top of the enclosure.

Operation:

• Test sheet supplied for each unit after burn-in with calibration and accuracy information shown for each input.
• Operating temperature -10°C to 60°C.
• 24 hour operational burn-in.

Enclosure:

• IP66 ABS enclosure, chassis mounting, dimensions (including cable glands) 160 x 170 x 90 mm (width x height x depth).
• Mounting footprint drill centres 100 x 140 mm.
• Packaged size: 260 x 195 x 115 mm (L x W x H) – weight 0.6 kg.
