Product Overview

The ICC212 belongs to the ICC200 Series. Its product type is a Repeater Power Supply/Isolating Driver. The product classification is Power Supplies. The current price for this item is ¥2,980 RMB. The product gross weight is 0.28 kg.

This ICC212 serves two complete functions in one device. You can use it as a repeater power supply for transmitters. You can also use it as an isolating driver for control signals. The unit provides fully floating, isolated dc power. It energizes conventional 2-wire or 3-wire 4 to 20mA transmitters. The ICC212 then repeats the current in another isolated circuit. It also accepts a 4 to 20mA signal from a controller. This signal drives loads up to 650Ω.

Technical Specifications

Galvanic Isolation

The ICC212 provides three-port galvanic isolation. Isolation exists between the power supply, input, and output. The isolation rating is 1500V dc/ac. This protects your control system from ground loops. It also prevents voltage spikes from damaging sensitive equipment.

Power Supply Requirements

You need a 20 to 35V dc power supply for operation. The power supply terminations sit at the top of the unit. This uniqueMTL placement allows dual-purpose use. One green LED indicates POWER ON status. The voltage available to the transmitter is 20V minimum at 20mA.

Input and Output Signal Range

The normal operating range is 0 to 20mA. For digital communication, the range is 4 to 20mA. The ICC212 supports bi-directional digital signal transmission. This works for smart transmitters with superimposed communication. You can interrogate the transmitter from an operator station. A hand-held configurator also works perfectly.

Load Resistance and Accuracy

For conventional transmitters or driver mode, the maximum load is 650Ω. For smart transmitters, the load range is 220Ω to 650Ω. The voltage drop across the input at terminals 5 and 6 is less than 1V. Transfer accuracy at 25°C is better than 20μA. This includes non-linearity and hysteresis. Temperature drift stays below 1μA/°C.

Response Time and Bandwidth

The response time to reach 90% of span is 80ms. To reach 99.9% of span, the time is 280ms. The digital signal bandwidth ranges from 100Hz to 10kHz. This supports full HART communication capability. The common mode rejection ratio is 150dB typical.

Power Requirements by Mode

When supplying a transmitter, the ICC212 draws 135mA max at 20V. This occurs with a 20mA signal. At 35V with a 20mA signal, it draws 95mA max. In current source input mode, it draws 90mA at 20V. At 35V with a 20mA signal, it draws 65mA.

Environmental Specifications

The ambient operating temperature range is -20°C to +55°C. The storage temperature range is -40°C to +80°C. Humidity tolerance is 5 to 95% RH non-condensing. This makes the ICC212 suitable for most industrial environments.

Mechanical Specifications

Terminals accommodate 2.5mm² conductors. The power supply uses a removable 2-way plug-in connector. This connector sits at the top of the unit. The casing is 25mm wide polyamide material. Mounting is directly onto T-section or G-section DIN-rail. The rail standard is DIN 46277.

HART Compatibility

The ICC212 works with all HART compatible devices. This includes virtually every smart transmitter on the market. Bi-directional digital communication passes through the unit seamlessly. You can configure and interrogate devices without interrupting the analog signal.

Installation Guide

Follow these steps to install your ICC212 correctly.

1. Select Mode: Decide if you need repeater power supply or driver function. The terminal wiring determines the mode.

2. Mount Unit: Clip the ICC212 directly onto T-section or G-section DIN-rail. The 25mm width saves panel space.

3. Connect Power: Use the removable 2-way plug-in connector at the top. Connect 20 to 35V dc to the power terminals.

4. Wire for Repeater Mode: Connect your 2-wire transmitter to the input terminals. The ICC212 provides loop power.

5. Wire for Driver Mode: Connect your controller output to terminals 5 and 6. Connect the load to the output terminals.

6. Verify LED: Check that the green POWER ON LED illuminates. This confirms correct power supply connection.

7. Test Communication: For HART devices, connect your configurator anywhere on the loop. The ICC212 passes digital signals bi-directionally.

Frequently Asked Questions (FAQ)

1. Can the ICC212 work with both 2-wire and 3-wire transmitters?
Yes, the ICC212 powers both 2-wire and 3-wire conventional transmitters. It also supports smart transmitters with HART communication.

2. What is the main difference between repeater and driver mode?
Repeater mode powers a transmitter and repeats its current output. Driver mode accepts a signal from a controller and drives a load up to 650Ω.

3. Does the ICC212 pass HART communication in both directions?
Yes, this unit allows bi-directional digital signal transmission. You can interrogate the transmitter from a control room or a hand-held configurator.

4. What happens if I exceed the maximum load resistance of 650Ω?
The ICC212 cannot drive loads beyond 650Ω in driver mode. For smart transmitters, the load must stay between 220Ω and 650Ω.

5. Can I use this module in a high-vibration environment?
Yes, the ICC212 mounts securely on DIN-rail. The removable power connector and cage-clamp terminals hold wires firmly. The operating temperature range is -20°C to +55°C.
