Frequently Asked Questions - ADAM-3014 Advantech

What type of RTD sensors are supported by the ADAM-3014?

The ADAM-3014 supports Pt100 (α=0.00385) and Ni100 (α=0.00618) RTD sensors in 2-, 3-, or 4-wire configurations. The input type is selected via DIP switches.

How do I configure the input range and sensor type?

Configuration is done using the onboard DIP switches. Refer to the manual for the specific switch positions for Pt100, Ni100, or custom ranges. Jumper settings also allow wire configuration (2/3/4-wire).

What is the isolation voltage of the ADAM-3014?

The module provides 3000 VDC isolation between input, output, and power supply, ensuring reliable operation in noisy industrial environments.

What power supply is required for the ADAM-3014?

The module operates on a DC power supply from 10 to 30 VDC. Typical consumption is less than 1.2 W. Use a regulated supply with adequate current rating (min 200 mA).

Can the ADAM-3014 be used with other communication protocols besides RS-485?

The ADAM-3014 features an RS-485 interface with Modbus RTU protocol. It cannot be directly used with other protocols without an external converter.

How do I connect the ADAM-3014 to a PLC or PC?

Connect the RS-485 A/B terminals to your PLC/PC using a twisted-pair cable. Ensure proper termination (120 Ω) at both ends if needed. Use a USB-to-RS485 converter for PC connection with Modbus software.

What is the maximum cable length for RTD sensors?

For accurate readings, keep RTD sensor cable lengths below 100 meters for 3-wire and 4-wire connections. Longer runs may introduce errors due to lead resistance.

How do I troubleshoot if the module is not responding on the network?

Check the following: 1) Power supply (10-30 VDC). 2) RS-485 wiring (A/B swapped?). 3) Baud rate and parity settings match the master. 4) Modbus address not conflicting. 5) Termination resistors. Use a multimeter to verify power and connection.

Is the ADAM-3014 compatible with 2-wire RTD sensors?

Yes, the module supports 2-wire, 3-wire, and 4-wire RTD connections. For 2-wire, accuracy may be reduced due to lead resistance; use 3- or 4-wire for best precision.

What is the update rate for each channel?

The module updates all four channels at a typical rate of 10 Hz (100 ms per channel). Baud rate can affect overall throughput; default is 9600 bps.

Introduction

The ADAM-3014 is one of the most cost-effective, field-configurable, isolation-based signal conditioners available for protecting processed signals from harmful effects of ground loop, motor noise, and other electrical interference.

The ADAM-3014 features a new optical isolation technique to provide 1000 V _DC isolation with low power consumption and extreme accuracy and stability within a wide range of operating environments. ADAM-3014 typically has a 150 ppm temperature drift and up to 2.4 kHz input bandwidth using only 0.85 W (voltage output) of power. The ADAM-3014 offers superior performance at the lowest price of any signal conditioner or in-house design. A wide variety of input and output ranges can be configured to scale and transmit, therefore spare parts inventory can be reduced and the optimal system flexibility can be achieved.

The ADAM-3014 features three-way isolation. The power supply that drives the module's input circuitry and output circuitry is internally isolated, enabling ADAM-3014 to offer true channel-to-channel isolation.

ADAM-3014's input bandwidth is typically 2.4 kHz. The ADAM-3014 is powered by a single +24 V _DC input. Power can be easily connected from the adjacent modules, making the wiring simple to maintain. The ADAM-3014 can be mounted on a DIN rail and operate in environments with high humidity and wide temperature variation.

Figure 1 shows the terminal wiring of ADAM-3014. Positive power terminals 9 and 7 are internally connected, as are negative terminals 12 and 10. Power can be connected through the adjacent modules, making wiring much easier. ADAM-3014 uses single +24 VDC. Tables 1 and 2 below show the switch positions to configure input and output range. The I/O configuration switches are located inside the module. To reach the switches, you need to remove the DIN-rail bracket by sliding it down.

Calibration for input/output

1. Disconnect power and set the input range (SW2) and output range (SW1) to the desired setting, then apply the power.

**Define the following variables for calibration use.

--Low_cali_input = Min_input + Full Scalar Input * 0.05;
--High_cali_input = Max_input - Full Scalar Input * 0.05;
--Low_cali_output = Min_output + Full Scalar Output * 0.05;
--High_cali_output = Max_output - Full Scalar Output * 0.05; 

1. Input the Low_cali_input signal; read the Low_real_output signal;
   3.Input the High_cali_input signal;read the High_real_output signal;
2. Adjust variable resistor of SPAN and repeat step 2 & 3 to meet the following condition

(High_cali_output - Low_cali_output) = (Low_real_output - High_real_output)----eq1

1. Adjust variable resistor of ZERO and repeat step 2 & 3 to meet the following condition

Low_real_output = Low_cali_output----eq2

High_real_output = High_cali_output----eq3

1. If eq2, eq3 fail to meet your requirement, repeat steps 4,5 until success in step 5
