Schematic Circuitry & Connection Diagram

The device includes an input section with a low drift amplifier, an isolation barrier, and an output driver. Power is supplied to terminals 7 (U+) and 8 (V-). Input signals connect to terminals 3 (+) and 4 (-), while output signals connect to terminals 5 (+) and 6 (-). An input shunt resistor is incorporated for current input.

Points of Caution

• Conformity with EC Directives:
  • Equipment must be mounted inside a panel.
  • Insert a noise filter for power source, input, and output (e.g., COSEL NAC-06-472, TDK ZCAT 3035-1330).
  • Installation environments may affect protection level; review CE requirements and employ additional protective measures.
• Power Input Rating & Operational Range:
  • Confirm power input rating marked on the product.
  • 85-264V AC rating: 85-264V, 47-66 Hz, approx. 2-3VA.
  • 24V DC rating: 24V ±10%, approx. 2W.
• General Precautions:
  • Turn off power supply and input signal before removing or mounting the unit.
• Environment:
  • Indoor use only.
  • Install inside proper housing with sufficient ventilation if heavy dust or metal particles are present.
  • Avoid continuous vibration or physical impact.
  • Environmental temperature: -5 to +55°C (23 to 131°F) with relative humidity 0 to 90% RH.
• Wiring:
  • Do not install cables (power supply, input, output) close to noise sources (relay drive cable, high frequency line, etc.).
  • Do not bind these cables with noisy ones or install them in the same duct.
  • Install lightning surge protectors for wires connected to remote locations.
  • For 24V DC power supply line, choose a surge protector with a maximum surge voltage 40V or less between lines (e.g., M-System MDP-D24).
• Warm-up: The unit is designed to function as soon as power is supplied, but a warm-up of 20 minutes is required for satisfying complete performance.

Installation Procedure

Set the unit so that its DIN rail adapter is at the bottom.

Mounting the Unit on a DIN Rail:

1. Hang the upper hook at the rear side of the unit on the DIN rail.
2. Push in the lower part while keeping pressing the unit to the DIN rail.

Removing the Unit:

1. Push down the DIN rail adapter using a minus screwdriver.
2. Pull out the lower part of the unit.
3. Remove the upper part from the DIN rail.

Checking

1. Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2. Power input voltage: Check voltage across terminals 7-8 with a multimeter.
3. Input: Check that the input signal is within 0-100% of the full-scale.
4. Output: Check that the load resistance meets the described specifications.

Adjustment Procedure

The unit is factory calibrated to meet ordered specifications, so calibration is usually not needed. For matching the signal to a receiving instrument or for regular calibration, adjust the output as explained below.

How to Calibrate the Output Signal: Use a signal source and measuring instruments of sufficient accuracy. Turn on the power supply and warm up for more than 20 minutes.

1. ZERO: Apply 0% input and adjust output to 0%.
2. SPAN: Apply 100% input and adjust output to 100%.
3. Check ZERO adjustment again with 0% input.
4. If the ZERO value is changed, repeat steps 1-3.

Maintenance

Calibration: Warm up the unit for at least 20 minutes. Apply 0%, 25%, 50%, 75%, and 100% input signal. Check that the output signal for the respective input signal remains within the accuracy described in the data sheet. If the output is out of tolerance, recalibrate the unit according to the "ADJUSTMENT PROCEDURE" explained above.
