ABB 07 EA 60 R1 (GJV3074350R1) Analog Input Module Installation & Commissioning Guide

1. Product Overview

The ABB 07 EA 60 R1 (Article No. GJV3074350R1) is a KNX analog input module for reading 0–10V DC signals from sensors (temperature, humidity, pressure, light, etc.). It converts analog values to KNX telegrams for building automation.

Key Features

  • 6 analog inputs (0–10V DC)

  • KNX TP1 communication

  • Configurable measurement ranges & functions

  • DIN-rail mounting

  • Suitable for: Temperature sensors, humidity sensors, light sensors, pressure sensors, potentiometers


2. Safety Instructions

⚠️ Warnings:

  • Disconnect KNX bus and analog input power before installation.

  • Ensure external analog sensors are SELV (Safety Extra Low Voltage) compliant.

  • Do not exceed 11V DC on analog inputs to avoid damage.

  • Use appropriate cable types and follow local electrical regulations.

  • Only qualified electricians/installers should perform installation.


3. Installation Steps

3.1. Mounting

  1. Mounting position: DIN rail (35 mm) in electrical cabinet.

  2. Clearance: ≥ 10 mm above/below for heat dissipation.

  3. Environment:

    • Temperature: -5°C to +45°C

    • Humidity: ≤ 93% (non-condensing)

  4. Snap module onto DIN rail until it clicks into place.

3.2. Wiring Connections

Terminal Function Wire Type Notes
A1, A2 KNX bus KNX cable (red/black) Polarity protected
1, 2 Analog Input 1 (AIN1) 2-core shielded (0.5–1.5 mm²) 1: +, 2: GND
3, 4 Analog Input 2 (AIN2) Same as above 3: +, 4: GND
5, 6 AIN3 Same 5: +, 6: GND
7, 8 AIN4 Same 7: +, 8: GND
9, 10 AIN5 Same 9: +, 10: GND
11, 12 AIN6 Same 11: +, 12: GND
13, 14 +24V DC Aux Supply (optional) 0.5–2.5 mm² For sensor power

Wiring Tips:

  • Use shielded cables for analog signals.

  • Ground shield at one end only (sensor side recommended).

  • Keep KNX and analog cables separate to avoid interference.

  • Max cable length: 50 m (for stable 0–10V signal).

3.3. Power Supply

  • KNX bus power: 21–30V DC (standard KNX).

  • Auxiliary 24V DC: Optional for powering connected sensors.

  • Sensor power: Each input can supply ≤ 2 mA if configured as voltage source.


4. ETS Configuration & Programming

4.1. Pre-requisites

  • ETS software (version 5 or higher).

  • ABB device database imported.

  • KNX programming interface connected.

4.2. Parameter Settings (Key Functions)

Analog Input Configuration (per channel):

  1. Measurement type:

    • Voltage (0–10V)

    • Resistance (potentiometer)

    • Temperature sensor (NTC/PTC)

    • Custom curve (via ETS table)

  2. Scaling:

    • Map 0–10V input to physical values (e.g., 0V = 0°C, 10V = 50°C).

    • Set send threshold to reduce bus traffic (e.g., send only if change > 0.5V).

  3. Filtering:

    • Adjust averaging time (1–60 seconds) for stable readings.

  4. Function modes:

    • Standard mode: Send value cyclically/on change.

    • Window mode: Send only if value enters/leaves defined range.

    • Comparator mode: Activate binary output if threshold exceeded.

4.3. Group Address Assignment

  • Assign group addresses for:

    • Measured value (2-byte float/integer)

    • Status/error flags

    • Configuration commands (e.g., recalibration)


5. Commissioning & Testing

5.1. Step-by-Step Verification

Step Procedure Expected Result
1 Apply KNX bus power Green LED on (steady)
2 Connect sensor to AIN1 Voltage reading in ETS monitor
3 Short AIN+ to GND Reading ≈ 0V in ETS
4 Apply known voltage (e.g., 5V) ETS shows corresponding scaled value
5 Test each input channel All channels respond correctly
6 Verify group communication KNX objects send/receive as configured

5.2. Calibration

  1. Use precise voltage source (multimeter verified).

  2. In ETS, set offset/gain correction if readings deviate.

  3. For sensors: apply known physical condition (e.g., ice bath for 0°C) and calibrate.

5.3. Functional Tests

  • Cyclic sending: Confirm telegrams at set intervals.

  • Threshold triggers: Change input past setpoint → telegram sent.

  • Integration test: Verify linked actuators respond correctly (e.g., valve opens when temperature rises).


6. Troubleshooting Guide

Symptom Possible Cause Solution
No LED lit No KNX bus power Check bus voltage & polarity
Red LED flashing KNX communication error Check bus termination, wiring
Input reading 0V Sensor not powered Check auxiliary 24V, sensor wiring
Unstable readings Electrical interference Use shielded cables, separate from AC lines
Value stuck at max Sensor short circuit Check sensor resistance/wiring
ETS cannot program Incorrect physical address Reset to factory defaults (see manual)

Factory Reset:
Press and hold programming button (5 sec) until LED flashes red/green.
