Data acquisition & logging supplier in South Africa - local stock, expert support

Why local DAQ supply matters for your project

When you design, test or monitor systems, delays in hardware or unclear specs stop progress. As a South African data acquisition and logging supplier with national branches, Communica puts in-stock DAQ modules, standalone loggers and integration accessories within reach - reducing lead times and simplifying procurement for students, technicians and engineering teams.

Practical benefits you’ll see immediately

• Buy now, collect in Samrand or Pretoria CBD to keep schedules on track - check branch hours on our Branches & Trading Hours.
• VAT invoices and account quoting for institutional purchases streamline tender and lab buying.
• Hands-on support: pick compatible sensors, cabling and software bundles from our product categories to get a working test setup fast.

DAQ categories at a glance

Different projects require different architectures - Communica stocks a spectrum from USB/PCIe DAQ modules to battery-powered data loggers and IoT-enabled remote recorders. Browse by application or brand in our collections to match hardware to your workflow.

Specification callouts to prioritise

• Resolution & sample rate - choose resolution (12/16/24-bit) and sample rate based on sensor bandwidth and dynamic range.
• Input type - thermocouple, RTD, voltage, current (shunt or 4-20 mA) affect front-end conditioning and connectors.
• Isolation & grounding - for industrial setups, isolated inputs prevent ground loops.

Quick compatibility checklist

Before you order, confirm sensor output type, expected voltage/current range, and required sample rate. Our online collections make it easy to assemble matched sensor + DAQ bundles without guesswork.

Selection guidance, calculations and real examples

Match the following simple calculation to your requirement: if you need to capture a 200 Hz signal with at least 10 samples per cycle, required sample rate = 200 Hz × 10 = 2 kS/s per channel. For multi-channel setups multiply by the number of simultaneous channels to size throughput and storage.

Required sample rate (per channel) = Signal bandwidth × Samples per cycleExample: 200 Hz × 10 = 2000 samples/s (2 kS/s)

Example wiring (voltage sensor to DAQ) - ASCII

Use shielded twisted pair for low-level signals; connect shield to local earth at one point to reduce noise. For 4-20 mA loops you will need a precision shunt or DAQ with built-in current input.

Accessories and bundles we recommend

• Precision shunts and terminal blocks for industrial sensors.
• Shielded cabling, mating connectors and enclosure kits for field deployments.
• Software licences and drivers - ensure OS compatibility before purchase.

Troubleshooting common issues

If readings are noisy, check grounding, cable routing and input configuration (single-ended vs differential). If data gaps occur, confirm buffer sizes, SD card speed on loggers and network reliability for IoT setups.
