Why buy locally from Communica

Fast availability, multiple pickup points and practical buying terms are the benefits that matter to engineers and students. We hold local inventory at our Samrand head office with branch collection options in Pretoria CBD and Cape Town. For larger orders or departmental purchases, account quotes and VAT invoices are available to streamline procurement.

• Stocked parts for prototyping and production: PCB timers, relay timers, digital counters and multifunction modules.
• Branches & same-day collection options - check branch stock or reserve for pickup in Samrand or other locations.
• Technical selection help and practical application notes for classroom and workshop use.

Quick specification guide

When choosing a timer or counter, consider supply voltage, contact/current rating, timing range, accuracy, input type (pulse, open-collector, TTL) and mounting format (PCB, DIN-rail, panel). Below is a concise comparison to help you match a product to your project.

Compatibility and accessories

Most modules are designed for common control voltages; check datasheets for compatible relay/contact ratings. We also stock complementary items such as sockets, panel cutouts, DIN-rail adaptors, protective enclosures and wiring supplies so you can order complete assemblies. For part discovery, browse our categories or brands to compare options: Shop by Category, view brands we stock, or explore our full range on the All Products page.

Specification callouts - examples

Below are common spec snippets to look for on datasheets and product pages so you can quickly compare parts before purchase.

If you need part-specific help, our product pages include datasheets where available. Learn more about Communica’s history and service ethos on our About Us page.

Selection help, wiring tips and practical examples

We help you pick the right timer or counter based on application. For example, choose a relay-output timer for mains switching, a solid-state output for low-power control, and a TTL-compatible counter for microcontroller interfaces. If your design uses microcontrollers, opt for modules with clear pulse-input requirements or select PCB-mounted timers designed for breadboards.

Simple wiring diagram (ASCII)

Below is a common wiring layout for a 24V power supply, a timer module and a load controlled via the timer relay.

24V + -----+----[ TIMER V+ ]            |               |           [ PSU ]         [ TIMER OUTPUT (COM/NO) ]---> LOAD24V - -----+----[ GND ]

Quick calculations

Use Ohm's law and power formulas when sizing loads or inline resistors. Common reminders:

V = I × R (Voltage = Current × Resistance)

P = V × I (Power = Voltage × Current)

Example: a 24V relay driving a 2A heater requires wiring rated above 2A and a relay contact rating above 2A; choose appropriate fuse and wire gauge.

Availability, lead times and procurement notes

Many popular timers and counters are held in local stock for immediate collection or same-day dispatch from our Samrand warehouse. For specialist or bulk orders, lead times vary by brand - check real-time availability on product pages or timers and counters in stock to arrange pickup. Education and tertiary customers can request pro-forma invoices and bulk quotes to simplify departmental purchasing.

Troubleshooting & common issues

If a timer does not trigger, check supply polarity and minimum operating voltage first. For counters missing pulses, verify input debounce, pulse width and wiring (open-collector vs TTL). Our product listings link to datasheets and wiring notes so you can verify requirements quickly. If you need hands-on help, contact our technical team or visit the Samrand branch for consultation.
