Autonics TK4N Temperature Controller — Ultra-Compact PID

Key Features and Performance

Autonics TK4N achieves what larger controllers do in a fraction of the panel space. At just 48mm wide and 24mm tall, the TK4N occupies roughly one-quarter the panel area of a standard 1/16 DIN controller. This compactness enables high-density temperature control installations — multiple zones in a single small panel — without sacrificing control performance.

Despite its size, TK4N includes PID auto-tune that calculates optimal control parameters for the connected heating system. Standard and heating-cooling control modes accommodate both simple heating applications and processes requiring active cooling for precise temperature maintenance.

The integrated CT (Current Transformer) input monitors heater element current, detecting open heater failures before they impact product quality. This diagnostic capability is particularly valuable in Malaysian manufacturing where undetected heater failure leads to production scrap — a cost that far exceeds the controller’s price.

Alarm output provides high or low temperature deviation alerts through a relay contact capable of driving indicator lights, buzzers, or external alarm systems. Configurable alarm hysteresis prevents nuisance alarm chatter around the alarm setpoint.

Multiple sensor input types include standard thermocouples (K, J) and analog signals, covering the most common temperature measurement requirements. The bright LED display remains readable at a distance despite the compact form factor, using optimised digit sizing and high-contrast design.

TK4N operates on universal 100–240V AC power or 24V DC, supporting both mains-powered panel installations and low-voltage OEM equipment designs.

Technical Specifications

Applications in Malaysian Industry

Autonics TK4N temperature controller fits Malaysian applications where panel density demands compact instrumentation. Packaging machine builders in Johor integrate TK4N into seal bar temperature control systems where 4–8 zones must fit within a small OEM control enclosure. Labelling and printing equipment manufacturers use TK4N for hot stamp and thermal transfer head temperature management.

Food service equipment companies across Malaysia deploy TK4N in commercial kitchen equipment — holding cabinets, proofing ovens, and display warmers. Small-scale plastic processing workshops in the Klang Valley use TK4N for temperature monitoring on auxiliary equipment. These OEM and compact applications support NIMP 2030 objectives by enabling smart temperature control in Malaysian-manufactured equipment.

Autonics TK4N vs Alternatives

Autonics TK4N provides PID control with CT input in a size class where most competitors offer only on-off control. The W48xH24mm form factor is smaller than the Omron E5GC and comparable to Watlow’s EZ-Zone PM Express, but with integrated heater burnout detection included at no additional cost. For applications requiring more sensor types, communication, or multiple alarms, the Autonics TZN4S upgrades to full-feature capability at a larger 1/16 DIN size.

Frequently Asked Questions

How small is the Autonics TK4N compared to standard controllers?

Autonics TK4N measures just W48 x H24mm — approximately 25% of the panel area required by a standard 1/16 DIN (45 x 45mm) controller. This allows four TK4N units in roughly the same panel space as one conventional controller.

Does TK4N include heater burnout detection?

TK4N includes a CT (Current Transformer) input that monitors heater element current. When heater current drops below the threshold — indicating an open or failed heating element — the controller generates a diagnostic alert, enabling preventive maintenance before product quality is affected.

Can TK4N handle both heating and cooling control?

TK4N supports both standard (heating-only) and heating-cooling control modes. In heating-cooling mode, the controller manages both heating and cooling outputs to maintain temperature at setpoint from both directions — useful for processes in Malaysia where ambient temperature exceeds the target.

What sensors work with the Autonics TK4N?

TK4N accepts K-type and J-type thermocouple inputs, which cover the majority of industrial temperature measurement requirements from -200°C to +1200°C. Analog signal inputs accommodate linear process signals from transmitters.

Is TK4N suitable for OEM equipment manufactured in Malaysia?

TK4N is designed specifically for OEM integration. The compact dimensions, universal power supply, and competitive pricing at volume quantities make it the preferred choice for Malaysian equipment manufacturers building temperature-controlled machines.
