About Delta Electronics Industrial Automation

Delta Electronics is a Taiwanese multinational OEM manufacturer covering industrial automation, power electronics, and energy management products, with Delta's Industrial Automation Business Group producing PLCs, HMIs, servo drives, VFDs, and panel instrumentation including the CTA counter series.

Delta's automation products are positioned as value-to-mid tier in the global industrial market - competitive pricing versus Mitsubishi and Siemens tier-1 systems while offering a cohesive ecosystem of PLC, VFD, servo, HMI, and panel instruments with native communication between product families. In Malaysia, Delta has established distributor presence across Klang Valley, Penang, and Johor Bahru, with Malaysian system integrators building complete Delta-brand automation panels for SME manufacturers in F&B, rubber, and general manufacturing.

Delta Counter Product Lines

Delta CTA-SS is the standard standalone panel counter for Delta-ecosystem plants - 6-digit red LED display, single-preset and totalising modes, relay contact output. The CTA-SS integrates with the Delta PLC system via relay output to a digital input module - straightforward wiring without communication overhead.

Delta CTA-SSD adds a second display row showing both the preset setpoint and the current count simultaneously - eliminating the need for operator to enter parameter mode to verify the current setpoint during production operation. RS485 communication via Delta DMCA protocol enables Delta PLC to read count values and modify setpoints programmatically without operator front-panel interaction.

Technical Specifications

Delta CTA series counters meet standard Malaysian industrial panel instrument electrical requirements.

Supply voltage: 100-240 VAC 50/60 Hz or 12-24 VDC depending on model suffix. Malaysian 230 VAC 50 Hz single-phase supply is within the operating range of standard AC-powered CTA models.

Input signal types: NPN open-collector and PNP inputs at 24 VDC logic level, compatible with standard Malaysian proximity sensors and encoder outputs. Voltage-type inputs are also accepted at 12-24 V levels.

Maximum input frequency: Up to 30 kHz - sufficient for all standard conveyor-speed and moderate encoder-speed applications encountered in Malaysian SME manufacturing. Applications requiring pulse counting above 30 kHz require a PLC-based HSC module, not a standalone panel counter.

Output: Relay contact output (250 VAC / 5 A, 30 VDC / 5 A) on CTA-SS models provides compatibility with standard contactor coil and indicator lamp loads in Malaysian control panels. CTA-SSD adds transistor output for PLC digital input triggering without relay contact wear.

Operating environment: 0-50°C ambient, 35-85% relative humidity non-condensing. Panel-mount installation inside sealed enclosures - IP40 front panel protection. Malaysian factory floor environments require IP54 or IP65 enclosures housing the counter.

Why Delta Counters for Delta-Ecosystem Plants

Delta counters offer one specific advantage within a Delta-standardised automation plant: native RS485 communication via Delta DMCA protocol (CTA-SSD series), allowing Delta DVP and AS-series PLCs to address the counter as a peripheral device without RS485-to-Modbus translation gateway hardware.

For Malaysian plants operating Mitsubishi, Siemens, or Panasonic PLCs, Delta counter RS485 communication is not directly compatible - those PLCs use Modbus RTU or manufacturer-specific protocols that do not natively map to Delta DMCA. In mixed-brand panels, Autonics MP5 series (RS485 Modbus RTU) provides broader PLC compatibility for counter communication.

Same-brand ecosystem alignment in Malaysian SME automation plants reduces commissioning time by eliminating protocol gateway hardware and consolidating vendor technical support to a single point of contact. Delta counters, Delta PLCs, Delta VFDs, and Delta servo drives operate under the Delta DIADesigner and DIAStudio software environment - a single-programming-tool advantage that Flextech recommends for Malaysian plant engineers standardising on Delta automation.

Applications in Malaysian Manufacturing

Food and beverage packaging - Delta CTA-SS counters on bottle and pouch filling lines count units per batch, with relay output triggering conveyor transfer signals when batch count is complete. Delta PLC on the same panel reads the counter status without additional wiring.

Conveyor speed monitoring - Delta CTA-SS totalising mode accumulates encoder pulse counts from a conveyor drive shaft, enabling production throughput calculation in units-per-hour when counter resets are triggered by PLC output on shift change.

Injection moulding shot counting - Delta CTA-SS with machine auxiliary output relay totalises moulding shots for mould maintenance interval tracking - a standalone function that requires no PLC programming overhead in Delta or non-Delta controlled moulding machines.

Batch weighing control - Delta CTA-SSD with RS485 communication in Delta PLC-controlled batch weighing systems allows the PLC to write batch setpoints remotely based on recipe selection, without operator front-panel counter programming.

Genuine OEM Delta Counters vs Grey-Market Risk

Delta products - including CTA counters - are subject to parallel import and grey-market distribution in Malaysia. Grey-market Delta counters may appear identical to genuine OEM products but carry no authorised warranty, may contain non-Delta components inside Delta-branded enclosures, and fail Delta serial number verification.

Genuine OEM Delta counters from Flextech carry Delta Electronics hologram labels, traceable serial numbers, CE/RoHS certification, and Flextech's authorised distributor documentation. For industrial applications where counter failure disrupts production, grey-market risk is not justified by unit price differences.

Delta Counter FAQ

What Delta counter series does Flextech stock in Malaysia?

Flextech stocks Delta CTA-SS and CTA-SSD series panel counters. CTA-SS is a single-preset 6-digit counter; CTA-SSD adds dual-display and RS485 Delta DMCA communication.

Do Delta counters integrate with Delta PLCs via RS485?

Delta CTA-SSD series supports RS485 communication using Delta DMCA protocol, enabling Delta DVP and AS-series PLCs to read count values and write preset setpoints directly.

Are Delta counters compatible with non-Delta PLCs?

CTA-SS relay outputs connect to any PLC digital input. CTA-SSD RS485 uses Delta DMCA protocol - not Modbus RTU - so non-Delta PLCs cannot natively communicate with it. Specify Autonics MP5 (Modbus RTU) for mixed-brand panel counter communication.

What is the price range for Delta counters in Malaysia?

Delta CTA-SS models range from approximately RM 120-280. CTA-SSD communication models range from RM 300-550. Contact Flextech for a current quote.

Are Delta counters suitable for Malaysian factory environments?

Delta CTA series counters are rated for panel-mount installation inside IP40+ enclosures at 0-50°C and up to 90% non-condensing relative humidity. Install inside sealed IP54 or IP65 control enclosures for Malaysian factory environments.
