PEACOCK C-5 VER.3 Replacement/Upgrade Solution for C-5 Series

Product Overview

PEACOCK C-5 VER.3 Replacement/Upgrade Solution for C-5 Series: Smooth Transition from Legacy Digital Counters

When your production line depends on a PEACOCK C-5 VER.3 digital counter and the original unit reaches end-of-life or becomes unavailable through standard distribution channels, unplanned downtime is the immediate risk. TOPNLMS supplies verified PEACOCK C-5 VER.3 units sourced directly from authorized channels, pre-tested before dispatch, and shipped from our Xiamen warehouse to minimize the gap between failure and restoration. Whether you are managing a scheduled retrofit, responding to an emergency breakdown, or building a strategic spare-parts inventory, the C-5 VER.3 is available for immediate fulfillment.

The C-5 VER.3 is a compact electromechanical-to-digital transition counter designed for industrial counting, batching, and totalizing applications. It is widely deployed in packaging machinery, press lines, injection molding equipment, conveyor systems, and general-purpose factory automation panels. Its DIN rail-compatible housing and standardized terminal layout make it a practical drop-in candidate for panels originally built around earlier PEACOCK C-5 variants, including the C-5 VER.1 and C-5 VER.2, without requiring panel re-engineering or significant rewiring effort.

Seamless Upgrade Solutions

A counter replacement rarely occurs in isolation. In most industrial retrofit projects, the C-5 VER.3 is installed alongside a broader set of panel components that must be verified or simultaneously upgraded to ensure system integrity. During the migration from an older PEACOCK C-5 series counter, engineers typically review the associated power supply module — commonly a 24 VDC DIN rail PSU such as a MEAN WELL MDR-60-24 or equivalent — to confirm that the inrush current profile of the new counter does not exceed the supply’s derating curve at operating temperature.

Terminal blocks and wiring accessories are another practical consideration. When the original panel used PHOENIX CONTACT UK 2.5 or WAGO 281-series terminal blocks, the C-5 VER.3’s screw terminal pitch is compatible without adapter plates, simplifying the physical installation. If the existing wiring harness uses ferrule-terminated conductors, no re-termination is required beyond confirming torque specifications.

In systems where the counter interfaces with a programmable logic controller — for example, a MITSUBISHI MELSEC FX3U series or an OMRON CP1H — the pulse output from the C-5 VER.3’s relay contact feeds directly into a digital input module such as the MITSUBISHI FX3U-16EX or OMRON CJ1W-ID211 without signal conditioning, provided the PLC input voltage matches the counter’s relay contact rating. Where the legacy system used a PEACOCK C-5 VER.2 with an RS-232 serial link to a supervisory controller, the optional RS-485 variant of the C-5 VER.3 enables a direct protocol-compatible upgrade path, eliminating the need for an RS-232/RS-485 converter module.

For applications where the counter drives a downstream batch control relay or a SCHNEIDER ELECTRIC ZELIO logic module, the C-5 VER.3’s dual-stage preset relay outputs map directly to the existing control logic without PLC program modification, provided the preset values are re-entered during commissioning. In conveyor and packaging line applications, the counter is frequently installed in the same control cabinet as a KEYENCE FS-N series fiber optic sensor amplifier or a SICK WL series photoelectric sensor, both of which provide NPN pulse outputs fully compatible with the C-5 VER.3’s input stage.

Where panel space is constrained and the original installation used a 48×48 mm format counter, the C-5 VER.3’s compact footprint fits the same cutout dimension, avoiding panel modification. In larger control cabinets housing SIEMENS SIMATIC S7-1200 or S7-300 PLCs with existing I/O expansion racks, the counter operates as a standalone totalizer, offloading high-frequency pulse counting from the PLC’s onboard HSC (high-speed counter) inputs and reducing scan-cycle load on the main CPU module.

Retrofit Guidance FAQ

Q: Can I replace a PEACOCK C-5 VER.2 with the C-5 VER.3 without rewiring the panel?
In most cases, yes. The terminal layout of the C-5 VER.3 is backward-compatible with the VER.2. You should cross-reference the terminal numbering on your existing wiring diagram against the C-5 VER.3 datasheet before energizing. Pay particular attention to the reset input terminal and the output relay common terminal, as minor renumbering occurred between revisions.

Q: Does the C-5 VER.3 support the same pulse input types as the original unit?
The C-5 VER.3 accepts contact closure, NPN open-collector, and PNP open-collector pulse inputs. If your existing sensor is NPN (the most common type in Japanese and Chinese industrial installations), no signal conditioning is required. Confirm the input voltage range matches your sensor’s output specification.

Q: Will I need to modify my PLC program after replacing the counter?
No PLC program modification is required if the counter is used in standalone mode with relay output to PLC digital inputs. If the legacy system used serial communication (RS-232) between the counter and a supervisory system, you should evaluate whether the optional RS-485 variant of the C-5 VER.3 is appropriate, or whether a protocol converter is needed to maintain the existing communication architecture.

Q: What is the physical installation space requirement?
The C-5 VER.3 uses a standard 48×48 mm panel cutout (DIN 43700 compliant) with a mounting depth of approximately 80 mm behind the panel face. Verify rear clearance in your control cabinet before installation, particularly in densely populated panels where cable management may restrict depth.

Q: How do I handle the preset value migration from the old unit?
Preset values are stored locally on the counter and are not transferable electronically. Record all preset values from the existing unit before removal. Re-enter them during commissioning of the C-5 VER.3 using the front-panel keypad. If the original unit is non-functional, preset values should be retrieved from the original commissioning documentation or process engineering records.

Q: Is the C-5 VER.3 compatible with 24 VDC panel power supplies?
Yes. The C-5 VER.3 supports both 100–240 VAC and 24 VDC power supply inputs (dual-range). Confirm the power supply variant when ordering, as AC and DC versions use different internal power stages and are not field-convertible.

Warranty Assurance

Every PEACOCK C-5 VER.3 unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes functional verification including power-on self-test, input signal response check, relay output continuity verification, and display function confirmation. Units that do not pass pre-shipment inspection are quarantined and not shipped.

In the event of a warranty claim, TOPNLMS provides replacement unit dispatch within 3 business days of claim confirmation, subject to fault verification. Customers are not required to return the defective unit before a replacement is dispatched for critical production applications — contact our sales team to arrange advance replacement under warranty.
