TELI CS3500C Replacement/Upgrade Solution for CS3500

Product Overview

TELI CS3500C Replacement/Upgrade Solution for CS3500 Series: Seamless Transition for Industrial Vision Systems

The TELI CS3500C is a Camera Control Unit (CCU) from TELI’s CS3500 Series, designed for demanding industrial machine vision and inspection applications. As production lines age and original TELI CS3500C units reach end-of-life or become increasingly difficult to source, engineering teams face the critical challenge of maintaining uptime without disrupting validated inspection processes. This page provides a complete migration and replacement guide for facilities transitioning from legacy TELI camera control hardware to a verified CS3500C unit — ensuring electrical, mechanical, and functional compatibility at every step.

Whether your facility operates a standalone vision inspection cell or integrates the CS3500C into a broader PLC-coordinated production line — such as systems built around OMRON CJ2M or Mitsubishi Q-Series controllers — the CS3500C’s standardized interface architecture allows for a direct swap with minimal re-engineering. The unit retains the same physical footprint and connector layout as earlier CS3500 Series variants, meaning existing cable harnesses, mounting brackets, and control cabinet cutouts remain fully usable during the retrofit.

Seamless Upgrade Solutions

A successful CS3500C retrofit rarely involves replacing the camera control unit in isolation. In most industrial vision installations, the CCU sits at the center of a tightly integrated system, and a smooth migration requires attention to every adjacent component in the signal chain.

Starting at the image acquisition layer, the CS3500C interfaces directly with TELI CS3500-series camera heads. If the camera head itself has degraded alongside the CCU, sourcing a matched CS3500-series camera head simultaneously eliminates the risk of compatibility mismatches and avoids a second maintenance window. For facilities using older coaxial video cabling, verifying cable impedance and connector integrity before commissioning the replacement CCU is strongly recommended.

On the control side, the CS3500C receives trigger signals from upstream automation controllers. In lines where a KEYENCE CV-Series vision controller or a Cognex In-Sight sensor previously handled inspection logic, the CS3500C’s standard trigger I/O allows direct wiring to existing PLC output modules without signal conditioning. For Mitsubishi MELSEC Q-Series or iQ-R Series PLC installations, the digital output module (such as a QY40P or RY40NT5P) can drive the CS3500C trigger input directly, preserving existing ladder logic without modification.

Lighting control is another area where migration planning pays dividends. Many CS3500 installations use a dedicated strobe controller — such as a CCS PD2 or Gardasoft RT200 — synchronized to the CCU’s strobe output. The CS3500C’s strobe output signal is electrically compatible with these controllers, so existing lighting timing parameters carry over without recalibration.

For facilities that route inspection results to a higher-level SCADA or MES system via RS-232 serial communication, the CS3500C’s serial port configuration (baud rate, data bits, stop bits) should be matched to the existing host system settings during commissioning. A USB-to-RS232 adapter or a dedicated serial communication module — such as a Moxa NPort 5110 — can bridge legacy serial output to modern Ethernet-based supervisory networks if an infrastructure upgrade is planned in parallel.

Finally, power distribution within the control cabinet should be reviewed. If the existing 24 VDC rail is shared with other devices — such as a Phoenix Contact QUINT power supply feeding multiple I/O modules — confirm that the available current budget accommodates the CS3500C’s consumption without triggering overcurrent protection on the shared rail.

Retrofit Guidance FAQ

Q: Can I reuse existing wiring when replacing the old CS3500 CCU with the CS3500C?
A: Yes. The CS3500C maintains the same connector pinout as earlier CS3500 Series units. Power, trigger, strobe, and video connectors can be transferred directly without rewiring, provided cable condition is verified before reconnection.

Q: Will my existing PLC program require modification after the swap?
A: No program changes are required for the PLC controlling the trigger and strobe I/O. The CS3500C responds to the same signal levels and timing as its predecessor. If inspection result data is parsed by the host controller, verify that the RS-232 data format output by the CS3500C matches the expected frame structure in the existing communication routine.

Q: Is the CS3500C compatible with third-party camera heads from other manufacturers?
A: The CS3500C is optimized for TELI CS3500-series camera heads. Compatibility with third-party camera heads depends on the video standard (CCIR/EIA) and sync format. Contact our technical team with your camera head model for a compatibility assessment before ordering.

Q: How much physical space does the CS3500C require in the control cabinet?
A: The CS3500C shares the same form factor as the original CS3500 Series CCU. No cabinet modifications, additional DIN rail space, or new cutouts are required for a direct replacement installation.

Q: What communication protocols does the CS3500C support for host system integration?
A: The CS3500C supports RS-232 serial communication for host control and data output. For integration with Ethernet-based supervisory systems, a serial-to-Ethernet converter can be used without modifying the CCU’s internal configuration.

Q: What is the lead time and shipping arrangement?
A: Units are stocked in Xiamen and ship within 1–3 business days of order confirmation. International express delivery (DHL / FedEx) is available. All units undergo functional testing prior to dispatch.
