L62 Limit Controller
Safety Precision Built In
Enhancing industrial safety with advanced limit control
The L62 Limit Controller from BrainChild delivers fast, stable, and precise limit protection in space-limited industrial applications. Its compact 1/16 DIN design integrates universal sensor input, dual outputs (relay or SSR), fast 200ms sampling, and RS-485 Modbus communication for remote integration. It offers flexible alarm logic, event inputs, analog retransmission, and an optional third output channel, making it ideal for over-temperature protection in heating systems or control cabinets. With a dual-line LCD, Micro USB setup port, and BC-SET Pro support, the L62 simplifies both configuration and firmware updates. Robust front-panel operation and flexible output logic make it suitable for OEM integration or on-site safety upgrades.
Intuitive Dual Display with 4-Key Control
Simplify setup and monitoring on-site with ease
L62 features a high-visibility dual-line LCD: the upper line shows the process value (PV), unit, menu code, or error messages, while the lower line displays setpoint (SP) or parameter data. Dedicated output and lock status indicators help users instantly confirm system status. The membrane keypad includes 4 responsive buttons that enable fast access to menus, parameter editing, and alarm resets. The clean interface is optimized for OEMs and operators needing quick verification and minimal training.
Multi-Sensor Input with High Precision
Supports TC, RTD, mV, V, and mA signals
L62 supports multiple sensor inputs including thermocouples (J, K, T, E, B, R, S, N, L, P, C), RTD (PT100 DIN/JIS), mV (0–60mV), current (0–20mA), and voltage (0–1V, 0–10V). All types are selectable via keypad or software. An integrated 18-bit A/D converter ensures fast and accurate conversion. The unit auto-compensates for sensor differences, making it suitable for heat treatment, oven, or safety-critical system monitoring.
Dual Output with Alarm Logic Options
Relay or SSR drive with 3rd output available
Output 1 and Output 2 can be set as relay contact (2A/240VAC) or SSR drive (5V/14V). An optional Output 3 is available for expanded alarm logic. Users can program high, low, or deviation alarms, as well as choose latching or normal reset behavior. Optional analog retransmission (4–20mA or 0–10V) provides PV feedback to recorders or PLCs. The flexible logic makes L62 suitable for shutdown, alarm, or interlock applications.
USB-Based Offline Configuration
Use BC-SET Pro software for fast setup and cloning
The L62 features a built-in Micro USB programming port on the front panel, providing engineers with a fast and convenient way to configure devices without entering menu layers manually. Using BrainChild’s BC-SET Pro software along with the CC98-1 cable and PA98-1 adapter, users can perform offline parameter setup, firmware upgrades, and device cloning with ease. This functionality is especially useful in OEM or batch deployment scenarios where consistent configuration across multiple controllers is essential. The programming port also supports ATE (Automated Test Equipment) environments, offering a standardized interface for production-line testing, calibration, or mass firmware initialization prior to delivery. Note: The port should only be used when the controller is powered and not in active process operation.
BC-SET Pro Configuration Software
Easy parameter setup, backup and firmware upgrade
BC-SET Pro is the official configuration software developed by BrainChild for its over-temperature protection controllers. With a streamlined and intuitive interface, the software allows users to connect via USB programming cable and quickly configure control parameters. It supports efficient parameter editing, setting duplication between devices, and firmware upgrades to maintain device performance and stability. BC-SET Pro also enables offline configuration with the ability to save and manage multiple profiles, making it ideal for production environments, system deployment, and ongoing maintenance. Whether for new setup or existing system adjustment, this tool helps engineers and technicians simplify workflow, reduce setup time, and ensure consistent configuration across all devices.
Batch Read/Write for Multiple Controllers
BC-SET allows users to connect multiple controllers of the same model and perform batch parameter read/write by defining a node address range. This feature significantly streamlines configuration in OEM or multi-device environments.
Clear and Accessible System Menu
The system menu offers quick access to key operations like Rescan (F5), Read Data (F6), Write Data (F7), Write Multiple (F8), and Communication Settings (F9). Built-in hotkeys support fast, efficient navigation.
Intuitive Communication Setup Interface
The communication settings window lets users define COM port, baud rate, parity, data bits, and stop bits — with a “Default” button for quick reset and “Save and Exit” to finalize setup. Designed to reduce setup errors.
Visual Profile Editor for Programmable Controllers
For controllers with profile functionality, BC-SET provides a graphical editor to configure temperature ramp/soak segments. Users can easily read, modify, and write profile parameters for precise thermal process control.
Certified Safety and Environmental Design
IP50 front, IP20 terminals, and UL/CE approved
The L62 offers IP50 protection on the front panel and IP20 on the terminal section, ensuring solid protection against dust intrusion and accidental contact with live components. This makes it highly suitable for integration into electrical control panels, automation enclosures, and industrial cabinets where safety and component durability are critical. The controller complies with UL61010, CE, FM3545, EN61010-1, and RoHS standards, which confirms its suitability for use in regulated environments and across global industrial markets. Its rugged housing and standardized safety certification ensure long-term reliability even under continuous operation or frequent installation cycles.
