TT-311 is an input and output isolated din rail mounted temperature transmitter, it is 1 input and 1 output version, programmable via PC, software in English

DIN rail clamps for heatsinks and solid state relays, some of heatsinks can't be mounted to standard din rail, but the heatsink can be attached to this din rail clamps, and then mounted to a DIN rail.

The NTC10K Series is a compact, high-precision Negative Temperature Coefficient (NTC) thermistor temperature sensor housed in a rugged stainless steel M8 screw-body probe. Designed for direct installation into threaded ports on pipework, tanks, heat exchangers, and machinery, this sensor delivers accurate, low-cost temperature measurement across a wide operating range without the need for signal conditioning or cold-junction compensation.At the heart of the sensor is a precision NTC thermistor element with a nominal resistance of 10 kΩ at 25 °C and a B-value (B25/100) of 3950 K ± 1%. The thermistor element is encapsulated within a 4 mm diameter stainless steel probe, sealed with high-temperature epoxy resin to ensure moisture ingress protection. The M8 threaded body incorporates a high-temperature silicone gasket to provide a leak-proof seal when installed into a threaded port. A 150 mm flat silicone lead wire terminates in a standard 2-pin SMP (Micro-Fit style) connector for fast, tool-free connection to the host system.The NTC10K series is fully compatible with Maxwell's range of temperature controllers, as well as third-party controllers, HVAC control boards, and microcontroller-based systems that accept a passive NTC thermistor input. The sensor's small probe diameter, short lead wire, and plug-and-play connector make it an ideal drop-in component for OEM equipment manufacturers and system integrators.

The MWH300F-692 is a versatile dual-mode intelligent controller supporting both PID temperature control (thermocouple/RTD) and SCR process control (analog voltage/current). It features real-time 3-phase current/voltage monitoring, a bright dual-row digital display, and comprehensive safety protections including over-temperature, over-current cut-off, heater break/short alarm, and 3-phase unbalance detection. With RS-485 communication, PID auto-tuning, and a rugged industrial design, it ensures precise and reliable performance in harsh environments.
