The JX-1DA48 (black flip-cover housing) and KT-1DA48 (grey housing) are single-phase, DC-controlled AC solid state relays designed as direct-fit, cost-effective alternatives to Omron G3NA-style SSRs. Both variants share identical electrical specifications and the same compact physical footprint, differing only in housing style and colour. Accepting a DC control voltage of 3.2–32 VDC, these relays are directly compatible with PLC transistor outputs, microcontroller I/O, and standard industrial DC control signals. The AC load side supports 24–480 VAC at 50/60 Hz, covering 110 V, 220 V, 380 V, and 480 V systems worldwide. Load current ratings of 10 A, 25 A, and 40 A are available, with all three ratings sharing the same physical dimensions for easy interchangeability. Zero-crossing trigger technology ensures switching occurs at the natural zero-crossing point of the AC waveform, minimising EMI and extending load service life. A built-in RC snubber circuit is incorporated across all three current ratings, providing additional protection against voltage transients without requiring external components. The 10 A, 25 A, and 40 A models all use a TRIAC output stage, offering reliable bidirectional switching. An LED status indicator provides instant visual confirmation of relay activation. The panel-mount housing includes a protective cover (JX-1DA48) for added terminal protection. Private label and custom logo laser printing are available on request.

HART® is a worldwide known protocol which has been proven to be reliable and robust, TT-217 equipped with HART 7, put the electrical isolation between input and output and source, the configuration can be done via our free windows software, a HART to USB modem will be needed if you want to configure the temperature transmitter via PC, another option is to configure the unit by using various Hart field communicator.

The COMCONNECT CST-A-PT-2MS is a high-precision RTD temperature sensor designed for industrial and laboratory applications ranging from -20°C to 400°C. It features a PT100 Class A sensing element for superior accuracy and a 3-wire configuration to eliminate lead resistance errors. The sensor comes in a rugged waterproof enclosure (50.3×65.6×55.9mm) and a 2-meter shielded silicone cable (red, 3×7×0.15mm) for reliable signal transmission in harsh environments. The stainless steel probe (5×50mm) ensures fast thermal response. Customization options are available for probe dimensions, box size, and cable types.
