Cost effective PID Temperature controller, available with all major sizes, Relay+SSR Drive output as standard options. Other outputs such as 4-20mA and 0-10Vdc also available. TC/RTD inputs , Relay and SSR Drive output are two of most demanding outputs, this feature makes this controller accomendate to most of applications

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.
