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.

The MKD2 Series is a single-phase, dual-channel, DC-controlled AC solid state relay (SSR) designed for reliable, silent switching of resistive and inductive AC loads in industrial and commercial control systems. Each unit houses two independent switching channels within a single compact black housing, enabling two separate AC loads to be controlled simultaneously from a single device — saving panel space and wiring time compared to installing two separate SSRs.

The MKD2 accepts a DC control voltage of 4–32 VDC, making it directly compatible with PLC outputs, microcontroller I/O, and standard industrial control signals. The AC load side supports voltages from 24 to 480 VAC, covering 110 V, 220 V, 380 V, and 480 V systems worldwide. Load current ratings of 25 A, 40 A, 60 A, and 80 A are available, with all variants sharing the same physical footprint for easy interchangeability.

Zero-crossing trigger technology ensures that switching occurs at the natural zero-crossing point of the AC waveform, minimising electrical interference (EMI) and extending the service life of both the relay and the connected load. Individual LED status indicators for each channel provide instant visual confirmation of relay state, simplifying commissioning and fault-finding. The unit is CE certified and constructed from fire-retardant ABS with a dielectric strength of 2500 Vrms between input, output, and base.

FL-SSR is a DIN rail mount solid state relay , DC input AC load version, heatsink integrated with SSR, available with 10A, 25A, 40A, 55A.
