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.

Maxwell DR8F-T-U06 is a din rail mount 8 input 8 transistor outputs I/O modules, input can be NPN or PNP input, 8 NPN transistor output can be controlled from master device like HMI or PLC, the input work independently apart from output.

● Digital programmable counter● 48mm*48mm,Dual line 4 digits display● Panel mount type● Dry contact, NPN input● Maximum 2 outputs(OP1 and OP2)● 85~265Vac or 24VDC source● SV counting/Batch counting/Totalizing count

● Single phase high accuracy SCR● Support all kinds of analog signal● 220Vac or 380Vac load● From 40 amps up to 200 amps● Phase angle firing control

This is a single phase SCR power regulators and temperature controllers 2 in 1 units, in a typical heating system, you would need a temperature controller and a SCR power regulators, and they are two separate devices, we go further and build this two devices in one package, this saves a lot of efforts for panel builders when it comes down to wiring, and RS-485 modbus is a standard feature, controller can be integrated to systems with HMI or PLC etc. the load can be directed wired to this thyristor power regulators, and it works with all kinds of inputs, Thermocuple, RTD, analog signal

● Incremental rotary encoder● 25mm housing diameter● 4mm solid shaft● Maximum 1200 PPR● Push-pull, NPN,PNP, Line driver, voltage output● Cable rear entry, cable length customizable
