DC SSR

---

STD-SPD-SLD

The STD, SLD, and SPD models are DC solid state relay modules with MOSFET technology, and 100% compatible with 5mm wide electromechanical relays. They can be soldered directly onto PCBs or plugged into all types of DIN rail standard bases.

SKLD

The SKLD relays are DC interface PCB relays with MOSFET technology. They are recommended for applications exposed to transient overcurrents (motors) and include a transil protection on the output. High-voltage models are available on request.

SOM

The SOM relays are DC solid state relays with MOSFET technology and are part of the okpac® range (Hockey puck design). They are equipped with IP20 protections and are also protected against over-voltages.

ESUC

The ESUC module, designed for the celpac 2G range and mounted on SU or SUL models, offers diagnostic monitoring for up to five parallel heating elements. It features permanent current monitoring, current teaching, and alarms for partial load breaks, open mains or load, and short-circuited SSRs.

ECOM

The ECOM is a compact, advanced control module that plugs onto celduc® SU and SUL SSRs, integrating temperature control, current monitoring, and communication in one unit. It reduces cabinet size, wiring, and PLC I/O needs while supporting thermocouple inputs, PID autotuning, MODBUS RTU communication, and alarms up to 50A — ideal for applications such as plastics, packaging, ovens, glass, and semiconductor equipment.

SMB - 2nd generation

The SMB models are two-leg, three-phase solid-state relays. Some models of the SMB second generation include a diagnostic feature.

The sightpac® series consists of three solid-state outputs controlled by one input. It has the same function as any standard solid-state relay. When the input signal is applied, each output conducts load current for its respective phase in the network.

Temperature controller, current monitor, and communication interface in one unit

The ECOM module is a compact, all-in-one temperature controller, current monitor, and communication interface designed for celpac® 2G SU and SUL SSRs. It simplifies wiring, reduces cabinet space, and minimizes PLC I/O needs. Equipped with thermocouple inputs, PID autotuning, RS485 MODBUS RTU communication, and current monitoring up to 50A, it delivers efficient and precise control for advanced industrial applications.
