REH Series Power Relay
Industrial power relay with 2- and 3-pole contacts rated 16 A, an integrated non-polarity LED, and a lockable test button with inspection window; coil type is identified by test-button colour (AC red / DC blue). RoHS compliant.
RGF Series Power Relay
Heavy-duty power relay rated 30 A (1-pole) and 25/40 A (2-pole) with top-mounted quick-connect terminals, a DIN-rail locating slot, and an IP20 finger-protection cover - used for large loads such as air-conditioning and refrigeration.
RFT Series Interface Relay
Slim, compact interface relay rated 12 A (1-pole) and 8 A (2-pole) with an integrated non-polarity LED and lockable test button; mounts on a DIN-rail socket with bus-jumper wiring to couple PLC and controller signals.
RNC Series Interface Relay Module
Ultra-slim 6.3 mm interface relay module - high sensitivity, low power draw, and a 6 A maximum load - with a bridge rectifier and built-in surge absorber for AC/DC, for PLC, CNC, and robot output-signal and safety-drive interfacing.
RKE Series Miniature General-Purpose Relay
Miniature plug-in general-purpose relay rated 5 A (250 VAC / 30 VDC), supplied with DIN-rail sockets and optional LED and surge-suppression coil modules for control-panel switching.
RKL Series Miniature Power Relay
Miniature plug-in power relay rated 15 A (250 VAC) with an optional LED module, for compact switching of higher-current loads in industrial control panels.
RUB Series General-Purpose Relay
Plug-in general-purpose relay rated up to 15 A (250 VAC / 30 VDC) with an integrated LED module and matching sockets, for switching and control in machine and panel builds.
RSD Series AC/DC Solid-State Relay
Panel-mount solid-state relay (1 N/O, SPST) with MOSFET output for DC and TRIAC/SCR output for AC, optocoupler isolation, an LED indicator, and a metal cooling base plate - for temperature control, furnace heating, CNC, and motor control.
RSC Series Solid-State Slim Relay
Slim DIN-rail solid-state relay interface (SNC05) with 6–24 VDC input and AC or DC output modules - a compact, contactless alternative to electromechanical interface relays for fast, silent switching.
PCB Relays
Board-mount signal and power relays for direct PCB soldering - from subminiature signal relays to miniature power relays - for appliance electronics, control boards, and electronic manufacturing.
TKB Series Timer Relay
Miniature IC-controlled timing relay with screwdriver-set delay and a fast midway reset (under 100 ms); TKB2 and TKB4 models rated 120/230 VAC and 24 VDC with up to 5 A output, for lighting, heating, and motor-start timing. Conforms to IEC 60947-5-1 and mounts on matching SKB/SKC sockets.
Relay Protection Modules & Accessories
Coil-protection and status-indication modules - RC, free-wheel diode, and MOV/varistor types (AMD and BMD series) - plus sockets, retaining clips, and marker accessories that suppress coil kickback and extend the life of the relay and its driving circuit.
