Solid State Relays Industrial, 2-Pole ZS Type RA2A 2-Pole AC Solid State Relay Zero switching For resistive and inductive AC loads Direct copper bonding (DCB) technology LED indication Rated operational current: 2 x 25 and 2 x 40 AACrms Rated operational voltage: 230 - 600 VACrms Input range: 4.5 - 32 VDC Blocking voltage: Up to 1200 Vp Opto-isolation: 4000 VACrms Product De scrip tion Ordering Key RA 2 A 48 D 25 M This 2-pole industrial relay to control B. LEDs indicate Solid State Relay minimises the space require- the control status of each Number of poles ments in a control cabinet pole. The optimised design is Zero switching without compromising per- free of moulding mass to Rated operational voltage formance. By applying an reduce internal mechanical Control voltage input voltage on control A, stress. Rated operational current the corresponding output Load type semicondcutor is activated at The RA2A..M types have the first zero crossing of the been specially customised for line voltage.The same applies demanding inductive loads.
