ZD20CF Series 2A, 60A Optically Isolated Short-Circuit Protected Part* Relay Number Description ZD20CF* 2A, 60 Vdc, short-circuited protected up to 33 Vdc, solid-state relay for through-hole mounting SZD20CF* 2A, 60 Vdc, short-circuited protected up to 33 Vdc, solid-state relay for surface mount *W for +25C ambient T for over-temperature screen FEATURES Short-Circuit protected ELECTRICAL SPECIFICATIONS (55C to +105C ambient temperature unless otherwise specified) Overload protected 2 Amp load Low off-state leakage INPUT (CONTROL) SPECIFICATIONS Optical isolation Min Max Units compact 6-pin package Input Current 8 20 mA DESCRIPTION Input Voltage 10mA 2 3 Vdc ZD20CF Series Relays have optical isolation be- Must Turn-On 8 mA tween relay input and output. Load may be con- Must Turn-Off Current 100 A nected to either the positive or negative output terminals. ZD20CF Relays act as electronic circuit Reverse Polarity -6 Vdc breakers that sense shorted loads or other over- load events and then trip-off. Relay contacts open OUTPUT (LOAD) SPECIFICATIONS and no current flows through the relay and as - sociated loads. These relays prevent overcurrent Min Max Units damage to the system. Cycloing the relay on-off Load Voltage Range 0 60 Vdc removes the tripped or latched-off condition and Output Current Rating (See Figure 5) 2.0 A returns the relay to the normal operating state.
