DESCRIPTION

This all solid-state relay utilizes the latest technology to

provide a low ON resistance and an optically isolated output.

The control (input) and load (output) are optically isolated to

protect input logic circuits from voltage and current transients

which can occur on the output supply.

The optical isolation also provides a full floating output, thus

allowing the load to be connected to either output terminal. The

control circuit is buffered to enable the relay to be driven directly

from standard CMOS or open collector TTL logic circuits.

Available options include short-circuit and current overload

protection, which provides complete protection for both the relay

and the system wiring. This feature not only provides

protection should a short or overload occur while the relay is

on, but will also provide protection should the relay be switched

into a short. In either case, the relay will sense the short-circuit

condition and then block it indefinitely until the short is removed

and the unit is reset by cycling the input control. The second

option is a status output line. This feature is available in either

switch status or trip status configurations. Switch status returns

the true status of the output switch and is optically isolated from

the load. It provides status indication independent of the control

circuit of the relay. The status line provides a logic (0) low when

the input circuit is off and load circuit continuity is present. The

status line provides a logic 1 (high) when the output is on. Trip

status, available only with HD24 Series relays, returns a logic 0

(low) if the output trips off and a logic 1 (high) when the output is

in a normal mode (on or off). These options are available either

together or separately as standard features. Ideal for applications
