| Solid State
Relays (SSRs) are electronic switching devices that accept a time proportioned
or on/off signal from a controller. Rapid cycling can wear out electro-mechanical
relays, whereas SSRs operate at much smaller cycle times. Therefore, Solid
State Relays (SSRs) can be employed where extremely tight process control
is required and when durability is a necessity. The life of a heating
element is increased considerably when the on/off cycle that is used to
time-proportion the heater is kept at 1 or 2 seconds, or less, thus reducing
the thermal expansion and contraction of the element. The fast cycling
SSRs ensure longer heater life at lower cost. In addition, temperature
control is optimized with the faster cycling Solid State Relays (SSRs)
compared to electro-mechanical relays.
Since Solid State Relays (SSRs) have
no moving parts, mechanical failure is eliminated. They are resistant
to shock and vibration and are durable if operated within the tolerable
ambient temperatures. Heat-sinks will efficiently dissipate the heat
thereby increasing each unit’s life.
Featuring state-of-the-art surface mount
technology, Solid State Relays (SSRs) come in a number of configurations
with different mounting options. They are compact, typically measuring
57(H) x 44(W) x 22(D)mm. They accept AC or DC control input voltages
with DC or AC output at 10-75A. They are available in both general purpose
and heavy duty styles. Heavy duty style SSRs operate on higher voltage
(480V AC) and will withstand high currents and harsh industrial environments.
Other features include photo isolation, 600 volt blocking voltage, 2500
volt isolation, zero voltage turn-on, built-in snubber, and high surge
capability.
