SSRs Serve As AC/DC I/O Modules

Used as an interface between logic circuitry and the load and ideal for MRO, HVAC and packaging machinery applications, the G3TC Series of solid-state I/O modules has a built-in hold-down screw that fastens the relay to the pc board to prevent loosening by vibration. The SSRs are classified, per industry standard, by color: red for dc output and white for dc input, and black for ac output and yellow for ac input. The ac input modules can be powered by 90-140 or 180-280 Vdc/Vac, while dc input modules can operate from 10-32 Vdc/Vac, with a logic-level output supply voltage of 5-24 Vdc on both ac and dc input modules. Depending on model, the load for ac output modules is 3A at 75-280 Vac, and rated input voltage is 5-24 Vdc. The dc output modules' applicable output load is 3A at 5-60 Vdc and 1A at 5-200 Vdc.The G3TCs are UL and CSA approved, conform to CE, and have a starting price of $10.10 each.
