The R-10TA, R-20TA, R-14TA, and the R-24TA models are multi-voltage relays with terminal strip field wiring connections, mounting track, and hardware. The R-10TA is a single FORM–C (SPDT) relay with a red activation LED, and the R-14TA is a four-gang 1 FORM–C (SPDT) relay with four red activation LEDs. The R-20TA is a single 2 FORM–C (DPDT) relay with a red activation LED, and the R-24TA is a four-gang 2 FORM–C (DPDT) relay with four red activation LEDs. The R-10EA/R-20EA and R-14EA/R-24EA are similar to the T-series track mount relays, but they are mounted into a steel enclosure. The enclosure has a removable front cover that provides easy access and an LED viewing hole on the top of the cover.
