R-10T

Multi-Voltage Conventional Relays System Sensor’s multi-voltage conventional relays are used for high-current switching applications such as fan and damper assembly control, door control, air handling unit controls, and other types of system interfacing. Features • Multi-voltage operation • Activation LEDs • Easy and flexible installation • Reliable and robust design • Multipurpose field installations • Multi-voltage relays with terminal strip field wiring connections, mounting track, and hardware for R-10T/20T and R-14T/24T • Removable front cover on steel enclosure for R-10E/R-20E and R14/R-24E, which mount inside the enclosure • LED viewing hole on top of the steel enclosure’s cover • Extra pair of wires for redundant power input on PR-3 • Terminal strip field wiring connections, mounting track, and hardware The R-10T, R-20T, R-14T, and the R-24T models are multivoltage relays with terminal strip field wiring connections, mounting track, and hardware. The R-10T is a single FORM–C (SPDT) relay with a red activation LED, and the R-14T is a four-gang 1 FORM–C (SPDT) relay with four red activation LEDs. The R-20T is a single 2 FORM–C (DPDT) relay with a red activation LED, and the R-24T is a four-gang 2 FORM–C (DPDT) relay with four red activation LEDs. The R-10E/R-20E and R-14E/R-24E 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. PR-1/PR-2/PR-3 are epoxy encapsulated multi-voltage relays. They are single-pole double-throw relays that use a red LED as a visible indication of relay coil energization. PR–3 is identical to PR–2, except it has an extra pair of wires for redundant power input. Model EOLR-1 is an epoxy encapsulated, single-pole single-throw, normally open relay that can be used as an end of line device in fire alarm systems, e.g. to supervise power supplies.
