Tempatron Monitoring Relay SPDT DIN Rail 200 to 10,000 rpm, 110V AC, 230V AC, 24V DC FSST-110/230VAC

Tempatron FSST-110/230VAC monitoring relay is an industrial-grade SPDT relay mounted on a DIN rail, designed for precise rotational speed monitoring of machinery with speeds ranging from 200 to 10,000 rpm. It operates on supply voltages of 110 V AC, 230 V AC, and 24 V DC, making it versatile for various industrial electrical control applications.

This relay offers dependable monitoring by accepting inputs from RS inductive proximity switches, open collector transistors, or relay contacts. An integrated 24 V DC onboard supply supports proximity devices, while a dedicated output can drive a 100 μA full-scale deflection moving coil meter to indicate machine speeds.

The device includes visual LED indicators that provide clear relay status and supply monitoring at a glance, helping to quickly diagnose operational conditions and faults. Its compact DIN standard housing is designed with an 11-pin socket, allowing easy mounting either on the front panel or within chassis environments.

The contact configuration of SPDT supports switching voltages up to 240 V AC and a contact current rating of 5 A, suitable for controlling indicators or alarms linked to machine speed anomalies. The relay terminals use screw-type connectors to ensure secure and robust wiring under industrial conditions.

Rated for an IP40 ingress protection, the relay is resistant to moderate dust intrusion but suitable for indoor electrical panels. This unit can reliably operate across an industrial temperature range, from +50°C minimum to a maximum of 50°C, fulfilling the thermal requirements of typical manufacturing and automation environments.

Compliance with CE marking standards ensures that this monitoring relay meets essential low voltage directives (EN61010-1) and electromagnetic compatibility directives (EN50081-1 / EN50082-1), guaranteeing safe and interference-resistant operation.

Designed for reliable speed monitoring of industrial machinery. Accepts multiple input types, including proximity switches and relays. On-board 24 V DC supply for proximity devices included. LED indication for relay status and power supply diagnostics.

Compact DIN rail mount with standard panel cut-out dimensions. SPDT contact configuration rated for 5 A and 240 V AC switching. IP40 protection suitable for indoor panel installations. Operates reliably within +50°C to 50°C temperature range.

Meets CE safety and EMC standards for industrial use.

This monitoring relay is ideal for industrial, manufacturing, automation, and electrical panel applications where precise rotational speed measurement and control are critical. It supports both AC and DC supply voltages and fits standard DIN rail mounting systems common in electrical control cabinets.
