FSRST Shaft Rotation Sensors Models Available FSRST Shaft Rotation Sensor The Tempatron FSRST shaft rotation sensor is designed to prevent Product Features Prevents access to rotating machinery NPN sensor or voltage free input Supply voltage 110Vac or 230Vac 1 to 30 second adjustable time delay Standard DIN48 square size Plug-in socket or panel mounting Matching timers available Matching temp. controllers available Plug-in sockets also available sensor does not receive a pulse within the adjustable time setting, the access to a rotating machine until it has slowed to a safe speed. If the output relay will energise which can then disable a machine guard to enable safe access by the machine operator. The shaft rotation sensor is housed in a compact DIN48 square enclosure which can either panel mount or surface/DIN rail mount to a socket and is auxiliary powered from either 110Vac or 230Vac. The 5 Amp rated single pole changeover relay output contact is isolated from the supply voltage, and use of the normally open contacts enables failsafe operation in the event of power failure. The FSRST has two LEDs to indicate both power and relay status. For prevention of access to rotating machinery or equipment Dimensions Switch Input Brown Blue Panel cutout 45mm square (-0.0/+0.5) Note: A switch input (relay contact, reed switch or open collector transistor etc.) may be used across terminals 5 and 7 as an alternative input to the unit instead of the NPN proximity sensor. When using a switch input, a resistor (approximate value 4.7k ohm) must be connected between terminals 6 and 7.
