Control & Timing Relays

RZ7-FS Electronic Timing Relays

Offers 19 different Output Functions

Precision timing relays for any industrial application

Sprecher + Schuh's RZ7-FS precision electronic timing relays offer 19 different output functions applicable to all types of industrial control. In addition to standard ON-Delay and OFF-Delay relays, the series also includes many specials such as an OFF-Delay that operates without supply voltage. Various timing ranges from 0.05 seconds to 60 hours are available, with many relays offering multi-time setting capability in the same device.

Solid state accuracy and reliability

Except for their hard silver contacts, all RZ7-FS timing relays are built with solid state electronics and controlled by a microprocessor. They are accurate to within 0.2 percent. Their ruggedness and high level of accuracy is due to the thorough testing of function, timing characteristics and surge voltage strength performed on each device prior to shipment.

RZ7-FSEliminates additional relays

The standard RZ7-FS is supplied with one single pole double throw (SPDT) contact within a compact case only 22.5mm wide. If more contacts are required, several relays are available that provide two separate, electrically isolated SPDT contacts within the same narrow footprint.

Multiple functions and timing ranges in one relay

RZ7 Hazardous Location Electronic Timers

The RZ7-FSM combines eight separate timing functions (plus ON and OFF functions) into one device. In addition, ten timing ranges are individually selectable from 0.05 seconds to 60 hours. These special relays reduce inventories and are ideal for maintaining remote installations where stocking several different timing relays would not be practical.

Hazardous Location Models

The RZ7-FS-..-EX relays are certified for use in hazardous locations such as oil, gas and petrochemical industries. This multifunctional relay includes 8 single-function, SPDT or DPDT contact output, and adjustable timing ranges. Available as a one-pole or two-pole unit, it includes cULus approvals for Industrial Control Equipment and Atex.

International Standards and Approvals

International Standards and Approvals

All Sprecher + Schuh RZ7-FS Electronic Timing Relays are UL-listed and CSA-approved. They also carry the CE mark. The RZ7-FS-..-EX models are Atex approved for use in hazardous locations.
