Applications

Control Inputs:
SLAVE terminal used as an input from remote push-button or switch turns on relay when that switch is on. Activation is by connecting this input to Ground. Input from other equipment's open-collector output turns relay on when open-collector is on.
Note: RDL switching STICK-ONs have open-collector outputs suitable for driving an ST-LCR1.
5V+ accepts 3.5 to 12 Vdc to turn on relay. Relay is on only when this control signal is applied.
24V+ accepts 12 to 35 Vdc to turn on relay. Relay is on only when this control signal is applied.
Control Output:
SLAVE terminal open-collector @ 25 mA suitable to drive indicators or slave LCRs
Switching Contacts:
Double-pole, double-throw

STICK-ON SERIES

STICK-ONs are the original application-specific modules for the A/V, recording and broadcast industries. Module functions include signal detection, switching, pre-amplification, format conversion, line driving, power amplification, mixing, distribution, gain control, equalization, routing and more. Each STICK-ON is an ultra-compact module engineered to provide higher performance and longer life than other industry products. STICK-ON modules are solid encapsulated hybrid circuits in durable industrial black plastic enclosures (1.55", 3.94 cm x 3", 7.62 cm x 0.65", 1.65 cm) with clear bold white lettering for the terminal block connections, recessed trimming controls and switches.

Since RDL first originated application-specific modules, STICK-ONs have led the industry in economical, high-performance and cost-effective long life solutions in system designs. Multiple STICK-ON modules can be interconnected to form all or part of an A/V system. A single STICK-ON module may be mounted right where its function is needed, often to add an input, output, or gain adjustment to existing equipment. STICK-ON modules allow customizing an A/V system to precisely match users’ needs. Adding STICK-ONs to an existing system can extend system life by adding updated features, resulting in considerable cost savings. A complete range of backboard and rack mounting options is available for systems comprised of multiple STICK-ON modules.

The technology used in STICK-ON modules has been regularly updated over the years to insure industry-leading performance. Functions and features provided by STICK-ONs, since their introduction, are still available today. This continuity in product offering and support makes STICK-ON modules the preferred long-term resource for system design solutions. STICK-ON SERIES modules are designed and manufactured in the U.S.A.
