Analog/Digital Trainers

Great for students, technicians, and engineers.

Choose from Graymark's broad line of Trainers/Designers for fast, easy circuit breadboarding and testing. All connections and controls are clearly marked and conveniently located. Nickel-plated breadboard terminals provide reliable connections while internal PCB construction offers long-lasting dependability. The 110 VAC inputs are fused and power supplies have overcurrent protection.

Removable Breadboards - use 1 Trainer for several students or different circuits. Extra Breadboards are available.

Advanced Breadboard Design - 6 interconnected tie points per row provides maximum density for MSI, LSI, and all DIP ICs. Row and column markings make wiring fast and easy, while nickel-plated terminals ensure reliable connections.

TR5 and TR6

Both have a 5-range function generator. TR5 has a 30VDC Voltmeter, 100µA ammeter and a 2-pole 6-position rotary switch. TR6 has a 3-1/2 digit DVM with 4 ranges, and 2 function switches.


TR7 and TR8

Both have a universal connector holder. TR7 is supplied with a 60-pin header while TR8 comes with DB-25 (male and female) connectors. Extra 60-pin and DB-25 connectors, as well as optional card edge connectors are available.

TR7 has a 5-range function generator, while TR8 has a 6-range pulse generator. The TR8 Logic Probe and Logic LEDs have a TTL/CMOS (Tri-State) Mode Switch.

TR9

5 plug-in modules (including a 6-range clock generator and a 20-button keyboard), and an assortment of jumpers make the TR9 the best choice for a versatile, portable trainer. An attractive, durable Carry Case included.
