SmartStepTM Switch/Relay Driver (P/N 193-8015-000) Simplifies Device Control & Subsystem Design! Description MCE / Weinschel's SmartStepTM Switch/Relay Drivers (P/N 193-8015-000) were specifically designed for controlling a wide variety of electromechanical switches and other TTL devices. For example this standard design contains eight electromechanical relays for output and control. Applications Samples 1-3 below illustrate a few of the configurations possible with the Model 8015. The relays are Form C (SPDT) latching type which along with various jumper configurations, can be used with the 8210A to control a variety of devices such as RF Switches (+28V and latching) and other TTL compatible devices. This card also provides an optional three-pin External Power connector which can be used to supply power to the device's) under control, to simplify wiring. The Relay Driver Card provides eight electromechanical relays for output and control. The relays are Form C (SPDT) latching type which, along with various jumper configurations, can be used with the 8210A controller interface to control a variety of devices. Sample 1: TTL Device Control The Relay Card interfaces to the Weinschel Model 8210A via the Device Interface Bus (J1), a 14-pin ribbon cable which provides communications and power to the Relay Driver Card from the Model 8210A. This card also provides an optional three-pin External Power connector (J4) which can be used to supply power to the device(s) under control, to simplify wiring. This External Power is not used by the control circuitry on the Relay Driver, and its use is completely application dependent. Each relay (shown below) contains a number of user-configurable jumpers which allow the output connections to supply power and/or ground to the devices under control. There are provisions for the user to install their own components on the outputs, which may include pull-up/pull-down resistors, filter caps, EMF suppression diodes, etc. Sample 2: +28 V RF Switch Sample 3: Latching RF Switch 5305 Spectrum Drive, Frederick, MD 21703-7362 TEL: 301-846-9222, 800-638-2048 Fax: 301-846-9116 web: www.weinschel.com email: sales@weinschel.com 181 4/30/02 Specifications DRIVER INTERFACE: Input Supply Voltage: Control Signals: Interface Modes +12 to +15 Vdc Control Signals TTL/CMOS compatible Access.Bus protocols DC Characteristics: Driver Interface (D0-D7, /I2C, /RST): Minimum Maximum -0.5 V 0.8 V Signals (Description) VIL (Input Low Voltage): VIH (Input High Voltage): 2.0 V 5.25 V Ipu (Input Pullup Current): 50 A 400 A 11.0 V 16.0 V Power Supply: VIN (Supply Voltage): IIN (Supply Current, digital section): ICELL (Supply Current per relay): 15 mA Number of Relays: 8 Relay Type: SPDT (Form C), Latching Maximum Switching Voltage: AC 125 Vac DC 220 Vdc Maximum Switching Capacity: AC 0.5 A @ 125 Vac DC 2.0 A @ 30 Vdc Minimum Switching Capacity: 10 mA @ 10 mVdc Initial Contact Resistance: 75 mW Contact Material: Gold-clad Silver Alloy Expected Life: Relay Release Time: 108 operations 105 operation @ 2A, 30 Vdc 2x105 operations @ 1A, 30 Vdc 4 msec Physical Dimensions -20 to +70C STORAGE TEMPERATURE: 67 to +167 F (-55 to +75 C) CONNECTORS: Device Interface Bus (DIB), J1: 14-pin 0.025" square post header @ 0.1" centers.

Designed to interface to Weinschel's new line of SmartStep programmable attenuators, the 8210A represents a new concept in device control applications for bench test and subsystem designs. The 8210A provides a high-level interface from various industry standard communications interfaces, including IEEE-488 and RS232/RS422/RS485, to the SmartStep's serial Driver Interface Bus. SmartStep Programmable Attenuators: Weinschel offers a wide range of programmable attenuators and other components that can be easily interfaced with the Model 8015 and 8210A to create subsystems in minutes and greatly simplify computer control applications.
