| CT2100-400 MICROPROCESSOR CONTROLLED QUAD SOLID STATE RELAY Features * 4 Independent 1.0 Amp Switches CIRCUIT TECHNOLOGY * 600 Volts Isolation between Switches www.aeroflex.com/act1.htm * Operates from a 5 Volt Logic and 15 Volt Bias * D.C. Trip Level 1.3 Amps * Switches are Designed to withstand Electro-Magnetic Pulse (EMP) * Functions and Operates from -55C to +125C in Military Environments * Processed and Screened to Mil-STD-883 Specifications The CT2100-400 is a microprocessor controlled, quad solid state relay that incorporates fully isolated switch control and built-in test. The hybrid provides 600 Volts isolation between control inputs and switch outputs. Internal control and status registers provide analog switch function which operates via simple I/O commands.

The device has been designed to provide an interface which operates as a simple computer I/O port. The switches are controlled by a single data word which the processor writes to an internal control latch. In addition to the basic switch function ON/OFF and Trip flags provide the operational status of each of the four switches. These signals are internally contained in an 8 bit status register which is accessible by an I/O read command. The switches may also be controlled asynchronously (without write strobes) by use of separate initialization pins. These may also be used for Power-Up control in a microprocessor based system. The CT2100-400 has four independent fully isolated switches which may be used as high side or low side drivers. The isolated design allows the user to parallel devices or place them in series as required for the specific application. Control of the switch is via I/O write (Address 0) or asynchronous control lines. The CT2100-400 has an internal switch control latch which is updated via subsystem I/O write as illustrated in Figure 2. Once the I/O write is completed the switch is latched into the OFF or ON state. The switch may also be controlled via individual PRESET and CLEAR lines. These lines asynchronously drive the switch control latch without the need for a write strobe. The PRESET/CLEAR inputs are enabled by the initialize pin. SWITCH STATUS Each switch in the CT2100-400 is monitored for circuit Trip and ON/OFF. This data is contained in a 8 bit status register which is accessible via an I/O read (Address 0) command. The timing for the I/O read is shown in Figure 1. The Trip and ON/OFF flags are provided to the system to assess the operational capability of the switch versus the status of the controlled load. The Trip bit is set high when the switch has conducted between 1.1 to 3 amps of current based on the time to trip curve in Figure 3. The over current DC trip point is typically 1.3 amps.
