Analog Stimulus Isolator Model 2200
The Model 2200 is an optically isolated analogue stimulus isolator, designed to convert any waveform from an external source into constant current or constant voltage pulses, while ensuring complete signal isolation. It runs on two rechargeable batteries (9 V for control, 12 V for output), guaranteeing up to 8 hours of continuous autonomy. It has a TTL gate port to switch the pulse on or off, and a self-diagnostic error indicator.
Features of theAnalog Stimulus Isolator Model 2200
- Provides opto-electrical isolation for signals generated by various analogue sources
- Constant current or constant voltage output, switchable via range selector
- Compatible with single or two-phase modes, up to ±50 V and ±5 mA
- Wide bandwidth up to DC-40 kHz, with rise time < 10 µs
- Very low noise : < 0.003% full scale (~150 pA RMS in current mode)
- Powered by two internal rechargeable batteries, operating time ≈ 8 h
- TTL “Control Gate” port to remotely enable or disable the output signal
- Error LED indicator lights up if the output signal does not follow the analogue input
