Campbell Hausfeld SDM-CVO4 - Manual

SDM-CVO4 4-Channel Current/Voltage Output Module The SDM-CVO4 is a synchronously addressed datalogger peripheral. Datalogger control ports 1, 2 and 3 are used to address the SDM-CVO4 and send out data that defines the desired voltage/current output of each of the four channels. The output levels are...

Instruction Manual 2.2 Output Specifications Voltage Mode: Range: 0 – 10,000 mV Resolution: 2.5 mV Maximum Output Current: 30 mA per channel. Minimum load current: 5 μ A if output < 200 mV. A ccuracy (+23 ° C) ± 0.02% of set voltage, + ( ± 2.5 mV). A ccuracy (-25 to +50 ° C) ± 0.13% of set voltag...

SDM-CVO4 4-Channel Current/Voltage Output Module 3. Power Considerations The SDM-CVO4 power requirements are large compared to most Campbell Scientific products, especially when driving significant loads. Care must be taken to ensure that the power supply can cope with this higher demand. Alkaline b...

SDM-CVO4 4-Channel Current/Voltage Output Module 4.2 Output Device Connections For each output channel there are four terminals which are labelled V o , Id plus there are two ground ( ) connections per channel. The two ground terminals are internally connected; two are provided for convenience. 4.2....

SDM-CVO4 4-Channel Current/Voltage Output Module 4.2.3 Shield and Ground Connections It is generally advisable to used shielded (screened) cable when connecting the output to any remote system to reduce the chances of noise pickup. The shield will only be effective if it is connected to a good groun...

SDM-CVO4 4-Channel Current/Voltage Output Module this device is at the low end of its tolerance band (±10%), combined with the normal tolerance of flash test devices, then the spark gap could fire during a 1500 VAC flash test, which may cause an indication of failure. Testing at a slightly lower vol...

Instruction Manual compensated for. With the SDM-CVO4 as an excitation source, any drift in its output accuracy, or of the logger measurement accuracy, can result in a combination of those errors. It is worth investigating, therefore, the exact requirements of the sensors you wish to use. For instan...

Instruction Manual If the SDM-CVO4 loses power for any reason, when power is restored the outputs will return to the default ‘off’ state. This will be held until the datalogger runs Instruction 103 again to update the output levels required. 6.2 Edlog Program Examples The following program examples ...
