Campbell Hausfeld SDM-CVO4 2. Specifications

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 set by four values in successive input locations in the datalogger. A total

of up to sixteen SDM-CVO4s or other SDM peripherals may be connected and

addressed from the same three ‘SDM’ ports.

For the CR10/10X, CR23X, CR7 and 21X dataloggers Instruction

103 is used to control the SDM-CVO4. This was introduced in

August 1988 for controlling SDM-AO4 functions. (The SDM-AO4

is an older voltage-output-only peripheral.) Dataloggers purchased

before this date may use a different instruction.

NOTE

The SDM-CVO4 instruction is used with the CR800, CR1000,

CR3000, and CR5000.

2. Specifications

Compatible dataloggers: CR10X, CR800, CR1000, CR3000, CR5000, and

CR7. Also compatible with many retired

dataloggers such as the CR10, 21X, and CR23X.

Operating voltage: 12 VDC nominal (8 V to 16 V)

Current drain at 12V DC: Typical active quiescent current 27 or 54 mA,

depending on operating mode (no load on output

ports). To estimate the total current, add the

quiescent current to the sum of all output currents

multiplied by 1.5.

E.g. if each port is at 10 mA output, the total = 54 +

(1.5*4*10) = 114 mA. The device can be shut down

to <0.5 mA with all outputs off.

Maximum Total SDM cable length: 6 m.

Operating temperature: -25°C to +50°C standard (-40 to 80°C optional)

Size: 176 mm wide x 111 mm high x 24 mm deep.

234 mm wide x 111 mm high x 24 mm deep when

fitted with brackets for mounting in enclosure, etc.

Mounting brackets have two holes at 203.2 mm (8")

spacing for screw fixings.

Weight: 370 g

EMC Status: Complies with EN55022-1:1998 and EN50082-

1:1998
