DSCP81
Configurable Voltage/Current Input Signal Conditioners, DIN Mount
Description
Each isolated DSCP81 signal conditioner is designed for measuring voltages up
to ±1000VDC and currents up to ±100mA. The input type, measurement range,
and other features are software configurable. A PC with RS-232C serial port, the
DSCX-787 and DSCX-587 interface cables, and the DSCX-557 configuration
software are required to program the DSCP81.
S
The DSCP81 can interface to either a current or voltage input and provide a
current or voltage output (Figure 1). The input filter characteristics, input and
output ranges, input signal linearization, signal inversion, and optional alarm
relay output are all software configurable by the user. The input signal may be
linearized using up to 50 points of interpolation. Optionally, the user may specify
all configurable parameters and request factory configuration.
• Software Configurable Filter
Two models are available offering wide-range power supply connection: 24
to 60VDC/AC, and 85 to 230VDC/AC. The DSCX-557 configuration software
allows query, print-out and saving of configuration settings, display of input
measurement value, and display of interpolation table points.
• Mounts on Standard DIN Rail
Features
• Interfaces to Voltages up to ±1000VDC and
Currents up to ±100mA
• Software Configurable Input Type and Range
• 3700Vrms Transformer Isolation
• Supply Voltage of 24 to 60VDC/AC or 85 to
230VDC/AC
• Alarm Relay Output
• –25C to +55C Operating Temperature
• CE Compliant
There is impending danger of high voltage on any DSCP81
connections from high input voltage or high power supply voltage.

Figure 3: Configuring the DSCP81
A PC, DSCX-787 PC interface cable, DSCX-587 module interface cable, and
DSCX-557 configuration software are required to program the DSCP81.
Power must be connected to the DSCP81 for configuration. The DSCX-557
configuration software is downloadable from the website.
IMPORTANT!
1. DO NOT connect the DSCX-587 module interface cable to the DSCP81
programming connector when >253 V is applied to the DSCP81 input.
2. The DSCX-587 module interface cable must first be connected to the
DSCX-787 cable before it is connected to the DSCP81.
3. The programming connector on the DSCP81 is DC connected to the
DSCP81 input circuit. DO NOT touch any metal parts of the plug or socket
if an input voltage >24 V is connected to the DSCP81.
