Module, Input, Single Channel, ±10V Voltage, RS-232 Output (Used)

Description

Module, Input, Single Channel, ±10V Voltage, RS-232 Output
DGH #D1141
The D1000 analog input modules are complete single-channel data acquisition systems that are well suited to applications such as SCADA, data loggers, PLC’s, and process controllers.
The D1000 communicates using the DGH ASCII protocol.
The single analog input D1000  series also includes discrete digital I/O bits for controlling solid state relays or sensing contact closures.
The DGH voltage input product line converts analog DC voltage signals to digital information, linearizes the digital data and communicates the values to a host computer or PLC. The data values are transmitted to a host computer via an RS-232 serial communications link using either an ASCII protoco.
The D1100 series modules convert and linearize DC voltages to engineering units scaled in millivolts. The values are communicated to a host computer using an ASCII protocol over either RS-232 serial communications link.
