The DP-158 is a programmable 8, 16 or 32 channel measurement and alarm centre. In addition to
measurement inputs the centre has inputs for 8 relay contact circuits.
In addition to, the actual measurement and alarm operation, the centre is equipped with memory storage,
inhibit, control, and report functions.
Measurement results are channel specific according to the users choice: temperature (Pt-100 ohm RTD /
thermocouple) or voltage/current/resistance with scaleable display for pressure, humidity, flow, surface
height and other measurements.
Relay contact inputs are voltage free, opening or closing contacts. Contact inputs are used either as
independent alarm circuits or in measurement limit value operations for inhibiting or locking actions.
Using the two serial outputs, the DP-158 centre may be connected to a PC or a printer, relay control units,
parallel light board, as well as other data handling and transfer equipment.
Reading of values and programming uses the 2 x 20 character alphanumeric display and the 8 front panel
push buttons. The center is also equipped with indicator lights to show the most important events and
The standard power supply is 230V 50Hz mains supply but on separate order the centre may be supplied
with 18 –36 VDC.
