Description

Description

The DP2000/9000-O is a panel mount resistance meterwith direct readout in ohms. Resistance ranges arejumper selectable. It is complete with current excitationand open resistance detection. With the addition ofanalog and control outputs, it can be incorporated asa system component in ATE and closed-loop controlapplications.

Power and Display Options
Six types of power supplies are available: 120 Vac,240 Vac, 24 Vac, 5 Vdc, isolated 9 to 32 Vdc andisolated 26 to 56 Vdc. An LED display is standard, anLCD display is optional and is recommended for viewingin bright ambient light. A NEMA (IP65) 4 splash-prooflens cover is available.

Signal input and power connections are made via arear barrier terminal strip. The motherboard rear edgeconnector provides access to hold and test, polarity,clock, and the standard analog output and optionalanalog outputs. Decimal point positions can be selectedby jumpers.

Analog Output Options
A 1 mV/count (±2 V full-scale) or 0.1 mV/count (±1 Vfull-scale) analog output is standard and is ideal fordriving a strip-chart recorder. An additional analogoutput can be provided by an optional vertical pluginboard. Available output signals are 0 to 5 Vdc, 0 to10 Vdc, 0 to 1 mA (source or sink) and 4 to 20 mA(source or sink). The top and bottom of each outputrange can be scaled to fit a user-selected display span.

Control Output Options
Additional outputs can be provided by a horizontalupper board. Available options include single-setpointcontrol with one 10 A relay, dual-setpoint controlwith two 10 A relays, 4 to 20 mA proportional control(source or sink), time-proportional 2 A solid-state relaycontrol, and isolated, parallel BCD output.
