Modules for the PDW90 base station are easy to install and add functionality to the wireless system. There are four types of modules available: dual analog inputs, dual analog outputs, digital I/O, and dual relays. The analog outputs module allows the base station to output two independent analog signals being broadcast by any of the field units. The analog inputs module allows the base station to accept two analog signals and transmit them wirelessly to any of the connected field units. The digital I/O module contains four channels which can be programmed to correspond with any of the field units’ digital inputs or outputs. The dual relays module can also be controlled from any of the connected field units’ digital I/O.

Accuracy±0.03% of calibrated span ±1 count
Isolation500 V
RecalibrationAll ranges are calibrated at the factory. Recalibration is recommended at least every 12 months.
Temperature Drift0.005% of calibrated span/°C max from 0 to 65°C ambient, 0.01% of calibrated span/°C max from -40 to 0°C ambient
Input ImpedanceVoltage ranges: greater than 110 kΩ; Current ranges: < 220 Ω
Signal LossInputs will remain off (open circuit) until wireless units are reconnected.
HART TransparencyAnalog input will not interfere with existing HART communications on the wired 4-20 mA signal
Digital Output Logic High3 to 5 VDC
Digital Output Logic Low0 to 0.4 VDC
Source Current10 mA maximum output current
Sink Current1.5 mA minimum input current
Signal LossDigital output goes to logic high
Dual Relays Module
Rating2 SPDT (Form C); rated 3 A @ 30 VDC and 125/250 VAC resistive load; 1/14 HP (≈ 50 W) @ 125/250 VAC for inductive loads
Digital Input / Output Module
Digital Input Logic High3 to 5 VDC
Noise SuppressionNoise suppression is recommended for each relay contact switching inductive loads; see page 13 for details.
InitializationAfter power failure, relays will initialize to default state before reconnecting to wireless units.
Signal LossIf mapped to digital input channel, the relay energizes.
Dual 4-20 mA Output Module
Output SourceAnalog input from connected wireless unit
CalibrationFactory calibrated: 4.000 to 20.000 = 4-20 mA output
