3. The Modbus port on the BASR master module is non isolated ElA 485 compatible When connecting to other non isolated devices care must be exercised to ensure that all non isolated Modbus devices share the same ground reference COM with the BASR master module This is usually accomplished by sharing the same power source Configure the Modbus data rate and protocol using the BASR Modbus port web page 24 VDC OUTPUT UH Figure 5 Internal Termination and Bias When connecting to a isolated 3 wire Modbus device the signal common of the isolated device must be connected to the SC pin between the MB and DN ports This ties the two reference points together for reliable communications Refer to Figure 6 for wiring details Modbus serial device can only be attached to the MB port on the master module Refer to Figure 5 for details on the bias and termination network present on the MB port Together these resistors approximate one 120 Q terminating resistor Terminal D represents the more positive connection for the EIA 485 Modbus serial network while D represents the less positive connection Make corresponding connections to Modbus serial devices The last device on the bus should have applied bias and termination or just termination A shielded twisted pair cable should be used with interconnecting devices Connect the shields together and attached to chassis at only one point Refer to Figure 6 for wiring details TD040300 0MC 18
4. 6 2 Thermistors The BAS Remote has built in calibration curves for 10 KQ Type II or Type III thermistors These devices have a non linear with a negative coefficient of resistance to temperature and provide a nominal resistance of 10 kQ at 25 C Using the web server configure an input for either Type II or Type IIl thermistor As shown in Figure 8 connect the two wire thermistor to points A and B Polarity is not an issue If averaging of temperature is desired connect multiple thermistors in a series parallel combination so that the nominal resistance remains at 10 kQ as shown Make sure that all devices are of the same type The effective range of temperature measurement is from 35 to 110 F 37 to 44 C An open input results in a fault condition that produces a red LED indication for that channel 10 KO Type Il or Type Ill Thermistors BAS Remote UP DN OUT 8 OUT 7 D D SC D D NC C NO NC C NO Figure 8 Thermistor Connections 6 3 Contact Closure The BAS Remote can sense the make or break of a contact from a relay or push button The contacts being sensed must be absent of any applied source of energy and be rated for low voltage low current switching The BAS Remote will provide the electrical energy to be sensed Using the web server configure an input for contact closure As shown in Figure 9 simply connect the contacts between points A and B For common mechanical contacts polarity is not an issue The

D040300 0MC 24 When measuring current remember the BAS Remote sinks current to ground A 250 Q impedance is effectively applied between points A and B on the input To measure current it must be driven into point A with respect to point B For two wire current transmitters the more positive point on the transmitter attaches to the 24 V on the BAS Remote loop supply or it can attached to an external loop supply as long as that loop supply has a common connection with the BAS Remote The less positive connection is made to point A on the input Care should be exercised when connecting to a three wire current transmitter These are usually non isolated devices between the power source and signal output The BAS Remote will sink current from its input to ground so the transmitter must source current from a positive potential to ground If the three wire transmitter works in this manner it can be accommodated Four wire transmitters usually have isolation between power supply and signal output so their output stage can usually be treated as a two wire transmitter 6 6 Analog Output Either voltage in the range of 0 10 VDC or current in the range of 0 20 mA can be outputted by assigning analog outputs Configure an output using a web page Select the appropriate range For DC voltage the output voltage is applied to point A with respect to common For DC current the output current is sourced from point A to common so there is no need for a loop
