4.9 CURRENT TRANSMITTER INPUTS

Current inputs are accommodated by placing resistors in the input section to convert the

current input into a voltage. Different current input ranges are accommodated by

selecting the proper resistor values. In general RC is selected to maintain a low source

resistance. RA and RC produce the input full scale of 60mv. The positive input should be

connected to the AUX terminal, and the negative input to the LOW terminal.

The following input values are suggested:

4 to 20 ma 0 to 10 ma

RA = 93.3 ohms RA = 26.7 ohms

RB = 20.0 ohms RB = 20.0 ohms

RC = 20.0 ohms RC = 20.0 ohms

Please note section 4.5 regarding the shield connection.

Please note section 4.11 regarding scaling and calibration.

4.10 INFRARED NON-CONTACT TEMPERATURE SENSORS

The ANAFAZE 8 IRSM infrared sensing module is ideally suited for many infrared non-

contact temperature applications. It can be supplied by ANAFAZE as a fully integrated

system with the controller configured to provide sensor power and for direct connection

of the sensor input. The following connections are required if the IRSM internal ambient

sensor is not used:

ANAFAZE 8 PID IRSM WIRES

Pin Color Function

AUX A Orange Signal out

HIGH -- no connection --

LOW B White Signal ground

SHLD K Shield Shield

SPARE 1 (+5vdc) E Red +5vdc supply

SPARE 2 (pwr gnd) C Black power ground

SPARE 2 (pwr gnd) J Brown no peak hold

No connections D Green +15vdc supply

F Blue Ambient sensor

H Yellow Track and hold

Resistor Values -- input is 0 to 10ma for 0 to 1000 deg F

RA RA = 26.7 ohms

RB RB = 20.0 ohms

RC RC = 20.0 ohms

RD RD = not used

If desired a second input can be used to monitor the IRSM internal ambient temperature.
