Instruction Manual

RA, RB, RC, and RD are selected separately for each input and are labeled on the PC

board for each loop. CH 1 (channel 1) is loop 1 etc. Resistors should be 1% metal film,

1/4 watt or better for higher accuracy. Other components such as capacitors can also be

installed when required for signal conditioning. Please consult ANAFAZE. The resistors

are normally soldered on the component side of the main PC board before installation.

The silk screen shows the location of each input. The locations and interconnections are

shown below for a typical input:

4.7 VOLTAGE INPUTS

Voltage inputs should be connected with the positive side to the HIGH terminal and the

negative side to the LOW terminal. The input range is 0 to 60 mv. Signals greater than

60 mv must be scaled with resistors to match the input full scale to 60 mv. For scaling

the positive input should be connected to the AUX terminal and the negative input to the

LOW terminal. Typical scaling resistors are as follows:

0 to 5v 0 to 10v

RA = 4.75k RA = 4.75k

RB = 649 ohms RB = 301 ohms

Please note section 4.5 regarding the shield connection.

Please note section 4.11 regarding scaling and calibration.

Using the suggested input, scaling resistors may cause additional error due to the value

of R[b]. This possible error can be corrected by using MX+b. Call ANAFAZE for

assistance.

4.8 THERMOCOUPLE INPUTS

All thermocouple types may be directly connected to the ANAFAZE 8 PID. Types J,K,

and T linearization and cold junction compensation are provided standard in the

ANAFAZE 8 PID. For other thermocouple types, optional input ranges are required.

Thermocouples should be connected with the positive lead to the HIGH terminal and the

negative lead to the LOW terminal. Note section 4.5 on shielding.
