All OP Amps are TL082 or TL084

Analog Ground is separated from Chassis Ground. Electrically they are separated by an RC network.

See recommended terminal tightening torques in Section 7.

Analog Outputs

Two programmable analog outputs are provided on J1-6 and J1-7. See Figure 3-14.

 

These outputs are scaled 0 - 5 VDC (1mA maximum output current) and can be used to

 

provide real-time status of various control conditions. The output conditions are defined

 

in Table 4-4of Section 4 of this manual.

 

 

 

 

The return for these outputs is J1-1 analog ground. Each output is programmed in the

 

Level 1 Output block.
